C-C chemokine receptor-like 2 [Mus musculus]

Protein Classification

G protein-coupled receptor family protein; olfactory receptor( domain architecture ID 11606903)

G protein-coupled receptor family protein is a seven-transmembrane G protein-coupled receptor (7TM-GPCR) family protein which typically transmits an extracellular signal into the cell by the conformational rearrangement of the 7TM helices and by the subsequent binding and activation of an intracellular heterotrimeric G protein; GPCR ligands include light-sensitive compounds, odors, pheromones, hormones, and neurotransmitters; olfactory receptor plays a central role in olfaction or the sense of smell, similar to human family 6 olfactory receptors; belongs to the class A rhodopsin-like family of G protein-coupled receptors; binding of an odorant to the olfactory receptor induces a conformational change that leads to the activation of the olfactory-specific G protein (Golf)

CC chemokine receptor-like 2, member of the class A family of seven-transmembrane G protein-coupled receptors; Chemokine (CC-motif) receptor-like 2 (CCRL2) is a member of the atypical chemokine receptor family. CCRL2, like other atypical receptors, has an alteration in the conserved DRYLAIV motif in the third intracellular loop, which is essential for GPCR coupling and signaling. CCR2L is expressed in most hematopoietic cells and many lymphoid organs as well as in heart and lung. CCRL2 was initially reported to promote chemotaxis and calcium fluxes in responses to chemokines (CCL2, CCL5, CCL7, and CCL8); however, these results are still controversial. More recently, chemerin, a chemotactic agonist of CMKLR1 (chemokine-like receptor-1) and GPR1, was identified as a novel non-signaling ligand for both human and mouse CCRL2. Chemokines are principal regulators for leukocyte trafficking, recruitment, and activation. Chemokine family membership is defined on the basis of sequence homology and on the presence of variations on a conserved cysteine motif, which allows the family to further divide into four subfamilies (CC, CXC, XC, and CX3C).

55-304 1.66e-30

7 transmembrane receptor (rhodopsin family); This family contains, amongst other G-protein-coupled receptors (GCPRs), members of the opsin family, which have been considered to be typical members of the rhodopsin superfamily. They share several motifs, mainly the seven transmembrane helices, GCPRs of the rhodopsin superfamily. All opsins bind a chromophore, such as 11-cis-retinal. The function of most opsins other than the photoisomerases is split into two steps: light absorption and G-protein activation. Photoisomerases, on the other hand, are not coupled to G-proteins - they are thought to generate and supply the chromophore that is used by visual opsins.

47-316 1.96e-62

CC chemokine receptor types 5 and 2, member of the class A family of seven-transmembrane G protein-coupled receptors; CCR2 and CCR5 share very high amino acid sequence identity. Both receptors play important roles in the trafficking of monocytes/macrophages and are implicated in the pathogenesis of immunologic diseases (rheumatoid arthritis, celiac disease, and transplant rejection) and cardiovascular diseases (atherosclerosis and autoimmune hepatitis). CCR2 is a receptor specific for members of the monocyte chemotactic protein family, including CCL2, CCL7, and CCL13. Conversely, CCR5 is a major co-receptor for HIV infection and binds many CC chemokine ligands, including CC chemokine ligands including CCL2, CCL3, CCL4, CCL5, CCL11, CCL13, CCL14, and CCL16. CCR2 is expressed primarily on blood monocytes and memory T cells, whereas CCR5 is expressed on antigen-presenting cells (macrophages and dendritic cells) and activated T effector cells. Chemokines are principal regulators for leukocyte trafficking, recruitment, and activation. Chemokine family membership is defined on the basis of sequence homology and on the presence of variations on a conserved cysteine motif, which allows the family to further divide into four subfamilies (CC, CXC, XC, and CX3C). Chemokines interact with seven-transmembrane receptors which are typically coupled to G protein for signaling. Currently, there are ten known receptors for CC chemokines, seven for CXC chemokines, and single receptors for the XC and CX3C chemokines.

classical and atypical chemokine receptors, member of the class A family of seven-transmembrane G protein-coupled receptors; Chemokines are principal regulators for leukocyte trafficking, recruitment, and activation. Chemokine family membership is defined on the basis of sequence homology and on the presence of variations on a conserved cysteine motif, which allows the family to further divide into four subfamilies (CC, CXC, XC, and CX3C). Chemokines interact with seven-transmembrane receptors which are typically coupled to G protein for signaling. Currently, there are ten known receptors for CC chemokines, seven for CXC chemokines, and single receptors for the XC and CX3C chemokines. In addition to these classical chemokine receptors, there exists a subfamily of atypical chemokine receptors (ACKRs) that are unable to couple to G-proteins and, instead, they preferentially mediate beta-arrestin dependent processes, such as receptor internalization, after ligand binding. The classical chemokine receptors contain a conserved DRYLAIV motif in the second intracellular loop, which is required for G-protein coupling. However, the ACKRs lack this conserved motif and fail to couple to G-proteins and induce classical GPCR signaling. Five receptors have been identified for the ACKR family, including CC-chemokine receptors like 1 and 2 (CCRL1 and CCRL2), CXCR7, Duffy antigen receptor for chemokine (DARC), and D6. Both ACKR1 (DARC) and ACKR3 (CXCR7) show low sequence homology to the classic chemokine receptors.

CC chemokine receptor type 1, member of the class A family of seven-transmembrane G protein-coupled receptors; CCR1 is widely expressed on both hematopoietic and non-hematopoietic cells and binds to the inflammatory CC chemokines CCL3, CCL5, CCL6, CCL9, CCL15, and CCL23. CCR1 activates the typical chemokine signaling pathway through the G(i/o) type of G proteins, causing inhibition of adenylate cyclase and stimulation of phospholipase C, PKC, calcium flux, and PLA2. Chemokines are principal regulators for leukocyte trafficking, recruitment, and activation. Chemokine family membership is defined on the basis of sequence homology and on the presence of variations on a conserved cysteine motif, which allows the family to further divide into four subfamilies (CC, CXC, XC, and CX3C).

47-316 9.15e-53

CC chemokine receptor type 3, member of the class A family of seven-transmembrane G protein-coupled receptors; CCR3 is a highly promiscuous receptor that binds a variety of inflammatory CC-type chemokines, including CCL11 (eotaxin-1), CCL3L1, CCL5 (regulated on activation, normal T cell expressed and secreted; RANTES), CCL7 (monocyte-specific chemokine 3 or MCP-3), CCL8 (MCP-2), CCL11, CCL13 (MCP-4), CCL15, CCL24 (eotaxin-2), CCL26 (eotaxin-3), and CCL28. Among these, the eosinophil chemotactic chemokines (CCL11, CCL24, and CCL26) are the most potent and specific ligands. In addition to eosinophil, CCR3 is expressed on cells involved in allergic responses, such as basophils, Th2 lymphocytes, and mast cells. Chemokines are principal regulators for leukocyte trafficking, recruitment, and activation. Chemokine family membership is defined on the basis of sequence homology and on the presence of variations on a conserved cysteine motif, which allows the family to further divide into four subfamilies (CC, CXC, XC, and CX3C). Chemokines interact with seven-transmembrane receptors which are typically coupled to G protein for signaling.

CC chemokine receptor type 8, member of the class A family of seven-transmembrane G protein-coupled receptors; CCR8, the receptor for the CC chemokines CCL1 and CC16, is highly expressed on allergen-specific T-helper type 2 cells, and is implicated in the pathogenesis of human asthma. CCL1- and CCR8-expressing CD4+ effector T lymphocytes are shown to have a critical role in lung mucosal inflammatory responses. CCR8 is also a functional receptor for CCL16, a liver-expressed CC chemokine that involved in attracting lymphocytes, dendritic cells, and monocytes. Chemokines are principal regulators for leukocyte trafficking, recruitment, and activation. Chemokine family membership is defined on the basis of sequence homology and on the presence of variations on a conserved cysteine motif, which allows the family to further divide into four subfamilies (CC, CXC, XC, and CX3C).

47-307 5.13e-35

atypical chemokine receptor 4, member of the class A family of seven-transmembrane G protein-coupled receptors; ACKR4 was first reported to bind several CC chemokines including CCL19, CCL21, and CCL25 and was originally designated CCR11. AKCR4 is unable to couple to G-protein and, instead, it preferentially mediates beta-arrestin dependent processes, such as receptor internalization, after ligand binding. Thus, ACKR4 may act as a scavenger receptor to suppress the effects of proinflammatory chemokines. Unlike the classical chemokine receptors that contain a conserved DRYLAIV motif in the second intracellular loop, which is required for G-protein coupling, the ACKRs lack this conserved motif and fail to couple to G-proteins and induce classical GPCR signaling. Five receptors have been identified for the ACKR family, including CC-chemokine receptors like 1 and 2 (CCRL1 and CCRL2), CXCR7, Duffy antigen receptor for chemokine (DARC), and D6. Both ACKR1 (DARC) and ACKR3 (CXCR7) show low sequence homology to the classic chemokine receptors.

43-316 8.69e-34

XC chemokine receptor 1, member of the class A family of seven-transmembrane G protein-coupled receptors; XCR1 is a chemokine receptor specific for XCL1 and XCL2 (previously called lymphotactin alpha/beta), which differ in only two amino acids. XCL1/2 is the only member of the C chemokine subfamily, which is unique as containing only two of the four cysteines that are found in other chemokine families. Human XCL1/2 has been shown to be secreted by activated CD8+ T cells and upon activation of the innate immune system. Chemokines are principal regulators for leukocyte trafficking, recruitment, and activation. Chemokine family membership is defined on the basis of sequence homology and on the presence of variations on a conserved cysteine motif, which allows the family to further divide into four subfamilies (CC, CXC, XC, and CX3C). Chemokines interact with seven-transmembrane receptors which are typically coupled to G protein for signaling.

atypical chemokine receptor 2, member of the class A family of seven-transmembrane G protein-coupled receptors; ACKR2 (also known as D6) binds non-selectively to all inflammatory CC-chemokines, but not to homeostatic CC-chemokines involved in controlling the migration of cells. Unlike the classical chemokine receptors that contain a conserved DRYLAIV motif in the second intracellular loop, which is required for G-protein coupling, the ACKRs lack this conserved motif and fail to couple to G-proteins and induce classical GPCR signaling. Five receptors have been identified for the ACKR family, including CC-chemokine receptors like 1 and 2 (CCRL1 and CCRL2), CXCR7, Duffy antigen receptor for chemokine (DARC), and D6. Both ACKR1 (DARC) and ACKR3 (CXCR7) show low sequence homology to the classic chemokine receptors.

46-316 5.33e-33

angiotesin receptor family and its related G protein-coupled receptors, member of the class A family of seven-transmembrane G protein-coupled receptors; This group includes the angiotensin receptors, the bradykinin receptors, apelin receptor as well as putative G-protein coupled receptors (GPR15 and GPR25). Angiotensin II (Ang II), the main effector in the renin-angiotensin system, plays a crucial role in the regulation of cardiovascular homeostasis through its type 1 (AT1) and type 2 (AT2) receptors. Ang II contributes to cardiovascular diseases such as hypertension and atherosclerosis via AT1R activation. Ang II increases blood pressure through Gq-mediated activation of phospholipase C, resulting in phosphoinositide (PI) hydrolysis and increased intracellular calcium levels. Through the AT2 receptor, Ang II counteracts the vasoconstrictor action of AT1R and thereby induces vasodilation, sodium excretion, and reduction of blood pressure. Bradykinins (BK) are pro-inflammatory peptides that mediate various vascular and pain responses to tissue injury through its B1 and B2 receptors. Apelin (APJ) receptor binds the endogenous peptide ligands, apelin and Toddler/Elabela. APJ is an adipocyte-derived hormone that is ubiquitously expressed throughout the human body, and Toddler/Elabela is a short secretory peptide that is required for normal cardiac development in zebrafish. Activation of APJ receptor plays key roles in diverse physiological processes including vasoconstriction and vasodilation, cardiac muscle contractility, angiogenesis, and regulation of water balance and food intake. Orphan receptors, GPR15 and GPR25, share strong sequence homology to the angiotensin II type AT1 and AT2 receptors.

47-304 1.35e-31

CC chemokine receptor type 9, member of the class A family of seven-transmembrane G protein-coupled receptors; CCR9 is a homeostatic receptor specific for CCL25 (formerly known as thymus expressed chemokine) and is highly expressed on both immature and mature thymocytes as well as on intestinal homing T Lymphocytes and mucosal Lymphocytes. In cutaneous melanoma, activation of CCR9-CCL25 has been shown to stimulate metastasis to the small intestine. Chemokines are principal regulators for leukocyte trafficking, recruitment, and activation. Chemokine family membership is defined on the basis of sequence homology and on the presence of variations on a conserved cysteine motif, which allows the family to further divide into four subfamilies (CC, CXC, XC, and CX3C). Chemokines interact with seven-transmembrane receptors which are typically coupled to G protein for signaling. Currently, there are ten known receptors for CC chemokines, seven for CXC chemokines, and single receptors for the XC and CX3C chemokines. The CC chemokine receptors are all activating the G protein Gi.

CX3C chemokine receptor 1, member of the class A family of seven-transmembrane G protein-coupled receptors; CX3CR1 is an inflammatory receptor specific for CX3CL1 (also known as fractalkine in human), which is involved in the adhesion and migration of leukocytes. The CX3C chemokine subfamily is only represented by CX3CL1, which exists in both soluble and membrane-anchored forms. Membrane-anchored form promotes strong adhesion of receptor-bearing leukocytes to CX3CL1-expressing endothelial cells. On the other hand, soluble CX3CL1, which is released by the proteolytic cleavage of membrane-anchored CX3CL1, is a potent chemoattractant for CX3CR1-expressing T cells and monocytes. Chemokine family membership is defined on the basis of sequence homology and on the presence of variations on a conserved cysteine motif, which allows the family to further divide into four subfamilies (CC, CXC, XC, and CX3C). Chemokines interact with seven-transmembrane receptors which are typically coupled to G protein for signaling.

7 transmembrane receptor (rhodopsin family); This family contains, amongst other G-protein-coupled receptors (GCPRs), members of the opsin family, which have been considered to be typical members of the rhodopsin superfamily. They share several motifs, mainly the seven transmembrane helices, GCPRs of the rhodopsin superfamily. All opsins bind a chromophore, such as 11-cis-retinal. The function of most opsins other than the photoisomerases is split into two steps: light absorption and G-protein activation. Photoisomerases, on the other hand, are not coupled to G-proteins - they are thought to generate and supply the chromophore that is used by visual opsins.

46-310 7.78e-30

CXC chemokine receptor type 3, member of the class A family of seven-transmembrane G protein-coupled receptors; CXCR3 is an inflammatory chemotactic receptor for a group of CXC chemokines distinguished by the presence of the amino acid motif ELR immediately adjacent to their CXC motif. CXCR3 specifically binds three chemokines CXCL9 (monokine induced by gamma-interferon), CXCL10 (interferon induced protein of 10 kDa), and CXCL11 (interferon inducible T-cell alpha-chemoattractant, I-TAC). CXC3R is expressed on CD4+ Th1 and CD8+ cytotoxic T lymphocytes as well as highly on innate lymphocytes, such as NK cells and NK T cells, where it may mediate the recruitment of these cells to the sites of infection and inflammation. Chemokines are principal regulators for leukocyte trafficking, recruitment, and activation. Chemokine family membership is defined on the basis of sequence homology and on the presence of variations on a conserved cysteine motif, which allows the family to further divide into four subfamilies (CC, CXC, XC, and CX3C). Chemokines interact with seven-transmembrane receptors which are typically coupled to G protein for signaling. Currently, there are ten known receptors for CC chemokines, seven for CXC chemokines, and single receptors for the XC and CX3C chemokines.

CXC chemokine receptor type 6, member of the class A family of seven-transmembrane G protein-coupled receptors; CXCR6 binds specifically to the chemokine CXCL16, which is expressed on dendritic cells, monocyte/macrophages, activated T cells, fibroblastic reticular cells, and cancer cells. CXCR6 is phylogenetically more closely related to CC-type chemokine receptors (CCR6 and CCR9) than other CXC receptors. Chemokines are principal regulators for leukocyte trafficking, recruitment, and activation. Chemokine family membership is defined on the basis of sequence homology and on the presence of variations on a conserved cysteine motif, which allows the family to further divide into four subfamilies (CC, CXC, XC, and CX3C). Chemokines interact with seven-transmembrane receptors which are typically coupled to G protein for signaling. Currently, there are ten known receptors for CC chemokines, seven for CXC chemokines, and single receptors for the XC and CX3C chemokines.

CC chemokine receptor type 10, member of the class A family of seven-transmembrane G protein-coupled receptors; CCR10 is a homeostatic receptor specific for two C-C motif chemokines, CCL27 and CCL28. Activation of CCR10 by its two ligands mediates diverse activities, ranging from leukocyte trafficking to skin cancer. Chemokines are principal regulators for leukocyte trafficking, recruitment, and activation. Chemokine family membership is defined on the basis of sequence homology and on the presence of variations on a conserved cysteine motif, which allows the family to further divide into four subfamilies (CC, CXC, XC, and CX3C). Chemokines interact with seven-transmembrane receptors which are typically coupled to G protein for signaling. Currently, there are ten known receptors for CC chemokines, seven for CXC chemokines, and single receptors for the XC and CX3C chemokines. The CC chemokine receptors are all activating the G protein Gi.

43-307 2.27e-26

rhodopsin receptor-like class A family of the seven-transmembrane G protein-coupled receptor superfamily; Class A rhodopsin-like receptors constitute about 90% of all GPCRs. The class A GPCRs include the light-sensitive rhodopsin as well as receptors for biogenic amines, lipids, nucleotides, odorants, peptide hormones, and a variety of other ligands. All GPCRs have a common structural architecture comprising of seven-transmembrane (TM) alpha-helices interconnected by three extracellular and three intracellular loops. A general feature of GPCR signaling is agonist-induced conformational changes in the receptors, leading to activation of the heterotrimeric G proteins, which consist of the guanine nucleotide-binding G-alpha subunit and the dimeric G-beta-gamma subunits. The activated G proteins then bind to and activate numerous downstream effector proteins, which generate second messengers that mediate a broad range of cellular and physiological processes. Based on sequence similarity, GPCRs can be divided into six major classes: class A (rhodopsin-like family), class B (Methuselah-like, adhesion and secretin-like receptor family), class C (metabotropic glutamate receptor family), class D (fungal mating pheromone receptors), class E (cAMP receptor family), and class F (frizzled/smoothened receptor family). Nearly 800 human GPCR genes have been identified and are involved essentially in all major physiological processes. Approximately 40% of clinically marketed drugs mediate their effects through modulation of GPCR function for the treatment of a variety of human diseases including bacterial infections.

43-304 2.74e-26

CXC chemokine receptor types 1 and 2, member of the class A family of seven-transmembrane G protein-coupled receptors; CXCR1 and CXCR2 are closely related chemotactic receptors for a group of CXC chemokines distinguished by the presence of the amino acid motif ELR immediately adjacent to their CXC motif. Expression of CXCR1 and CXCR2 is strictly controlled in neutrophils by external stimuli such as lipopolysaccharide (LPS), tumor necrosis factor (TNF)-alpha, Toll-like receptor agonists, and nitric oxide. CXCL8 (formerly known as interleukin-8) binds with high-affinity and activates both receptors. CXCR1 also binds CXCL7 (neutrophil-activating protein-2), whereas CXCR2 non-selectively binds to all seven ELR-positive chemokines (CXCL1-7). Chemokines are principal regulators for leukocyte trafficking, recruitment, and activation. Chemokine family membership is defined on the basis of sequence homology and on the presence of variations on a conserved cysteine motif, which allows the family to further divide into four subfamilies (CC, CXC, XC, and CX3C). Chemokines interact with seven-transmembrane receptors which are typically coupled to G protein for signaling. Currently, there are ten known receptors for CC chemokines, seven for CXC chemokines, and single receptors for the XC and CX3C chemokines.

43-312 1.01e-25

opioid receptors and related proteins, member of the class A family of seven-transmembrane G protein-coupled receptors; This group includes opioid receptors, somatostatin receptors, melanin-concentrating hormone receptors (MCHRs), and neuropeptides B/W receptors. Together they constitute the opioid receptor-like family, members of the class A G-protein coupled receptors. Opioid receptors are coupled to inhibitory G proteins of the G(i/o) family and are involved in regulating a variety of physiological functions such as pain, addiction, mood, stress, epileptic seizure, and obesity, among many others. G protein-coupled somatostatin receptors (SSTRs), which display strong sequence similarity with opioid receptors, binds somatostatin (somatotropin release inhibiting factor), a polypeptide hormone that regulates a wide variety of physiological functions such as neurotransmission, cell proliferation, contractility of smooth muscle cells, and endocrine signaling as well as inhibition of the release of many secondary hormones. MCHR binds melanin concentrating hormone and is presumably involved in the neuronal regulation of food intake. Despite strong homology with somatostatin receptors, MCHR does not appear to bind somatostatin. Neuropeptides B/W receptors are primarily expressed in the CNS and stimulate the cortisol secretion by activating the adenylate cyclase- and the phospholipase C-dependent signaling pathways.

47-304 1.32e-25

CC chemokine receptor type 6, member of the class A family of seven-transmembrane G protein-coupled receptors; CCR6 is the only known receptor identified for the chemokine CCL20 (also known as macrophage inflammatory protein-3alpha, MIP-3alpha). CCR6 is expressed by all mature human B cells, effector memory T-cells, and dendritic cells found in the gut mucosal immune system. CCL20 contributes to recruitment of CCR6-expressing cells to Peyer's patches and isolated lymphoid follicles in the intestine, thereby promoting the assembly and maintenance of organized lymphoid structures. Also, CCL20 expression is highly inducible in response to inflammatory signals. Thus, CCL20 is involved in both inflammatory and homeostatic functions in the immune system. Chemokines are principal regulators for leukocyte trafficking, recruitment, and activation. Chemokine family membership is defined on the basis of sequence homology and on the presence of variations on a conserved cysteine motif, which allows the family to further divide into four subfamilies (CC, CXC, XC, and CX3C). Chemokines interact with seven-transmembrane receptors which are typically coupled to G protein for signaling. Currently, there are ten known receptors for CC chemokines, seven for CXC chemokines, and single receptors for the XC and CX3C chemokines. The CC chemokine receptors are all activating the G protein Gi.

CC chemokine receptor type 7, member of the class A family of seven-transmembrane G protein-coupled receptors; CCR7 is a major homeostatic receptor responsible for lymph node development and effective adaptive immune responses and plays a critical role in trafficking of dendritic cells and B and T lymphocytes. Its only two ligands, CCL and CCl21, are primarily produced by stromal cells in the T cell zones of lymph nodes and spleen. Chemokines are principal regulators for leukocyte trafficking, recruitment, and activation. Chemokine family membership is defined on the basis of sequence homology and on the presence of variations on a conserved cysteine motif, which allows the family to further divide into four subfamilies (CC, CXC, XC, and CX3C). Chemokines interact with seven-transmembrane receptors which are typically coupled to G protein for signaling. Currently, there are ten known receptors for CC chemokines, seven for CXC chemokines, and single receptors for the XC and CX3C chemokines. The CC chemokine receptors are all activating the G protein Gi.

47-316 4.35e-25

type 1 angiotensin II receptor, member of the class A family of seven-transmembrane G protein-coupled receptors; Angiotensin II (Ang II), the main effector in the renin-angiotensin system, plays a crucial role in the regulation of cardiovascular homeostasis through its type 1 (AT1) and type 2 (AT2) receptors. Ang II contributes to cardiovascular diseases such as hypertension and atherosclerosis via AT1R activation. Ang II increases blood pressure through Gq-mediated activation of phospholipase C, resulting in phosphoinositide (PI) hydrolysis and increased intracellular calcium levels. Through the AT2R, Ang II counteracts the vasoconstrictor action of AT1R and thereby induces vasodilation, sodium excretion, and reduction of blood pressure. Moreover, AT1R promotes cell proliferation, whereas AT2R inhibits proliferation and stimulates cell differentiation. The AT2R is highly expressed during fetal development, however it is scarcely present in adult tissues and is induced in pathological conditions. Generally, the AT1R mediates many actions of Ang II, while the AT2R is involved in the regulation of blood pressure and renal function.

CXC chemokine receptor type 5, member of the class A family of seven-transmembrane G protein-coupled receptors; CXCR5 is a B-cell selective receptor that binds specifically to the homeostatic chemokine CXCL13 and regulates adaptive immunity. The receptor is found on all peripheral blood and tonsillar B cells and is involved in lymphocyte migration (homing) to specific tissues and development of normal lymphoid tissue. Chemokines are principal regulators for leukocyte trafficking, recruitment, and activation. Chemokine family membership is defined on the basis of sequence homology and on the presence of variations on a conserved cysteine motif, which allows the family to further divide into four subfamilies (CC, CXC, XC, and CX3C). Chemokines interact with seven-transmembrane receptors which are typically coupled to G protein for signaling.

43-316 1.16e-21

anaphylatoxin receptors and related G protein-coupled chemokine receptors, member of the class A family of seven-transmembrane G protein-coupled receptors; This subfamily of G-protein coupled receptors includes anaphylatoxin receptors, formyl peptide receptors (FPR), prostaglandin D2 receptor 2, GPR1, and related chemokine receptors. The anaphylatoxin receptors are a group of G-protein coupled receptors that bind anaphylatoxins. The members of this group include C3a and C5a receptors. The formyl peptide receptors (FPRs) are chemoattractant GPCRs that involved in mediating immune responses to infection. They are expressed mainly on polymorphonuclear and mononuclear phagocytes and bind N-formyl-methionyl peptides (FMLP), which are derived from the mitochondrial proteins of ruptured host cells or invading pathogens. Chemokine receptor-like 1 (also known as chemerin receptor 23) is a GPCR for the chemoattractant adipokine chemerin, also known as retinoic acid receptor responder protein 2 (RARRES2), and for the omega-3 fatty acid derived molecule resolvin E1. Interaction with chemerin induces activation of the MAPK and PI3K signaling pathways leading to downstream functional effects, such as a decrease in immune responses, stimulation of adipogenesis, and angiogenesis. On the other hand, resolvin E1 negatively regulates the cytokine production in macrophages by reducing the activation of MAPK1/3 and NF-kB pathways. Prostaglandin D2 receptor, also known as CRTH2, is a chemoattractant G-protein coupled receptor expressed on T helper type 2 cells that binds prostaglandin D2 (PGD2). PGD2 functions as a mast cell-derived mediator to trigger asthmatic responses and also causes vasodilation. PGD2 exerts its inflammatory effects by binding to two G-protein coupled receptors, the D-type prostanoid receptor (DP) and PD2R2 (CRTH2). PD2R2 couples to the G protein G(i/o) type which leads to a reduction in intracellular cAMP levels and an increase in intracellular calcium. GPR1 is an orphan receptor that can be activated by the leukocyte chemoattractant chemerin, thereby suggesting that some of the anti-inflammatory actions of chemerin may be mediated through GPR1.

purinoceptor and its related proteins, member of the class A family of seven-transmembrane G protein-coupled receptors; Members of this subfamily include lysophosphatidic acid receptor, P2 purinoceptor, protease-activated receptor, platelet-activating factor receptor, Epstein-Barr virus induced gene 2, proton-sensing G protein-coupled receptors, GPR35, and GPR55, among others. All GPCRs have a common structural architecture comprising of seven-transmembrane (TM) alpha-helices interconnected by three extracellular and three intracellular loops. A general feature of GPCR signaling is agonist-induced conformational changes in the receptors, leading to activation of the heterotrimeric G proteins, which consist of the guanine nucleotide-binding G-alpha subunit and the dimeric G-beta-gamma subunits. The activated G proteins then bind to and activate numerous downstream effector proteins, which generate second messengers that mediate a broad range of cellular and physiological processes.

G protein-coupled receptor 25, member of the class A family of seven-transmembrane G protein-coupled receptors; GPR25 is an orphan G-protein coupled receptor that shares strong sequence homology to GPR15 and the angiotensin II receptors. These closely related receptors form a group within the class A G-protein coupled receptors (GPCRs). GPR15 controls homing of T cells, especially FOXP3(+) regulatory T cells, to the large intestine mucosa and thereby mediates local immune homeostasis. Moreover, GRP15-deficient mice were shown to be prone to develop more severe large intestine inflammation. Angiotensin II (Ang II), the main effector in the renin-angiotensin system, plays a crucial role in the regulation of cardiovascular homeostasis through its type 1 (AT1) and type 2 (AT2) receptors.

47-310 6.09e-20

CXC chemokine receptor type 4, member of the class A family of seven-transmembrane G protein-coupled receptors; CXCR4 is the only known G protein-coupled chemokine receptor for the key homeostatic ligand CXCL12, which is constitutively secreted by bone marrow stromal cells. Atypical chemokine receptor CXCR7 (ACKR3) also binds CXCL12, but activates signaling in a G protein-independent manner. CXCR4 is also a co-receptor for HIV infection and plays critical roles in the development of immune system during both lymphopoiesis and myelopoiesis. Chemokines are principal regulators for leukocyte trafficking, recruitment, and activation. Chemokine family membership is defined on the basis of sequence homology and on the presence of variations on a conserved cysteine motif, which allows the family to further divide into four subfamilies (CC, CXC, XC, and CX3C). Chemokines interact with seven-transmembrane receptors which are typically coupled to G protein for signaling. Currently, there are ten known receptors for CC chemokines, seven for CXC chemokines, and single receptors for the XC and CX3C chemokines.

bradykinin receptors, member of the class A family of seven-transmembrane G protein-coupled receptors; The bradykinin receptor family is a group of the seven transmembrane G-protein coupled receptors, whose endogenous ligand is the pro-inflammatory nonapeptide bradykinin that mediates various vascular and pain responses. Two major bradykinin receptor subtypes, B1 and B2, have been identified based on their pharmacological properties. The B1 receptor is rapidly induced by tissue injury and inflammation, whereas the B2 receptor is ubiquitously expressed on many tissue types. Both receptors contain three consensus sites for N-linked glycosylation in extracellular domains and couple to G(q) protein to activate phospholipase C, leading to phosphoinositide hydrolysis and intracellular calcium mobilization. They can also interact with G(i) protein to inhibit adenylate cyclase and activate the MAPK (mitogen-activated protein kinase) pathways.

opioid receptor subtype mu, member of the class A family of seven-transmembrane G protein-coupled receptors; The mu-opioid receptor binds endogenous opioids such as beta-endorphin and endomorphin. The opioid receptor family is composed of four major subtypes: mu (MOP), delta (DOP), kappa (KOP) opioid receptors, and the nociceptin/orphanin FQ peptide receptor (NOP). They are distributed widely in the central nervous system and respond to classic alkaloid opiates, such as morphine and heroin, as well as to endogenous peptide ligands, which include dynorphins, enkephalins, endorphins, endomorphins, and nociceptin. Opioid receptors are coupled to inhibitory G proteins of the G(i/o) family and involved in regulating a variety of physiological functions such as pain, addiction, mood, stress, epileptic seizure, and obesity, among many others.

37-309 6.52e-19

bradykinin receptor B1, member of the class A family of seven-transmembrane G protein-coupled receptors; The bradykinin receptor family is a group of the seven transmembrane G-protein coupled receptors, whose endogenous ligand is the pro-inflammatory nonapeptide bradykinin that mediates various vascular and pain responses. Two major bradykinin receptor subtypes, B1 and B2, have been identified based on their pharmacological properties. The B1 receptor is rapidly induced by tissue injury and inflammation, whereas the B2 receptor is ubiquitously expressed on many tissue types. Both receptors contain three consensus sites for N-linked glycosylation in extracellular domains and couple to G(q) protein to activate phospholipase C, leading to phosphoinositide hydrolysis and intracellular calcium mobilization. They can also interact with G(i) protein to inhibit adenylate cyclase and activate the MAPK (mitogen-activated protein kinase) pathways.

43-309 6.73e-18

CXC chemokine receptor 7, member of the class A family of seven-transmembrane G protein-coupled receptors; ACKR3, also known as CXCR7, is an atypical chemokine receptor for CXCL12 and CXCR11. Unlike the classical chemokine receptors, ACKR3 contains a DRYLSIT-sequence instead of the conserved DRYLAIV motif in the second intracellular loop, which is required for G-protein coupling. Thus, ACKR3 does not activate classical GPCR signaling, instead induces beta-arrestin recruitment which is leading to ligand internalization and MAP-kinase activation. It is acting as a scavenger for CXCL12 and, to a lesser degree, for CXCL11. ACKR3 is highly expressed by blood vascular endothelial cells in brain, in numerous embryonic and neonatal tissues, in inflamed tissues and in a variety of cancers such as lymphomas, sarcomas, prostate and breast cancers, and gliomas. Five receptors have been identified for the ACKR family, including CC-Chemokine Receptors like 1 and 2 (CCRL1 and CCRL2), CXCR7, DARC, and D6. Both ACKR1 (DARC) and ACKR3 (CXCR7) show low sequence homology to the classic chemokine receptors.

relaxin-3 like peptide receptors, member of the class A family of seven-transmembrane G protein-coupled receptors; This G protein-coupled receptor subfamily is composed of the relaxin-3 like peptide receptors, RNL3R1 and RNL3R2, and similar proteins. The relaxin-3 like peptide family includes relaxin-1, -2, -3, as well as insulin-like (INSL) peptides 3 to 6. RNL3/relaxin-3 and INSL5 are the endogenous ligands for RNL3R1 and RNL3R2, respectively. RNL3R1, also called GPCR135 or RXFP3, is predominantly expressed in the brain and is implicated in stress, anxiety, feeding, and metabolism. Insulin-like peptide 5 (INSL5), the endogenous ligand for RNL3R2 (also called GPCR142 or RXFP4), plays a role in fat and glucose metabolism. INSL5 is highly expressed in human rectal and colon tissues. Both RNL3R1 and RNL3R2 signal through G(i) protein and inhibit adenylate cyclase, thereby inhibit cAMP accumulation. RNL3R1 is shown to activate Erk1/2 signaling pathway.

opioid receptor subtype kappa, member of the class A family of seven-transmembrane G protein-coupled receptors; The kappa-opioid receptor binds the opioid peptide dynorphin as the primary endogenous ligand. The opioid receptor family is composed of four major subtypes: mu (MOP), delta (DOP), kappa (KOP) opioid receptors, and the nociceptin/orphanin FQ peptide receptor (NOP). They are distributed widely in the central nervous system and respond to classic alkaloid opiates, such as morphine and heroin, as well as to endogenous peptide ligands, which include dynorphins, enkephalins, endorphins, endomorphins, and nociceptin. Opioid receptors are coupled to inhibitory G proteins of the G(i/o) family and involved in regulating a variety of physiological functions such as pain, addiction, mood, stress, epileptic seizure, and obesity, among many others.

45-312 4.80e-17

neuropeptide Y receptors and related proteins, member of the class A family of seven-transmembrane G protein-coupled receptors; NPY is a 36-amino acid peptide neurotransmitter with a C-terminal tyrosine amide residue that is widely distributed in the brain and the autonomic nervous system of many mammalian species. NPY exerts its functions through five, G-protein coupled receptor subtypes including NPY1R, NPY2R, NPY4R, NPY5R, and NPY6R; however, NPY6R is not functional in humans. NYP receptors are also activated by its two other family members, peptide YY (PYY) and pancreatic polypeptide (PP). They typically couple to Gi or Go proteins, which leads to a decrease in adenylate cyclase activity, thereby decreasing intracellular cAMP levels, and are involved in diverse physiological roles including appetite regulation, circadian rhythm, and anxiety. Also included in this subgroup is prolactin-releasing peptide (PrRP) receptor (previously known as GPR10), which is activated by its endogenous ligand PrRP, a neuropeptide possessing C-terminal Arg-Phe-amide motif. There are two active isoforms of PrRP in mammals: one consists of 20 amino acid residues (PrRP-20) and the other consists of 31 amino acid residues (PrRP-31). PrRP receptor shows significant sequence homology to the NPY receptors, and a micromolar level of NPY can bind and completely inhibit the PrRP-evoked intracellular calcium response in PrRP receptor-expressing cells, suggesting that the PrRP receptor shares a common ancestor with the NPY receptors.

45-304 6.25e-16

type 2 angiotensin II receptor, member of the class A family of seven-transmembrane G protein-coupled receptors; Angiotensin II (Ang II), the main effector in the renin-angiotensin system, plays a crucial role in the regulation of cardiovascular homeostasis through its type 1 (AT1) and type 2 (AT2) receptors. Ang II contributes to cardiovascular diseases such as hypertension and atherosclerosis via AT1R activation. Ang II increases blood pressure through Gq-mediated activation of phospholipase C, resulting in phosphoinositide (PI) hydrolysis and increased intracellular calcium levels. Through the AT2R, Ang II counteracts the vasoconstrictor action of AT1R and thereby induces vasodilation, sodium excretion, and reduction of blood pressure. Moreover, AT1R promotes cell proliferation, whereas AT2R inhibits proliferation and stimulates cell differentiation. The AT2R is highly expressed during fetal development, however it is scarcely present in adult tissues and is induced in pathological conditions. Generally, the AT1R mediates many actions of Ang II, while the AT2R is involved in the regulation of blood pressure and renal function.

46-308 8.16e-16

nociceptin/orphanin FQ peptide receptor, member of the class A family of seven-transmembrane G protein-coupled receptors; The nociceptin (NOP) receptor binds nociceptin or orphanin FQ, a 17 amino acid endogenous neuropeptide. The NOP receptor is involved in the modulation of various brain activities including instinctive and emotional behaviors. The opioid receptor family is composed of four major subtypes: mu (MOP), delta (DOP), kappa (KOP) opioid receptors, and the nociceptin/orphanin FQ peptide receptor (NOP). They are distributed widely in the central nervous system and respond to classic alkaloid opiates, such as morphine and heroin, as well as to endogenous peptide ligands, which include dynorphins, enkephalins, endorphins, endomorphins, and nociceptin. Opioid receptors are coupled to inhibitory G proteins of the G(i/o) family and involved in regulating a variety of physiological functions such as pain, addiction, mood, stress, epileptic seizure, and obesity, among many others.

49-307 1.04e-15

melanin concentrating hormone receptor, member of the class A family of seven-transmembrane G protein-coupled receptors; Melanin-concentrating hormone receptor (MCHR) binds melanin concentrating hormone and is presumably involved in the neuronal regulation of food intake and energy homeostasis. Despite strong homology with somatostatin receptors, MCHR does not appear to bind somatostatin. Two MCHRs have been characterized in vertebrates, MCHR1 and MCHR2. MCHR1 is expressed in all mammals, whereas MCHR2 is only expressed in the higher order mammals, such as humans, primates, and dogs, and is not found in rodents. All GPCRs have a common structural architecture comprising of seven-transmembrane (TM) alpha-helices interconnected by three extracellular and three intracellular loops. A general feature of GPCR signaling is agonist-induced conformational changes in the receptors, leading to activation of the heterotrimeric G proteins, which consist of the guanine nucleotide-binding G-alpha subunit and the dimeric G-beta-gamma subunits. The activated G proteins then bind to and activate numerous downstream effector proteins, which generate second messengers that mediate a broad range of cellular and physiological processes.

somatostatin receptor type 4, member of the class A family of seven-transmembrane G protein-coupled receptors; G protein-coupled somatostatin receptors (SSTRs) are composed of five distinct subtypes (SSTR1-5) that display strong sequence similarity with opioid receptors. All five receptor subtypes bind the natural somatostatin (somatotropin release inhibiting factor), a polypeptide hormone that regulates a wide variety of physiological functions such as neurotransmission, cell proliferation, contractility of smooth muscle cells, and endocrine signaling as well as inhibition of the release of many secondary hormones. SSTR4 plays a critical role in mediating inflammation. Unlike other SSTRs, SSTR4 subtype is not detected in all pituitary adenomas while it is expressed in the normal human pituitary.

44-309 2.95e-14

complement component 3a anaphylatoxin chemotactic receptors, member of the class A family of seven-transmembrane G protein-coupled receptors; The anaphylatoxin receptors are a group of G-protein coupled receptors which bind anaphylatoxins; members of this group include C3a receptors and C5a receptors. Anaphylatoxins are also known as complement peptides (C3a, C4a and C5a) that are produced from the activation of the complement system cascade. These complement anaphylatoxins can trigger degranulation of endothelial cells, mast cells, or phagocytes, which induce a local inflammatory response and stimulate smooth muscle cell contraction, histamine release, and increased vascular permeability. They are potent mediators involved in chemotaxis, inflammation, and generation of cytotoxic oxygen-derived free radicals. In humans, a single receptor for C3a (C3AR1) and two receptors for C5a (C5AR1 and C5AR2, also known as C5L2 or GPR77) have been identified, but there is no known receptor for C4a.

49-307 3.34e-14

melanin concentrating hormone receptor 2, member of the class A family of seven-transmembrane G protein-coupled receptors; Melanin-concentrating hormone receptor (MCHR) binds melanin concentrating hormone and is presumably involved in the neuronal regulation of food intake and energy homeostasis. Despite strong homology with somatostatin receptors, MCHR does not appear to bind somatostatin. Two MCHRs have been characterized in vertebrates, MCHR1 and MCHR2. MCHR1 is expressed in all mammals, whereas MCHR2 is only expressed in the higher order mammals, such as humans, primates, and dogs, and is not found in rodents. All GPCRs have a common structural architecture comprising of seven-transmembrane (TM) alpha-helices interconnected by three extracellular and three intracellular loops. A general feature of GPCR signaling is agonist-induced conformational changes in the receptors, leading to activation of the heterotrimeric G proteins, which consist of the guanine nucleotide-binding G-alpha subunit and the dimeric G-beta-gamma subunits. The activated G proteins then bind to and activate numerous downstream effector proteins, which generate second messengers that mediate a broad range of cellular and physiological processes.

type 2 opsins in animals, member of the class A family of seven-transmembrane G protein-coupled receptors; This rhodopsin family represents the type 2 opsins found in vertebrates and invertebrates except sponge. Type 2 opsins primarily function as G protein coupled receptors and are responsible for vision as well as for circadian rhythm and pigment regulation. On the contrary, type 1 opsins such as bacteriorhodopsin and proteorhodopsin are found in both prokaryotic and eukaryotic microbes, functioning as light-gated ion channels, proton pumps, sensory receptors and in other unknown functions. Although these two opsin types share seven-transmembrane domain topology and a conserved lysine reside in the seventh helix, type 1 opsins do not activate G-proteins and are not evolutionarily related to type 2. Type 2 opsins can be classified into six distinct subfamilies including the vertebrate opsins/encephalopsins, the G(o) opsins, the G(s) opsins, the invertebrate G(q) opsins, the photoisomerases, and the neuropsins.

47-306 2.75e-13

bradykinin receptor B2, member of the class A family of seven-transmembrane G protein-coupled receptors; The bradykinin receptor family is a group of the seven transmembrane G-protein coupled receptors, whose endogenous ligand is the pro-inflammatory nonapeptide bradykinin that mediates various vascular and pain responses. Two major bradykinin receptor subtypes, B1 and B2, have been identified based on their pharmacological properties. The B1 receptor is rapidly induced by tissue injury and inflammation, whereas the B2 receptor is ubiquitously expressed on many tissue types. Both receptors contain three consensus sites for N-linked glycosylation in extracellular domains and couple to G(q) protein to activate phospholipase C, leading to phosphoinositide hydrolysis and intracellular calcium mobilization. They can also interact with G(i) protein to inhibit adenylate cyclase and activate the MAPK (mitogen-activated protein kinase) pathways.

complement component 5a anaphylatoxin chemotactic receptors, member of the class A family of seven-transmembrane G protein-coupled receptors; The anaphylatoxin receptors are a group of G-protein coupled receptors which bind anaphylatoxins; members of this group include C3a receptors and C5a receptors. Anaphylatoxins are also known as complement peptides (C3a, C4a and C5a) that are produced from the activation of the complement system cascade. These complement anaphylatoxins can trigger degranulation of endothelial cells, mast cells, or phagocytes, which induce a local inflammatory response and stimulate smooth muscle cell contraction, histamine release, and increased vascular permeability. They are potent mediators involved in chemotaxis, inflammation, and generation of cytotoxic oxygen-derived free radicals. In humans, a single receptor for C3a (C3AR1) and two receptors for C5a (C5AR1 and C5AR2, also known as C5L2 or GPR77) have been identified, but there is no known receptor for C4a.

47-310 5.91e-13

cholecystokinin receptors and related proteins, member of the class A family of seven-transmembrane G protein-coupled receptors; This group represents four G-protein coupled receptors that are members of the RFamide receptor family, including cholecystokinin receptors (CCK-AR and CCK-BR), orexin receptors (OXR), neuropeptide FF receptors (NPFFR), and pyroglutamylated RFamide peptide receptor (QRFPR). These RFamide receptors are activated by their endogenous peptide ligands that share a common C-terminal arginine (R) and an amidated phenylanine (F) motif. CCK-AR (type A, alimentary; also known as CCK1R) is found abundantly on pancreatic acinar cells and binds only sulfated CCK-peptides with very high affinity, whereas CCK-BR (type B, brain; also known as CCK2R), the predominant form in the brain and stomach, binds CCK or gastrin and discriminates poorly between sulfated and non-sulfated peptides. CCK is implicated in regulation of digestion, appetite control, and body weight, and is involved in neurogenesis via CCK-AR. There is some evidence to support that CCK and gastrin, via their receptors, are involved in promoting cancer development and progression, acting as growth and invasion factors. Orexins (OXs; also referred to as hypocretins) are neuropeptide hormones that regulate the sleep-wake cycle and potently influence homeostatic systems regulating appetite and feeding behavior or modulating emotional responses such as anxiety or panic. OXs are synthesized as prepro-orexin (PPO) in the hypothalamus and then proteolytically cleaved into two forms of isoforms: orexin-A (OX-A) and orexin-B (OX-B). OXA is a 33 amino-acid peptide with N-terminal pyroglutamyl residue and two intramolecular disulfide bonds, whereas OXB is a 28 amino-acid linear peptide with no disulfide bonds. OX-A binds orexin receptor 1 (OX1R) with high-affinity, but also binds with somewhat low-affinity to OX2R, and signals primarily to Gq coupling, whereas OX-B shows a strong preference for the orexin receptor 2 (OX2R) and signals through Gq or Gi/o coupling. The 26RFa, also known as QRFP (Pyroglutamylated RFamide peptide), is a 26-amino acid residue peptide that exerts similar orexigenic activity including the regulation of feeding behavior in mammals. It is the ligand for G-protein coupled receptor 103 (GPR103), which is predominantly expressed in paraventricular (PVN) and ventromedial (VMH) nuclei of the hypothalamus. GPR103 shares significant protein sequence homology with orexin receptors (OX1R and OX2R), which have recently shown to produce a neuroprotective effect in Alzheimer's disease by forming a functional heterodimer with GPR103. Neuropeptide FF (NPFF) is a mammalian octapeptide that has been implicated in a wide range of physiological functions in the brain including pain sensitivity, insulin release, food intake, memory, blood pressure, and opioid-induced tolerance and hyperalgesia. The effects of NPFF are mediated through neuropeptide FF1 and FF2 receptors (NPFF1-R and NPFF2-R) which are predominantly expressed in the brain. NPFF induces pro-nociceptive effects, mainly through the NPFF1-R, and anti-nociceptive effects, mainly through the NPFF2-R.

somatostatin-like receptor for allatostatin C, member of the class A family of seven-transmembrane G protein-coupled receptors; G protein-coupled somatostatin receptors (SSTRs) are composed of five distinct subtypes (SSTR1-5) that display strong sequence similarity with opioid receptors. All five receptor subtypes bind the natural somatostatin (somatotropin release inhibiting factor), a polypeptide hormone that regulates a wide variety of physiological functions such as neurotransmission, cell proliferation, contractility of smooth muscle cells, and endocrine signaling as well as inhibition of the release of many secondary hormones. In Drosophila melanogaster and other insects, a 15-amino-acid peptide named allatostatin C(AstC) binds the somatostatin-like receptors. Two AstC receptors have been identified in Drosophila with strong sequence homology to human somatostatin and opioid receptors.

lysophosphatidic acid receptor 5, member of the class A family of seven-transmembrane G protein-coupled receptors; Lysophosphatidic acid receptor 5 (LPAR5) is a G protein-coupled receptor that binds the bioactive lipid lysophosphatidic acid (LPA) and is involved in maintenance of human hair growth. Phylogenetic analysis of the class A GPCRs shows that LAPR5 is classified into the cluster consisting receptors that are preferentially activated by adenosine and uridine nucleotides. Although LPA6 (P2Y5) is expressed in human hair follicle cells, LPA4 and LPA5 are not. These three receptors are highly homologous and mediate an increase in intracellular cAMP production. Activation of LPAR5 is coupled to G(q) and G(12/13) proteins.

chemokine-like receptor 1, member of the class A family of seven-transmembrane G protein-coupled receptors; Chemokine receptor-like 1 (also known as Chemerin receptor 23) is a GPCR for the chemoattractant adipokine chemerin, also known as retinoic acid receptor responder protein 2 (RARRES2), and for the omega-3 fatty acid derived molecule resolvin E1. Interaction with chemerin induces activation of the MAPK and PI3K signaling pathways leading to downstream functional effects, such as a decrease in immune responses, stimulation of adipogenesis, and angiogenesis. On the other hand, resolvin E1 negatively regulates the cytokine production in macrophages by reducing the activation of MAPK1/3 and NF-kB pathways. CMKLR1 is prominently expressed in dendritic cells and macrophages.

cysteinyl leukotriene receptor 1, member of the class A family of seven-transmembrane G protein-coupled receptors; Cysteinyl leukotrienes (LTC4, LTD4, and LTE4) are the most potent inflammatory lipid mediators that play an important role in human asthma. They are synthesized in the leucocytes (cells of immune system) from arachidonic acid by the actions of 5-lipoxygenase and induce bronchial constriction through G protein-coupled receptors, CysLTR1 and CysLTR2. Activation of CysLTR1 by LTD4 induces airway smooth muscle contraction and proliferation, eosinophil migration, and damage to the lung tissue. They belong to the class A GPCR superfamily, which all have a common structural architecture comprising of seven-transmembrane (TM) alpha-helices interconnected by three extracellular and three intracellular loops. A general feature of GPCR signaling is agonist-induced conformational changes in the receptors, leading to activation of the heterotrimeric G proteins, which consist of the guanine nucleotide-binding G-alpha subunit and the dimeric G-beta-gamma subunits. The activated G proteins then bind to and activate numerous downstream effector proteins, which generate second messengers that mediate a broad range of cellular and physiological processes.

45-309 1.13e-11

N-formyl peptide receptors, member of the class A family of seven-transmembrane G protein-coupled receptors; The formyl peptide receptors (FPRs) are chemoattractant GPCRs that involved in mediating immune responses to infection. They are expressed at elevated levels on polymorphonuclear and mononuclear phagocytes. FPRs bind N-formyl peptides, which are derived from the mitochondrial proteins of ruptured host cells or invading pathogens. Activation of FPRs by N-formyl peptides such as N-formyl-Met-Leu-Phe (FMLP) triggers a signaling cascade that stimulates neutrophil accumulation, phagocytosis and superoxide production. These responses are mediated through a pertussis toxin-sensitive G(i) protein that activates a PLC-IP3-calcium signaling pathway. While FPRs are involved in host defense responses to bacterial infection, they can also suppress the immune system under certain conditions. Yet, the physiological role of the FPR family is not fully understood.

47-313 1.16e-11

GPRnna14 and related proteins, member of the class A family of seven-transmembrane G protein-coupled receptors; This group includes the orphan G-protein coupled receptor GPRnna14 found in body louse (Pediculus humanus humanus) as well as its closely related proteins of unknown function. These receptors are members of the class A rhodopsin-like G-protein coupled receptors. As an obligatory parasite of humans, the body louse is an important vector for human diseases, including epidemic typhus, relapsing fever, and trench fever. GPRnna14 shares significant sequence similarity with the members of the neurotensin receptor family. All GPCRs have a common structural architecture comprising of seven-transmembrane (TM) alpha-helices interconnected by three extracellular and three intracellular loops. A general feature of GPCR signaling is agonist-induced conformational changes in the receptors, leading to activation of the heterotrimeric G proteins, which consist of the guanine nucleotide-binding G-alpha subunit and the dimeric G-beta-gamma subunits. The activated G proteins then bind to and activate numerous downstream effector proteins, which generate second messengers that mediate a broad range of cellular and physiological processes.

cysteinyl leukotriene receptors, member of the class A family of seven-transmembrane G protein-coupled receptors; Cysteinyl leukotrienes (LTC4, LTD4, and LTE4) are the most potent inflammatory lipid mediators that play an important role in human asthma. They are synthesized in the leucocytes (cells of immune system) from arachidonic acid by the actions of 5-lipoxygenase and induce bronchial constriction through G protein-coupled receptors, CysLTR1 and CysLTR2. Activation of CysLTR1 by LTD4 induces airway smooth muscle contraction and proliferation, eosinophil migration, and damage to the lung tissue. They belong to the class A GPCR superfamily, which all have a common structural architecture comprising of seven-transmembrane (TM) alpha-helices interconnected by three extracellular and three intracellular loops. A general feature of GPCR signaling is agonist-induced conformational changes in the receptors, leading to activation of the heterotrimeric G proteins, which consist of the guanine nucleotide-binding G-alpha subunit and the dimeric G-beta-gamma subunits.

45-320 6.26e-11

gonadotropin-releasing hormone and adipokinetic hormone receptors, member of the class A family of seven-transmembrane G protein-coupled receptors; Gonadotropin-releasing hormone (GnRH) and adipokinetic hormone (AKH) receptors share strong sequence homology to each other, suggesting that they have a common evolutionary origin. GnRHR, also known as luteinizing hormone releasing hormone receptor (LHRHR), plays an central role in vertebrate reproductive function; its activation by binding to GnRH leads to the release of follicle stimulating hormone (FSH) and luteinizing hormone (LH) from the pituitary gland. Adipokinetic hormone (AKH) is a lipid-mobilizing hormone that is involved in control of insect metabolism. Generally, AKH behaves as a typical stress hormone by mobilizing lipids, carbohydrates and/or certain amino acids such as proline. Thus, it utilizes the body's energy reserves to fight the immediate stress problems and subdue processes that are less important. Although AKH is known to responsible for regulating the energy metabolism during insect flying, it is also found in insects that have lost its functional wings and predominantly walk for their locomotion. Both GnRH and AKH receptors are members of the class A of the seven-transmembrane, G-protein coupled receptor (GPCR) superfamily.

46-310 7.58e-11

G protein-coupled receptor 151, member of the class A family of seven-transmembrane G protein-coupled receptors; G-protein coupled receptor 151 (GRP151) is an orphan receptor of unknown function. Its expression is conserved in habenular axonal projections of vertebrates and may be a promising novel target for psychiatric drug development. GPR151 shows high sequence similarity with galanin receptors (GALR). GPR151 is a member of the class A rhodopsin-like GPCRs, which represent a widespread protein family that includes the light-sensitive rhodopsin as well as receptors for biogenic amines, lipids, nucleotides, odorants, peptide hormones, and a variety of other ligands. All GPCRs have a common structural architecture comprising of seven-transmembrane (TM) alpha-helices interconnected by three extracellular and three intracellular loops. A general feature of GPCR signaling is agonist-induced conformational changes in the receptors, leading to activation of the heterotrimeric G proteins, which consist of the guanine nucleotide-binding G-alpha subunit and the dimeric G-beta-gamma subunits. The activated G proteins then bind to and activate numerous downstream effector proteins, which generate second messengers that mediate a broad range of cellular and physiological processes.

47-307 2.56e-10

somatostatin receptor type 5, member of the class A family of seven-transmembrane G protein-coupled receptors; G protein-coupled somatostatin receptors (SSTRs) are composed of five distinct subtypes (SSTR1-5) that display strong sequence similarity with opioid receptors. All five receptor subtypes bind the natural somatostatin (somatotropin release inhibiting factor), a polypeptide hormone that regulates a wide variety of physiological functions such as neurotransmission, cell proliferation, contractility of smooth muscle cells, and endocrine signaling as well as inhibition of the release of many secondary hormones. SSTR5 is coupled to inward rectifying K channels and phospholipase C, and plays critical roles in growth hormone and insulin secretion. SSTR5 acts as a negative regulator of PDX-1 (pancreatic and duodenal homeobox-1) expression, which is a conserved homeodomain-containing beta cell-specific transcription factor essentially involved in pancreatic development, among many other functions.

46-310 2.89e-10

urotensin-II receptor, member of the class A family of seven-transmembrane G protein-coupled receptors; The urotensin-II receptor (UII-R, also known as the hypocretin receptor) is a member of the class A rhodopsin-like G-protein coupled receptors, which binds the peptide hormone urotensin-II. Urotensin II (UII) is a vasoactive somatostatin-like or cortistatin-like peptide hormone. However, despite the apparent structural similarity to these peptide hormones, they are not homologous to UII. Urotensin II was first identified in fish spinal cord, but later found in humans and other mammals. In fish, UII is secreted at the back part of the spinal cord, in a neurosecretory centre called uroneurapophysa, and is involved in the regulation of the renal and cardiovascular systems. In mammals, urotensin II is the most potent mammalian vasoconstrictor identified to date and causes contraction of arterial blood vessels, including the thoracic aorta. The urotensin II receptor is a rhodopsin-like G-protein coupled receptor, which binds urotensin-II. The receptor was previously known as GPR14, or sensory epithelial neuropeptide-like receptor (SENR). The UII receptor is expressed in the CNS (cerebellum and spinal cord), skeletal muscle, pancreas, heart, endothelium and vascular smooth muscle. It is involved in the pathophysiological control of cardiovascular function and may also influence CNS and endocrine functions. Binding of urotensin II to the receptor leads to activation of phospholipase C, through coupling to G(q/11) family proteins. The resulting increase in intracellular calcium may cause the contraction of vascular smooth muscle.

45-306 4.61e-10

vasopressin receptors and its related G protein-coupled receptors, member of the class A family of seven-transmembrane G protein-coupled receptors; Members of this group form a subfamily within the class A G-protein coupled receptors (GPCRs), which includes the vasopressin and oxytocin receptors, the gonadotropin-releasing hormone receptors (GnRHRs), the neuropeptide S receptor (NPSR), and orphan GPR150. These receptors share significant sequence homology with each other, suggesting that they have a common evolutionary origin. Vasopressin, also known as arginine vasopressin or anti-diuretic hormone, is a neuropeptide synthesized in the hypothalamus. The actions of vasopressin are mediated by the interaction of this hormone with three tissue-specific subtypes: V1AR, V1BR, and V2R. Although vasopressin differs from oxytocin by only two amino acids, they have divergent physiological functions. Vasopressin is involved in regulating osmotic and cardiovascular homeostasis, whereas oxytocin plays an important role in the uterus during childbirth and in lactation. GnRHR, also known as luteinizing hormone releasing hormone receptor (LHRHR), plays an central role in vertebrate reproductive function; its activation by binding to GnRH leads to the release of follicle stimulating hormone (FSH) and luteinizing hormone (LH) from the pituitary gland. Neuropeptide S (NPS) promotes arousal and anxiolytic-like effects by activating its cognate receptor NPSR. NPSR has also been associated with asthma and allergy. GPR150 is an orphan receptor closely related to the oxytocin and vasopressin receptors.

galanin receptor and related proteins, member of the class A family of seven-transmembrane G protein-coupled receptors; This subfamily includes G-protein coupled galanin receptors, kisspeptin receptor and allatostatin-A receptor (AstA-R) in insects. These receptors, which are members of the class A of seven transmembrane GPCRs, share a high degree of sequence homology among themselves. The galanin receptors bind galanin, a neuropeptide that is widely expressed in the brain, peripheral tissues, and endocrine glands. Galanin is implicated in numerous neurological and psychiatric diseases including Alzheimer's disease, eating disorders, and epilepsy, among many others. KiSS1-derived peptide receptor (also known as GPR54 or kisspeptin receptor) binds the peptide hormone kisspeptin (metastin), which encoded by the metastasis suppressor gene (KISS1) expressed in various endocrine and reproductive tissues. AstA-R is a G-protein coupled receptor that binds allatostatin A. Three distinct types of allatostatin have been identified in the insects and crustaceans: AstA, AstB, and AstC. They both inhibit the biosynthesis of juvenile hormone and exert an inhibitory influence on food intake. Therefore, allatostatins are considered as potential targets for insect control.

G protein-coupled receptor 182, member of the class A family of seven-transmembrane G protein-coupled receptors; GPR182 is an orphan G-protein coupled receptor that belongs to the class A of seven-transmembrane GPCR superfamily. When GPR182 gene was first cloned, it was proposed to encode an adrenomedullin receptor. However when the corresponding protein was expressed, it was found not to respond to adrenomedullin (ADM). All GPCRs have a common structural architecture comprising of seven-transmembrane (TM) alpha-helices interconnected by three extracellular and three intracellular loops. A general feature of GPCR signaling is agonist-induced conformational changes in the receptors, leading to activation of the heterotrimeric G proteins, which consist of the guanine nucleotide-binding G-alpha subunit and the dimeric G-beta-gamma subunits. The activated G proteins then bind to and activate numerous downstream effector proteins, which generate second messengers that mediate a broad range of cellular and physiological processes.

50-306 2.02e-09

prostaglandin D2 receptor, member of the class A family of seven-transmembrane G protein-coupled receptors; Prostaglandin D2 receptor, also known as CRTH2, is a chemoattractant G-protein coupled receptor expressed on T helper type 2 cells that binds prostaglandin D2 (PGD2). PGD2 functions as a mast cell-derived mediator to trigger asthmatic responses and also causes vasodilation. PGD2 exerts its inflammatory effects by binding to two G-protein coupled receptors, the D-type prostanoid receptor (DP) and PD2R2 (CRTH2). PD2R2 couples to the G protein G(i/o) type which leads to a reduction in intracellular cAMP levels and an increase in intracellular calcium. PD2R2 is involved in mediating chemotaxis of Th2 cells, eosinophils, and basophils generated during allergic inflammatory processes. CRTH2 (PD2R2), but not DP receptor, undergoes agonist-induced internalization which is one of key processes that regulates the signaling of the GPCR.

45-304 3.41e-09

adipokinetic hormone receptor, member of the class A family of seven-transmembrane G protein-coupled receptors; Adipokinetic hormone (AKH) is a lipid-mobilizing hormone that is involved in control of insect metabolism. Generally, AKH behaves as a typical stress hormone by mobilizing lipids, carbohydrates and/or certain amino acids such as proline. Thus, it utilizes the body's energy reserves to fight the immediate stress problems and subdue processes that are less important. Although AKH is known to responsible for regulating the energy metabolism during insect flight, it is also found in insects that have lost its functional wings and predominantly walk for their locomotion. AKH is structurally related to the mammalian gonadotropin-releasing hormone (GnRH) and they share a common ancestor. Both GnRH and AKH receptors are members of the class A of the seven-transmembrane, G-protein coupled receptor (GPCR) superfamily.

galanin receptor subtype 1, member of the class A family of seven-transmembrane G protein-coupled receptors; The G protein-coupled galanin receptors bind galanin, a neuropeptide that is widely expressed in the brain, peripheral tissues, and endocrine glands. Three receptors subtypes have been so far identified: GAL1, GAL2, and GAL3. The specific functions of each subtype remains mostly unknown, although galanin is thought to be involved in a variety of neuronal functions such as hormone release and food intake. Galanin is implicated in numerous neurological and psychiatric diseases including Alzheimer's disease, depression, eating disorders, epilepsy and stroke, among many others.

50-307 5.68e-09

somatostatin receptor type 1, member of the class A family of seven-transmembrane G protein-coupled receptors; G protein-coupled somatostatin receptors (SSTRs) are composed of five distinct subtypes (SSTR1-5) that display strong sequence similarity with opioid receptors. All five receptor subtypes bind the natural somatostatin (somatotropin release inhibiting factor), a polypeptide hormone that regulates a wide variety of physiological functions such as neurotransmission, cell proliferation, contractility of smooth muscle cells, and endocrine signaling as well as inhibition of the release of many secondary hormones. SSTR1 is coupled to a Na/H exchanger, voltage-dependent calcium channels, and AMPA/kainate glutamate channels. SSTR1 is expressed in the normal human pituitary and in nearly half of all pituitary adenoma subtypes.

46-309 9.71e-09

neuropeptide Y receptor type 6, member of the class A family of seven-transmembrane G protein-coupled receptors; NPY is a 36-amino acid peptide neurotransmitter with a C-terminal tyrosine amide residue that is widely distributed in the brain and the autonomic nervous system of many mammalian species. NPY exerts its functions through five, G-protein coupled receptor subtypes including NPY1R, NPY2R, NPY4R, NPY5R, and NPY6R; however, NPY6R is not functional in humans. NYP receptors are also activated by its two other family members, peptide YY (PYY) and pancreatic polypeptide (PP). They typically couple to G(i) or G(o) proteins, which leads to a decrease in adenylate cyclase activity, thereby decreasing intracellular cAMP levels, and are involved in diverse physiological roles including appetite regulation, circadian rhythm, and anxiety.

G protein-coupled receptor 1 for chemerin, member of the class A family of seven-transmembrane G protein-coupled receptors; G-protein coupled receptor 1 (GPR1) belongs to the class A of the seven transmembrane domain receptors. This is an orphan receptor that can be activated by the leukocyte chemoattractant chemerin, thereby suggesting that some of the anti-inflammatory actions of chemerin may be mediated through GPR1. GPR1 is most closely related to another chemerin receptor CMKLR1. In an in-vitro study, GPR1 has been shown to act as a co-receptor to allow replication of HIV viruses.

45-304 1.99e-08

invertebrate gonadotropin-releasing hormone receptors, member of the class A family of seven-transmembrane G protein-coupled receptors; GnRHR, also known as luteinizing hormone releasing hormone receptor (LHRHR), plays an central role in vertebrate reproductive function; its activation by binding to GnRH leads to the release of follicle stimulating hormone (FSH) and luteinizing hormone (LH) from the pituitary gland. GnRHR is expressed predominantly in the gonadotrope membrane of the anterior pituitary as well as found in numerous extrapituitary tissues including lymphocytes, breast, ovary, prostate, and cancer cell lines. There are at least two types of GnRH receptors, GnRHR1 and GnRHR2, which couple primarily to G proteins of the Gq/11 family. GnRHR is closely related to the adipokinetic hormone receptor (AKH), which binds to a lipid-mobilizing hormone that is involved in control of insect metabolism. They share a common ancestor and are members of the class A of the seven-transmembrane, G-protein coupled receptor (GPCR) superfamily.

lysophosphatidic acid receptor 6, member of the class A family of seven-transmembrane G protein-coupled receptors; Lysophosphatidic acid receptor 6 (LPAR6), also known as P2Y5, is a G(i), G(12/13) G protein-coupled receptor that is activated by the bioactive lipid lysophosphatidic acid (LPA), which is released by activated platelets and constitutively present in serum. LPAR6 plays an important role in maintenance of human hair growth. Thus, mutations in the receptor are responsible for both autosomal recessive wooly hair and hypotrichosis. Phylogenetic analysis of the class A GPCRs shows that LAPR6 (P2Y5) is classified into the cluster consisting of receptors that are preferentially activated by adenosine and uridine nucleotides. Although LPA6 (P2Y5) is expressed in human hair follicle cells, LPA4 and LPA5 are not. These three receptors are highly homologous and mediate an increase in intracellular cAMP production.

bombesin receptor subtype 3, member of the class A family of seven-transmembrane G protein-coupled receptors; BRS-3 is classified as an orphan receptor and belongs to the bombesin subfamily of G-protein coupled receptors, whose members also include neuromedin B receptor (NMBR) and gastrin-releasing peptide receptor (GRPR). Bombesin is a tetradecapeptide, originally isolated from frog skin. Mammalian bombesin-related peptides are widely distributed in the gastrointestinal and central nervous systems. The bombesin family receptors couple primarily to the G proteins of G(q/11) family. BRS-3 interacts with known naturally-occurring bombesin-related peptides with low affinity; however, no endogenous high-affinity ligand to the receptor has been identified. BRS-3 is suggested to play a role in sperm cell division and maturation.

44-309 2.93e-08

G protein-coupled receptor 84 and similar proteins, member of the class A family of seven-transmembrane G protein-coupled receptors; GPR84, also known as the inflammation-related G-Protein coupled receptor EX33, is a receptor for medium-chain free fatty acid (FFA) with carbon chain lengths of C9 to C14. Among these medium-chain FFAs, capric acid (C10:0), undecanoic acid (C11:0), and lauric acid (C12:0) are the most potent endogenous agonists of GPR84, whereas short-chain and long-chain saturated and unsaturated FFAs do not activate this receptor. GPR84 contains a [G/N]RY-motif instead of the highly conserved Asp-Arg-Tyr (DRY) motif found in the third transmembrane helix (TM3) of the rhodopsin-like class A receptors and important for efficient G protein-coupled signal transduction. All GPCRs have a common structural architecture comprising of seven-transmembrane (TM) alpha-helices interconnected by three extracellular and three intracellular loops. A general feature of GPCR signaling is agonist-induced conformational changes in the receptors, which then activate the heterotrimeric G proteins. In the case of GPR84, activation of the receptor couples to a pertussis toxin sensitive G(i/o)-protein pathway. GPR84 knockout mice showed increased Th2 cytokine production including IL-4, IL-5, and IL-13 compared to wild-type mice. It has been also shown that activation of GPR84 augments lipopolysaccharide-stimulated IL-8 production in polymorphonuclear leukocytes and TNF-alpha production in macrophages, suggesting that GPR84 may function as a proinflammatory receptor.

33-304 3.03e-08

P2Y purinoceptor 11, member of the class A family of seven-transmembrane G protein-coupled receptors; P2Y11 belongs to the P2Y receptor family of purinergic G-protein coupled receptors. The activation of P2Y11 is a major pathway of macrophage activation that leads to the release of cytokines. The P2Y receptor family is composed of eight subtypes, which are activated by naturally occurring extracellular nucleotides such as ATP, ADP, UTP, UDP, and UDP-glucose. These eight receptors are ubiquitous in human tissues and can be further classified into two subfamilies based on sequence homology and second messenger coupling: a subfamily of five P2Y1-like receptors (P2Y1, P2Y2, P2Y4, P2Y6, and P2Y11Rs) that are coupled to G(q) protein to activate phospholipase C (PLC) and a second subfamily of three P2Y12-like receptors (P2Y12, P2YR13, and P2Y14Rs) that are coupled to G(i) protein to inhibit adenylate cyclase. Several cloned subtypes, such as P2Y3, P2Y5, and P2Y7-10, are not functional mammalian nucleotide receptors. The native agonists for P2Y receptors are: ATP (P2Y2, P2Y12), ADP (P2Y1, P2Y12, and P2Y13), UTP (P2Y2, P2Y4), UDP (P2Y6, P2Y14), and UDP-glucose (P2Y14).

47-304 4.00e-08

cysteinyl leukotriene receptor 2, member of the class A family of seven-transmembrane G protein-coupled receptors; Cysteinyl leukotrienes (LTC4, LTD4, and LTE4) are the most potent inflammatory lipid mediators that play an important role in human asthma. They are synthesized in the leucocytes (cells of immune system) from arachidonic acid by the actions of 5-lipoxygenase and induce bronchial constriction through G protein-coupled receptors, CysLTR1 and CysLTR2. Activation of CysLTR1 by LTD4 induces airway smooth muscle contraction and proliferation, eosinophil migration, and damage to the lung tissue. They belong to the class A GPCR superfamily, which all have a common structural architecture comprising of seven-transmembrane (TM) alpha-helices interconnected by three extracellular and three intracellular loops. A general feature of GPCR signaling is agonist-induced conformational changes in the receptors, leading to activation of the heterotrimeric G proteins, which consist of the guanine nucleotide-binding G-alpha subunit and the dimeric G-beta-gamma subunits. The activated G proteins then bind to and activate numerous downstream effector proteins, which generate second messengers that mediate a broad range of cellular and physiological processes.

47-304 5.73e-08

protease-activated receptors, member of the class A family of seven-transmembrane G protein-coupled receptors; This subfamily includes purinergic receptor P2Y8 and protease-activated receptors. P2Y8 (or P2RY8) expression is often increased in leukemia patients, and it plays a role in the pathogenesis of acute leukemia. P2Y8 is phylogenetically closely related to the protease-activated receptors (PARs), which are activated by serine proteases such as thrombin, trypsin, and tryptase. These proteases cleave the extracellular domain of the receptor to form a new N-terminus, which in turn functions as a tethered ligand. The newly-formed tethered ligand binds intramolecularly to activate the receptor and triggers G-protein binding and intracellular signaling. Four different types of the protease-activated receptors have been identified (PAR1-4) and are predominantly expressed in platelets. PAR1, PAR3, and PAR4 are activated by thrombin, whereas PAR2 is activated by trypsin. The PARs are known to couple with several G-proteins including Gi (cAMP inhibitory), G12/13 (Rho and Ras activation), and Gq (calcium signaling) to activate downstream signaling messengers which induces numerous cellular and physiological effects.

leukotriene B4 receptors, member of the class A family of seven-transmembrane G protein-coupled receptors; Leukotriene B4 (LTB4), a metabolite of arachidonic acid, is a powerful chemotactic activator for granulocytes and macrophages. Two receptors for LTB4 have been identified: a high-affinity receptor (LTB4R1 or BLT1) and a low-affinity receptor (TB4R2 or BLT2). Both BLT1 and BLT2 receptors belong to the rhodopsin-like G-protein coupled receptor superfamily and primarily couple to G(i) proteins, which lead to chemotaxis, calcium mobilization, and inhibition of adenylate cyclase. In some cells, they can also couple to the G(q)-like protein, G16, and activate phospholipase C. LTB4 is involved in mediating inflammatory processes, immune responses, and host defense against infection. Studies have shown that LTB4 stimulates leukocyte extravasation, neutrophil degranulation, lysozyme release, and reactive oxygen species generation.

46-306 1.06e-07

orphan receptor GPR33, member of the class A family of seven-transmembrane G protein-coupled receptors; G-protein coupled receptor GPR33, an orphan member of the chemokine-like receptor family, was originally identified as a pseudogene in humans as well as in several apes and rodent species. Although the intact GPR33 allele is still present in a small fraction of the human population, the human GPR33 contains a premature stop codon. The amino acid sequence of GPR33 shares a high degree of sequence identity with the members of the chemokine and chemoattractant receptors that control leukocyte chemotaxis.

49-312 1.59e-07

neuropeptide B/W receptors, member of the class A family of seven-transmembrane G protein-coupled receptors; Neuropeptide B/W receptor 1 and 2 are members of the class A G-protein coupled receptors that bind the neuropeptides B and W, respectively. NPBWR1 (previously known as GPR7) is expressed predominantly in cerebellum and frontal cortex, while NPBWR2 (previously known as GPR8) is located mostly in the frontal cortex and is present in human, but not in rat and mice. These receptors are suggested to be involved in the regulation of food intake, neuroendocrine function, and modulation of inflammatory pain, among many others. All GPCRs have a common structural architecture comprising of seven-transmembrane (TM) alpha-helices interconnected by three extracellular and three intracellular loops. A general feature of GPCR signaling is agonist-induced conformational changes in the receptors, leading to activation of the heterotrimeric G proteins, which consist of the guanine nucleotide-binding G-alpha subunit and the dimeric G-beta-gamma subunits. The activated G proteins then bind to and activate numerous downstream effector proteins, which generate second messengers that mediate a broad range of cellular and physiological processes.

47-310 1.61e-07

neuromedin-K receptor, member of the class A family of seven-transmembrane G protein-coupled receptors; The neuromedin-K receptor (NKR), also known as tachykinin receptor 3 (TACR3) or neurokinin B receptor or NK3R, is a G-protein coupled receptor that specifically binds to neurokinin B. The tachykinins (TKs) act as excitatory transmitters on neurons and cells in the gastrointestinal tract. The TKs are characterized by a common five-amino acid C-terminal sequence, Phe-X-Gly-Leu-Met-NH2, where X is a hydrophobic residue. The three major mammalian tachykinins are substance P (SP), neurokinin A (NKA), and neurokinin B (NKB). The physiological actions of tachykinins are mediated through three types of receptors: neurokinin receptor type 1 (NK1R), NK2R, and NK3R. NK3R is activated by its high-affinity ligand, NKB, which is primarily involved in the central nervous system and plays a critical role in the regulation of gonadotropin hormone release and the onset of puberty.

43-244 1.77e-07

ecdysis-triggering hormone receptors, member of the class A family of seven-transmembrane G protein-coupled receptors; This subgroup represents the ecdysis-triggering hormone receptors found in insects, which are members of the class A family of seven-transmembrane G-protein coupled receptors. Ecdysis-triggering hormones are vital regulatory signals that govern the stereotypic physiological sequence leading to cuticle shedding in insects. Thus, the ETH signaling system has been a target for the design of more sophisticated insect-selective pest control strategies. Two subtypes of ecdysis-triggering hormone receptor were identified in Drosophila melanogaster. Blood-borne ecdysis-triggering hormone (ETH) activates the behavioral sequence through direct actions on the central nervous system. In insects, ecdysis is thought to be controlled by the interaction between peptide hormones; in particular between ecdysis-triggering hormone (ETH) from the periphery and eclosion hormone (EH) and crustacean cardioactive peptide (CCAP) from the central nervous system. All GPCRs have a common structural architecture comprising of seven-transmembrane (TM) alpha-helices interconnected by three extracellular and three intracellular loops. A general feature of GPCR signaling is agonist-induced conformational changes in the receptors, leading to activation of the heterotrimeric G proteins, which consist of the guanine nucleotide-binding G-alpha subunit and the dimeric G-beta-gamma subunits. The activated G proteins then bind to and activate numerous downstream effector proteins, which generate second messengers that mediate a broad range of cellular and physiological processes.

neuropeptide Y receptor-like found in insect and related proteins, member of the class A family of seven-transmembrane G protein-coupled receptors; This subgroup includes a novel G protein-coupled receptor (also known as PR4 receptor) from Drosophila melanogaster, which can be activated by the members of the neuropeptide Y (NPY) family, including NPY, peptide YY (PYY) and pancreatic polypeptide (PP), when expressed in Xenopus oocytes. These homologous peptides of 36-amino acids in length contain a hairpin-like structural motif, which referred to as the pancreatic polypeptide fold, and function as gastrointestinal hormones and neurotransmitters. The PR4 receptor also shares strong sequence homology to the mammalian tachykinin receptors (NK1R, NK2R, and NK3R), whose endogenous ligands are substance P (SP), neurokinin A (NKA), and neurokinin B (NKB), respectively. The tachykinins function as excitatory transmitters on neurons and cells in the gastrointestinal tract.

2-oxoglutarate receptor 1, member of the class A family of seven-transmembrane G protein-coupled receptors; 2-oxoglutarate receptor 1 (OXGR1) is also known as GPR80, GPR99, or P2Y15. OXGR1 functions as a receptor for alpha-ketoglutarate, a citric acid cycle intermediate, and acts exclusively through a G(q)-dependent pathway. OXGR1 belongs to the class A GPCR superfamily and is phylogenetically related to the purinergic P2Y1-like receptor subfamily, whose members are coupled to G(q) protein to activate phospholipase C (PLC). OXGR1 has also been reported as a potential third cysteinyl leukotriene receptor with specificity for leukotriene E4.

34-307 3.33e-07

succinate receptor 1, member of the class A family of seven-transmembrane G protein-coupled receptors; Succinate receptor (SUCNR1) GPR91 exclusively couples to G(i) protein to inhibit cAMP production and also activates PLC-beta to increase intracellular calcium concentrations in an inositol phosphate dependent mechanism. Succinate, an intermediate molecule of the citric cycle, is shown to cause cardiac hypertrophy via GPR91 activation. Furthermore, succinate-induced GPR91 activation is involved in the regulation of renin-angiotensin system and is suggested to play an important role in the development of renovascular hypertension and diabetic nephropathy. SUCNR1 belongs to the class A GPCR superfamily and is phylogenetically related to the purinergic P2Y1-like receptor subfamily, whose members are coupled to G(q) protein to activate phospholipase C (PLC).

somatostatin receptor type 2, member of the class A family of seven-transmembrane G protein-coupled receptors; G protein-coupled somatostatin receptors (SSTRs), which display strong sequence similarity with opioid receptors, binds somatostatin, a polypeptide hormone that regulates a wide variety of physiological such as neurotransmission, endocrine secretion, cell proliferation, and smooth muscle contractility. SSTRs are composed of five distinct subtypes (SSTR1-5) which are encoded by separate genes on different chromosomes. SSTR2 plays critical roles in growth hormone secretion, glucagon secretion, and immune responses. SSTR2 is expressed in the normal human pituitary and in nearly all pituitary growth hormone adenomas.

44-310 3.98e-07

neurotensin receptors and related G protein-coupled receptors, member of the class A family of seven-transmembrane G protein-coupled receptors; This subfamily includes the neurotensin receptors and related G-protein coupled receptors, including neuromedin U receptors, growth hormone secretagogue receptor, motilin receptor, the putative GPR39 and the capa receptors from insects. These receptors all bind peptide hormones with diverse physiological effects. All GPCRs have a common structural architecture comprising of seven-transmembrane (TM) alpha-helices interconnected by three extracellular and three intracellular loops. A general feature of GPCR signaling is agonist-induced conformational changes in the receptors, leading to activation of the heterotrimeric G proteins, which consist of the guanine nucleotide-binding G-alpha subunit and the dimeric G-beta-gamma subunits. The activated G proteins then bind to and activate numerous downstream effector proteins, which generate second messengers that mediate a broad range of cellular and physiological processes.

45-308 4.22e-07

neuropeptide Y receptor type 4, member of the class A family of seven-transmembrane G protein-coupled receptors; NPY is a 36-amino acid peptide neurotransmitter with a C-terminal tyrosine amide residue that is widely distributed in the brain and the autonomic nervous system of many mammalian species. NPY exerts its functions through five, G-protein coupled receptor subtypes including NPY1R, NPY2R, NPY4R, NPY5R, and NPY6R; however, NPY6R is not functional in humans. NYP receptors are also activated by its two other family members, peptide YY (PYY) and pancreatic polypeptide (PP). They typically couple to G(i) or G(o) proteins, which leads to a decrease in adenylate cyclase activity, thereby decreasing intracellular cAMP levels, and are involved in diverse physiological roles including appetite regulation, circadian rhythm, and anxiety.

neuropeptide FF receptors, member of the class A family of seven-transmembrane G protein-coupled receptors; Neuropeptide FF (NPFF) is a mammalian octapeptide that belongs to a family of neuropeptides containing an RF-amide motif at their C-terminus that have been implicated in a wide range of physiological functions in the brain including pain sensitivity, insulin release, food intake, memory, blood pressure, and opioid-induced tolerance and hyperalgesia. The effects of these peptides are mediated through neuropeptide FF1 and FF2 receptors (NPFF1-R and NPFF2-R) which are predominantly expressed in the brain. NPFF induces pro-nociceptive effects, mainly through the NPFF1-R, and anti-nociceptive effects, mainly through the NPFF2-R. NPFF has been shown to inhibit adenylate cyclase via the Gi protein coupled to NPFF1-R.

Mammalian melanopsins are expressed only in the inner retina, whereas non-mammalian vertebrate melanopsins are localized in various extra-retinal tissues such as iris, brain, pineal gland, and skin. The outer photoreceptors (R1-R6) are the insect Drosophila equivalent to the vertebrate rods and are responsible for image formation and motion detection. The invertebrate G(q) opsins includes the arthropod and mollusk visual opsins as well as invertebrate melanopsins, which are also found in vertebrates. Arthropods possess color vision by the use of multiple opsins sensitive to different light wavelengths. Members of this subfamily belong to the class A of the G protein-coupled receptors and have seven-transmembrane (TM) alpha-helices interconnected by three extracellular and three intracellular loops.

47-308 8.22e-07

tachykinin receptors and related receptors, member of the class A family of seven-transmembrane G protein-coupled receptors; This group includes the neurokinin/tachykinin receptors and its closely related receptors such as orphan GPR83 and leucokinin-like peptide receptor. The tachykinins are widely distributed throughout the mammalian central and peripheral nervous systems and act as excitatory transmitters on neurons and cells in the gastrointestinal tract. The TKs are characterized by a common five-amino acid C-terminal sequence, Phe-X-Gly-Leu-Met-NH2, where X is a hydrophobic residue. The three major mammalian tachykinins are substance P (SP), neurokinin A (NKA), and neurokinin B (NKB). The physiological actions of tachykinins are mediated through three types of receptors: neurokinin receptor type 1 (NK1R), NK2R, and NK3R. SP is a high-affinity endogenous ligand for NK1R, which interacts with the Gq protein and activates phospholipase C, leading to elevation of intracellular calcium. NK2R is a high-affinity receptor for NKA, the tachykinin neuropeptide substance K. SP and NKA are found in the enteric nervous system and mediate in the regulation of gastrointestinal motility, secretion, vascular permeability, and pain perception. NK3R is activated by its high-affinity ligand, NKB, which is primarily involved in the central nervous system and plays a critical role in the regulation of gonadotropin hormone release and the onset of puberty.

47-314 9.28e-07

P2Y purinoceptor 1-like; P2Y1-like is an uncharacterized group that is phylogenetically related to a family of purinergic G protein-coupled receptors. The P2Y receptor family is composed of eight subtypes, which are activated by naturally occurring extracellular nucleotides such as ATP, ADP, UTP, UDP, and UDP-glucose. These eight receptors are ubiquitous in human tissues and can be further classified into two subfamilies based on sequence homology and second messenger coupling: a subfamily of five P2Y1-like receptors (P2Y1, P2Y2, P2Y4, P2Y6, and P2Y11Rs) that are coupled to G(q) protein to activate phospholipase C (PLC) and a second subfamily of three P2Y12-like receptors (P2Y12, P2YR13, and P2Y14Rs) that are coupled to G(i) protein to inhibit adenylate cyclase. Several cloned subtypes, such as P2Y3, P2Y5, and P2Y7-10, are not functional mammalian nucleotide receptors. The native agonists for P2Y receptors are: ATP (P2Y2, P2Y12), ADP (P2Y1, P2Y12, and P2Y13), UTP (P2Y2, P2Y4), UDP (P2Y6, P2Y14), and UDP-glucose (P2Y14).

neuropsin (Opsin-5), member of the class A family of seven-transmembrane G protein-coupled receptors; Neuropsin, also known as Opsin-5, is a photoreceptor protein expressed in the retina, brain, testes, and spinal cord. Neuropsin belongs to the type 2 opsin family of the class A G-protein coupled receptors. Mammalian neuropsin activates Gi protein-mediated photo-transduction pathway in a UV-dependent manner, whereas, in non-mammalian vertebrates, neuropsin is involved in regulating the photoperiodic control of seasonal reproduction in birds such as quail. As with other opsins, it may also act as a retinal photoisomerase.

G protein-coupled receptor 83, member of the class A family of seven-transmembrane G protein-coupled receptors; GPR83, also known as GPR72, is widely expressed in the brain, including hypothalamic nuclei which is involved in regulating energy balance and food intake. The hypothalamic expression of GPR83 is tightly regulated in response to nutrient availability and is decreased in obese mice. A recent study suggests that GPR83 has a critical role in the regulation of systemic energy metabolism via ghrelin-dependent and ghrelin-independent mechanisms. GPR83 shares a significant amino acid sequence identity with the tachykinin receptors, however its endogenous ligand is unknown.

50-304 3.29e-06

leukotriene B4 receptor subtype 2 (LTB4R2 or BLT2), member of the class A family of seven-transmembrane G protein-coupled receptors; Leukotriene B4 (LTB4), a metabolite of arachidonic acid, is a powerful chemotactic activator for granulocytes and macrophages. Two receptors for LTB4 have been identified: a high-affinity receptor (LTB4R1 or BLT1) and a low-affinity receptor (TB4R2 or BLT2). Both BLT1 and BLT2 receptors belong to the rhodopsin-like G-protein coupled receptor superfamily and primarily couple to G(i) proteins, which lead to chemotaxis, calcium mobilization, and inhibition of adenylate cyclase. In some cells, they can also couple to the Gq-like protein, G16, and activate phospholipase C. LTB4 is involved in mediating inflammatory processes, immune responses, and host defense against infection. Studies have shown that LTB4 stimulates leukocyte extravasation, neutrophil degranulation, lysozyme release, and reactive oxygen species generation.

47-315 6.04e-06

bombesin receptor subfamily, member of the class A family of seven-transmembrane G protein-coupled receptors; This bombesin subfamily of G-protein coupled receptors consists of neuromedin B receptor (NMBR), gastrin-releasing peptide receptor (GRPR), and bombesin receptor subtype 3 (BRS-3). Bombesin is a tetradecapeptide, originally isolated from frog skin. Mammalian bombesin-related peptides are widely distributed in the gastrointestinal and central nervous systems. The bombesin family receptors couple mainly to the G proteins of G(q/11) family. NMBR functions as the receptor for the neuropeptide neuromedin B, a potent mitogen and growth factor for normal and cancerous lung and for gastrointestinal epithelial tissues. Gastrin-releasing peptide is an endogenous ligand for GRPR and shares high sequence homology with NMB in the C-terminal region. Both NMB and GRP possess bombesin-like biochemical properties. BRS-3 is classified as an orphan receptor and suggested to play a role in sperm cell division and maturation. BRS-3 interacts with known naturally-occurring bombesin-related peptides with low affinity; however, no endogenous high-affinity ligand to the receptor has been identified. The bombesin receptor family belongs to the seven transmembrane rhodopsin-like G-protein coupled receptors (class A GPCRs), which perceive extracellular signals and transduce them to guanine nucleotide-binding (G) proteins.

47-169 7.19e-06

super conserved receptor expressed in brain and related proteins, member of the class A family of seven-transmembrane G protein-coupled receptors; The SREB (super conserved receptor expressed in brain) subfamily consists of at least three members, named SREB1 (GPR27), SREB2 (GPR85), and SREB3 (GPR173). They are very highly conserved G protein-coupled receptors throughout vertebrate evolution, however no endogenous ligands have yet been identified. SREB2 is greatly expressed in brain regions involved in psychiatric disorders and cognition, such as the hippocampal dentate gyrus. Genetic studies in both humans and mice have shown that SREB2 influences brain size and negatively regulates hippocampal adult neurogenesis and neurogenesis-dependent cognitive function, all of which are suggesting a potential link between SREB2 and schizophrenia. All three SREB genes are highly expressed in differentiated hippocampal neural stem cells. Furthermore, all GPCRs have a common structural architecture comprising of seven-transmembrane (TM) alpha-helices interconnected by three extracellular and three intracellular loops. A general feature of GPCR signaling is agonist-induced conformational changes in the receptors, leading to activation of the heterotrimeric G proteins, which consist of the guanine nucleotide-binding G-alpha subunit and the dimeric G-beta-gamma subunits. The activated G proteins then bind to and activate numerous downstream effector proteins, which generate second messengers that mediate a broad range of cellular and physiological processes.

41-308 9.73e-06

pyroglutamylated RFamide peptide receptor, member of the class A family of seven-transmembrane G protein-coupled receptors; 26RFa, also known as QRFP (Pyroglutamylated RFamide peptide), is a 26-amino acid residue peptide that belongs to a family of neuropeptides containing an Arg-Phe-NH2 (RFamide) motif at its C-terminus. 26Rfa/QRFP exerts similar orexigenic activity including the regulation of feeding behavior in mammals. It is the ligand for G-protein coupled receptor 103 (GPR103), which is predominantly expressed in paraventricular (PVN) and ventromedial (VMH) nuclei of the hypothalamus. GPR103 shares significant protein sequence homology with orexin receptors (OX1R and OX2R), which have recently shown to produce a neuroprotective effect in Alzheimer's disease by forming a functional heterodimer with GPR103.

45-315 1.07e-05

tachykinin receptor and closely related proteins, member of the class A family of seven-transmembrane G protein-coupled receptors; This subfamily includes G-protein coupled receptors for a variety of neuropeptides of the tachykinin (TK) family as well as closely related receptors. The tachykinins are widely distributed throughout the mammalian central and peripheral nervous systems and act as excitatory transmitters on neurons and cells in the gastrointestinal tract. The TKs are characterized by a common five-amino acid C-terminal sequence, Phe-X-Gly-Leu-Met-NH2, where X is a hydrophobic residue. The three major mammalian tachykinins are substance P (SP), neurokinin A (NKA), and neurokinin B (NKB). The physiological actions of tachykinins are mediated through three types of receptors: neurokinin receptor type 1 (NK1R), NK2R, and NK3R. SP is a high-affinity endogenous ligand for NK1R, which interacts with the Gq protein and activates phospholipase C, leading to elevation of intracellular calcium. NK2R is a high-affinity receptor for NKA, the tachykinin neuropeptide substance K. SP and NKA are found in the enteric nervous system and mediate in the regulation of gastrointestinal motility, secretion, vascular permeability, and pain perception. NK3R is activated by its high-affinity ligand, NKB, which is primarily involved in the central nervous system and plays a critical role in the regulation of gonadotropin hormone release and the onset of puberty.

KiSS1-derived peptide (kisspeptin) receptor, member of the class A family of seven-transmembrane G protein-coupled receptors; The G protein-coupled KiSS1-derived peptide receptor (GPR54 or kisspeptin receptor) binds the peptide hormone kisspeptin (previously known as metastin), which encoded by the metastasis suppressor gene (KISS1) expressed in various endocrine and reproductive tissues. The KiSS1 receptor is coupled to G proteins of the G(q/11) family, which lead to activation of phospholipase C and increase of intracellular calcium. This signaling cascade plays an important role in reproduction by regulating the secretion of gonadotropin-releasing hormone.

55-316 1.09e-05

prokineticin receptors, member of the class A family of seven-transmembrane G protein-coupled receptors; Prokineticins 1 (PROK1) and 2 (PROK2), also known as endocrine gland vascular endothelial factor and Bombina varigata 8, respectively, are multifunctional chemokine-like peptides that are highly conserved across species. Prokineticins can bind with similar affinities to two closely homologous 7-transmembrane G protein coupled receptors, PROKR1 and PROKR2, which are phylogenetically related to the tachykinin receptors. Prokineticins and their GPCRs are widely distributed in human tissues and are involved in numerous physiological roles, including gastrointestinal motility, generation of circadian rhythms, neuron migration and survival, pain sensation, angiogenesis, inflammation, and reproduction. Moreover, different point mutations in genes encoding PROK2 or its receptor (PROKR2) can lead to Kallmann syndrome, a disease characterized by delayed or absent puberty and impaired olfactory function.

41-175 1.48e-05

N-arachidonyl glycine receptor, GPR18, member of the class A family of seven-transmembrane G protein-coupled receptors; N-arachidonyl glycine (NAGly), an endogenous metabolite of the endocannabinoid anandamide, has been identified as an endogenous ligand of the G(i/o) protein-coupled receptor 18 (GPR18). NAGly is involved in directing microglial migration in the CNS through activation of GPR18. NAGly-GPR18 signaling is thought to play an important role in microglial-neuronal communication. Recent studies also show that GPR18 functions as the abnormal cannabidiol (Abn-CBD) receptor. Abn-CBD is a synthetic isomer of cannabidiol and is inactive at cannabinoid receptors (CB1 or CB2), but acts as a selective agonist at GPR18. The NAGly receptor is a member of the class A G protein-coupled receptor superfamily, which all have a common structural architecture comprising of seven-transmembrane (TM) alpha-helices interconnected by three extracellular and three intracellular loops. A general feature of GPCR signaling is agonist-induced conformational changes in the receptors, which then activate the heterotrimeric G proteins. G-proteins regulate a variety of cellular functions including metabolic enzymes, ion channels, and transporters, among many others.

protease-activated receptor 4, member of the class A family of seven-transmembrane G protein-coupled receptors; Protease-acted receptors (PARs) are seven-transmembrane proteins that belong to the class A G-protein coupled receptor (GPCR) family. Four different types of the protease-activated receptors have been identified: PAR1, PAR2, PAR3, and PAR4. PARs are predominantly expressed in platelets and are activated by serine proteases such as thrombin, trypsin, and tryptase. These proteases cleave the extracellular domain of the receptor to form a new N-terminus, which in turn functions as a tethered ligand. The newly-formed tethered ligand binds intramolecularly to activate the receptor and triggers G-protein binding and intracellular signaling. PAR1, PA3, and PAR4 are activated by thrombin, whereas PAR2 is activated by trypsin. The PARs are known to couple with several G-proteins including Gi (cAMP inhibitory), G12/13 (Rho and Ras activation), and Gq (calcium signaling) to activate downstream signaling messengers which induces numerous cellular and physiological effects.

G protein-coupled receptor 35, GPR55, and similar proteins, member of the class A family of seven-transmembrane G protein-coupled receptors; This subfamily is composed of GPR35, GPR55, and similar proteins. GPR35 shares closest homology with GPR55, and they belong to the class A G protein-coupled receptor superfamily, which all have a common structural architecture comprising of seven-transmembrane (TM) alpha-helices interconnected by three extracellular and three intracellular loops. A number of studies have suggested that GPR35 may play important physiological roles in hypertension, atherosclerosis, nociception, asthma, glucose homeostasis and diabetes, and inflammatory bowel disease. GPR35 is thought to be responsible for brachydactyly mental retardation syndrome, which is associated with a deletion comprising chromosome 2q37 in human, and is also implicated as a potential oncogene in stomach cancer. GPR35 couples to G(13) and G(i/o) proteins, whereas GPR55 has been reported to couple to G(13), G(12), or G(q) proteins. Activation of GPR55 leads to activation of phospholipase C, RhoA, ROCK, ERK, p38MAPK, and calcium release. Recently, lysophosphatidylinositol (LPI) has been identified as an endogenous ligand for GPR55, while several endogenous ligands for GPR35 have been identified including kynurenic acid, 2-oleoyl lysophosphatidic acid, and zaprinast.

45-308 3.96e-05

seven-transmembrane G protein-coupled receptor superfamily; This hierarchical evolutionary model represents the seven-transmembrane (7TM) receptors, often referred to as G protein-coupled receptors (GPCRs), which transmit physiological signals from the outside of the cell to the inside via G proteins. GPCRs constitute the largest known superfamily of transmembrane receptors across the three kingdoms of life that respond to a wide variety of extracellular stimuli including peptides, lipids, neurotransmitters, amino acids, hormones, and sensory stimuli such as light, smell and taste. All GPCRs share a common structural architecture comprising of seven-transmembrane (TM) alpha-helices interconnected by three extracellular and three intracellular loops. A general feature of GPCR signaling is agonist-induced conformational changes in the receptors, leading to activation of the heterotrimeric G proteins, which consist of the guanine nucleotide-binding G-alpha subunit and the dimeric G-beta-gamma subunits. The activated G proteins then bind to and activate numerous downstream effector proteins, which generate second messengers that mediate a broad range of cellular and physiological processes. However, some 7TM receptors, such as the type 1 microbial rhodopsins, do not activate G proteins. Based on sequence similarity, GPCRs can be divided into six major classes: class A (the rhodopsin-like family), class B (the Methuselah-like, adhesion and secretin-like receptor family), class C (the metabotropic glutamate receptor family), class D (the fungal mating pheromone receptors), class E (the cAMP receptor family), and class F (the frizzled/smoothened receptor family). Nearly 800 human GPCR genes have been identified and are involved essentially in all major physiological processes. Approximately 40% of clinically marketed drugs mediate their effects through modulation of GPCR function for the treatment of a variety of human diseases including bacterial infections.

47-307 4.05e-05

P2Y purinoceptor 10, member of the class A family of seven-transmembrane G protein-coupled receptors; P2Y10 receptor is a G-protein coupled receptor that is activated by both sphingosine-1-phosphate (S1P) and lysophosphatidic acid (LPA). Phylogenetic analysis of the class A GPCRs shows that P2Y10 is grouped into the cluster comprising nucleotide and lipid receptors. Although the mouse P2Y10 was found to be expressed in brain, lung, reproductive organs, and skeletal muscle, the physiological function of this receptor is not yet known. S1P and LPA are bioactive lipid molecules that induce a variety of cellular responses through G proteins: adhesion, invasion, cell migration and proliferation, among many others.

48-304 4.07e-05

hydroxycarboxylic acid receptors and related proteins, member of the class A family of seven-transmembrane G protein-coupled receptors; This group includes the hydroxycarboxylic acid receptors (HCARs) as well as their closely related receptors, GPR31 and oxoeicosanoid receptor 1 (OXER1). HCARs are members of the class A family of G-protein coupled receptors (GPCRs). HCAR subfamily contain three receptor subtypes: HCAR1, HCAR2, and HCAR3. The endogenous ligand of HCAR1 (also known as lactate receptor 1, GPR104, or GPR81) is L-lactic acid. The endogenous ligands of HCAR2 (also known as niacin receptor 1, GPR109A, nicotinic acid receptor) and HCAR3 (also known as niacin receptor 2, orGPR109B) are 3-hydroxybutyric acid and 3-hydroxyoctanoic acid, respectively. All three HCA receptors are expressed in adipocytes, and are coupled to G(i)-proteins mediating anti-lipolytic effects in fat cells. OXER1 is a receptor for eicosanoids and polyunsaturated fatty acids such as 5-oxo-6E,8Z,11Z,14Z-eicosatetraenoic acid (5-OXO-ETE), 5(S)-hydroperoxy-6E,8Z,11Z,14Z-eicosatetraenoic acid (5(S)-HPETE) and arachidonic acid, whereas GPR31 is a high-affinity receptor for 12-(S)-hydroxy-5,8,10,14-eicosatetraenoic acid (12-S-HETE).

44-310 4.11e-05

growth hormone secretagogue receptor, member of the class A family of seven-transmembrane G protein-coupled receptors; Growth hormone secretagogue receptor, GHSR, is also known as GH-releasing peptide receptor (GHRP) or Ghrelin receptor. Ghrelin, the endogenous ligand for GHSR, is an acylated 28-amino acid peptide hormone produced by ghrelin cells in the gastrointestinal tract. Ghrelin, also called hunger hormone, is involved in the regulation of growth hormone release, appetite and feeding, gut motility, lipid and glucose metabolism, and energy balance. It also plays a role in the cardiovascular, immune, and reproductive systems. GHSR couples to G-alpha-11 proteins. Both ghrelin and GHSR are expressed in a wide range of cancer tissues. Recent studies suggested that ghrelin may play a role in processes associated with cancer progression, including cell proliferation, metastasis, apoptosis, and angiogenesis.

47-304 5.42e-05

proton-sensing G protein-coupled receptor 65, member of the class A family of seven-transmembrane G protein-coupled receptors; The T cell death associated gene-8 receptor (TDAG8, also known as GPR65) is a member of the proton-sensing G-protein-coupled receptor (GPCR) family which also includes the G2 accumulation receptor (G2A, also known as GPR132), ovarian cancer G-protein receptor 1 (OGR-1, GPR68), and G-protein-coupled receptor 4 (GPR4). Proton-sensing G-protein coupled receptors sense pH of 7.6 to 6.0 and mediates a variety of biological activities in neutral and mildly acidic pH conditions, whereas the acid-sensing ionotropic ion channels typically sense strong acidic pH. Activation of TDAG8 by extracellular acidosis increases the cAMP production, stimulates Rho, and induces stress fiber formation. TDAG8 has also been shown to regulate the extracellular acidosis-induced inhibition of pro-inflammatory cytokine production in peritoneal macrophages.

P2Y purinoceptor 4, member of the class A family of seven-transmembrane G protein-coupled receptors; P2Y4 belongs to the P2Y receptor family of purinergic G-protein coupled receptors. This family is composed of eight subtypes, which are activated by naturally occurring extracellular nucleotides such as ATP, ADP, UTP, UDP, and UDP-glucose. These eight receptors are ubiquitous in human tissues and can be further classified into two subfamilies based on sequence homology and second messenger coupling: a subfamily of five P2Y1-like receptors (P2Y1, P2Y2, P2Y4, P2Y6, and P2Y11Rs) that are coupled to G(q) protein to activate phospholipase C (PLC) and a second subfamily of three P2Y12-like receptors (P2Y12, P2YR13, and P2Y14Rs) that are coupled to G(i) protein to inhibit adenylate cyclase. Several cloned subtypes, such as P2Y3, P2Y5, and P2Y7-10, are not functional mammalian nucleotide receptors. The native agonists for P2Y receptors are: ATP (P2Y2, P2Y12), ADP (P2Y1, P2Y12, and P2Y13), UTP (P2Y2, P2Y4), UDP (P2Y6, P2Y14), and UDP-glucose (P2Y14).

47-304 9.31e-05

protease-activated receptor 2, member of the class A family of seven-transmembrane G protein-coupled receptors; Protease-acted receptors (PARs) are seven-transmembrane proteins that belong to the class A G-protein coupled receptor (GPCR) family. Four different types of the protease-activated receptors have been identified: PAR1, PAR2, PAR3, and PAR4. PARs are predominantly expressed in platelets and are activated by serine proteases such as thrombin, trypsin, and tryptase. These proteases cleave the extracellular domain of the receptor to form a new N-terminus, which in turn functions as a tethered ligand. The newly-formed tethered ligand binds intramolecularly to activate the receptor and triggers G-protein binding and intracellular signaling. PAR1, PA3, and PAR4 are activated by thrombin, whereas PAR2 is activated by trypsin. The PARs are known to couple with several G-proteins including Gi (cAMP inhibitory), G12/13 (Rho and Ras activation), and Gq (calcium signaling) to activate downstream signaling messengers which induces numerous cellular and physiological effects.

41-312 9.48e-05

neuropeptide S receptor, member of the class A family of seven-transmembrane G protein-coupled receptors; Neuropeptide S (NPS) promotes arousal and anxiolytic-like effects by activating its cognate receptor NPSR. NPSR is widely expressed in the brain, and its activation induces an elevation of intracellular calcium and cAMP concentrations, presumably by coupling to G(s) and G(q) proteins. Mutations in NPSR have been associated with an increased susceptibility to asthma. NPSR was originally identified as an orphan receptor GPR154 and is also known as G protein receptor for asthma susceptibility (GPRA) or vasopressin receptor-related receptor 1 (VRR1).

neuromedin B receptor, member of the class A family of seven-transmembrane G protein-coupled receptors; The neuromedin B receptor (NMBR), also known as BB1, is a G-protein coupled receptor whose endogenous ligand is the neuropeptide neuromedin B. Neuromedin B is a potent mitogen and growth factor for normal and cancerous lung and for gastrointestinal epithelial tissues. NMBR is widely distributed in the CNS, with especially high levels in olfactory nucleus and thalamic regions. The receptor couples primarily to a pertussis-toxin-insensitive G protein of the Gq/11 family, which leads to the activation of phospholipase C. NMBR belongs to the bombesin subfamily of G-protein coupled receptors, whose members also include gastrin-releasing peptide receptor (GRPR) and bombesin receptor subtype 3 (BRS-3). Bombesin is a tetradecapeptide, originally isolated from frog skin.

motilin receptor, member of the class A family of seven-transmembrane G protein-coupled receptors; Motilin receptor, also known as GPR38, is a G-protein coupled receptor that binds the endogenous ligand motilin. Motilin is a 22 amino acid peptide hormone expressed throughout the gastrointestinal tract and stimulates contraction of gut smooth muscle. Motilin is also called as the housekeeper of the gut because it is responsible for the proper filling and emptying of the gastrointestinal tract in response to food intake, and for stimulating the production of pepsin. Motilin receptor shares significant amino acid sequence identity with the growth hormone secretagogue receptor (GHSR) and neurotensin receptors (NTS-R1 and 2).

48-306 1.47e-04

G protein-coupled receptor 31, member of the class A family of seven-transmembrane G protein-coupled receptors; GPR31, also known as 12-(S)-HETE receptor, is a high-affinity receptor for 12-(S)-hydroxy-5,8,10,14-eicosatetraenoic acid. Phylogenetic analysis showed that GPR31 and oxoeicosanoid receptor 1 (OXER1, GPR170) are the most closely related receptors to the hydroxycarboxylic acid receptor family (HCARs). GPR31, like OXER1, activates the ERK1/2 (MAPK3/MAPK1) pathway of intracellular signaling, but unlike the OXER1, does not cause increase in the cytosolic calcium level. GPR31 is also shown to activate NFkB. 12-(S)-HETE is a 12-lipoxygenase metabolite of arachidonic acid produced by mammalian platelets and tumor cells. It promotes tumor cells adhesion to endothelial cells and sub-endothelial matrix, which is a critical step for metastasis.

46-310 1.71e-04

P2Y purinoceptors 6 and 3, and similar proteins, member of the class A family of seven-transmembrane G protein-coupled receptors; This group includes P2Y receptor 6 (P2Y6), P2Y3, and P2Y3-like proteins. These receptors belong to the G(i) class of a family of purinergic G-protein coupled receptors. In the CNS, P2Y6 plays a role in microglia activation and phagocytosis, and is involved in the secretion of interleukin from monocytes and macrophages in the immune system. The P2Y receptor family is composed of eight subtypes, which are activated by naturally occurring extracellular nucleotides such as ATP, ADP, UTP, UDP, and UDP-glucose. These eight receptors are ubiquitous in human tissues and can be further classified into two subfamilies based on sequence homology and second messenger coupling: a subfamily of five P2Y1-like receptors (P2Y1, P2Y2, P2Y4, P2Y6, and P2Y11Rs) that are coupled to G(q) protein to activate phospholipase C (PLC) and a second subfamily of three P2Y12-like receptors (P2Y12, P2YR13, and P2Y14Rs) that are coupled to G(i) protein to inhibit adenylate cyclase. Several cloned subtypes, such as P2Y3, P2Y5, and P2Y7-10, are not functional mammalian nucleotide receptors. The native agonists for P2Y receptors are: ATP (P2Y2, P2Y12), ADP (P2Y1, P2Y12, and P2Y13), UTP (P2Y2, P2Y4), UDP (P2Y6, P2Y14), and UDP-glucose (P2Y14).

50-307 1.81e-04

melanin concentrating hormone receptor 1, member of the class A family of seven-transmembrane G protein-coupled receptors; Melanin-concentrating hormone receptor (MCHR) binds melanin concentrating hormone and is presumably involved in the neuronal regulation of food intake and energy homeostasis. Despite strong homology with somatostatin receptors, MCHR does not appear to bind somatostatin. Two MCHRs have been characterized in vertebrates, MCHR1 and MCHR2. MCHR1 is expressed in all mammals, whereas MCHR2 is only expressed in the higher order mammals, such as humans, primates, and dogs, and is not found in rodents. All GPCRs have a common structural architecture comprising of seven-transmembrane (TM) alpha-helices interconnected by three extracellular and three intracellular loops. A general feature of GPCR signaling is agonist-induced conformational changes in the receptors, leading to activation of the heterotrimeric G proteins, which consist of the guanine nucleotide-binding G-alpha subunit and the dimeric G-beta-gamma subunits. The activated G proteins then bind to and activate numerous downstream effector proteins, which generate second messengers that mediate a broad range of cellular and physiological processes.

47-311 2.04e-04

proton-sensing G protein-coupled receptor 4, member of the class A family of seven-transmembrane G protein-coupled receptors; G-protein-coupled receptor 4 (GPR4) is a member of the proton-sensing G-protein-coupled receptor (GPCR) family which also includes the G2 accumulation receptor (G2A, also known as GPR132), the T cell death associated gene-8 receptor (TDAG8, GPR65), ovarian cancer G-protein receptor 1 (OGR-1, GPR68), and G-protein-coupled receptor 4 (GPR4). Proton-sensing G-protein coupled receptors sense pH of 7.6 to 6.0 and mediates a variety of biological activities in neutral and mildly acidic pH conditions, whereas the acid-sensing ionotropic ion channels typically sense strong acidic pH. GPR4 overexpression in melanoma cells was shown to reduce cell migration, membrane ruffling, and cell spreading under acidic pH conditions. Activation of GPR4 via extracellular acidosis is coupled to the G(s), G(q), and G(12/13) pathways.

protease-activated receptor 3, member of the class A family of seven-transmembrane G protein-coupled receptors; Protease-acted receptors (PARs) are seven-transmembrane proteins that belong to the class A G-protein coupled receptor (GPCR) family. Four different types of the protease-activated receptors have been identified: PAR1, PAR2, PAR3, and PAR4. PARs are predominantly expressed in platelets and are activated by serine proteases such as thrombin, trypsin, and tryptase. These proteases cleave the extracellular domain of the receptor to form a new N-terminus, which in turn functions as a tethered ligand. The newly-formed tethered ligand binds intramolecularly to activate the receptor and triggers G-protein binding and intracellular signaling. PAR1, PA3, and PAR4 are activated by thrombin, whereas PAR2 is activated by trypsin. The PARs are known to couple with several G-proteins including Gi (cAMP inhibitory), G12/13 (Rho and Ras activation), and Gq (calcium signaling) to activate downstream signaling messengers which induces numerous cellular and physiological effects.

endothelin receptors, member of the class A family of seven-transmembrane G protein-coupled receptors; Endothelins are 21-amino acid peptides which able to activate a number of signal transduction processes including phospholipase A2, phospholipase C, and phospholipase D, as well as cytosolic protein kinase activation. They play an important role in the regulation of the cardiovascular system and are the most potent vasoconstrictors identified, stimulating cardiac contraction, regulating the release of vasoactive substances, and stimulating mitogenesis in blood vessels. Two endothelin receptor subtypes have been isolated and identified in vertebrates, endothelin A receptor (ET-A) and endothelin B receptor (ET-B), and are members of the seven transmembrane class A G-protein coupled receptor family which activate multiple effectors via different types of G protein. Some vertebrates contain a third subtype, endothelin A receptor (ET-C). ET-A receptors are mainly located on vascular smooth muscle cells, whereas ET-B receptors are present on endothelial cells lining the vessel wall. Endothelin receptors have also been found in the brain.

46-306 3.79e-04

proton-sensing G protein-coupled receptor 132, member of the class A family of seven-transmembrane G protein-coupled receptors; The G2 accumulation receptor (G2A, also known as GPR132) is a member of the proton-sensing G-protein-coupled receptor (GPCR) family which also includes the T cell death associated gene-8 (TDAG8, GPR65) receptor, ovarian cancer G-protein receptor 1 (OGR-1, GPR68), and G-protein-coupled receptor 4 (GPR4). Proton-sensing G-protein coupled receptors sense pH of 7.6 to 6.0 and mediates a variety of biological activities in neutral and mildly acidic pH conditions, whereas the acid-sensing ionotropic ion channels typically sense strong acidic pH. G2A was originally identified as a stress-inducible receptor that causes the cell cycle arrest at G2/M phase when serum is deprived. Lysophosphatidylcholine was identified as a ligand for G2A, and whose overexpression was shown to induce cell proliferation, oncogenic transformation, and apoptosis.

55-258 4.31e-04

histamine receptor subtypes H3R and H4R, member of the class A family of seven-transmembrane G protein-coupled receptors; This group includes histamine subtypes H3R and H4R, members of the histamine receptor family, which belong to the class A of GPCRs. Histamine plays a key role as chemical mediator and neurotransmitter in various physiological and pathophysiological processes in the central and peripheral nervous system. Histamine exerts its functions by binding to four different G protein-coupled receptors (H1-H4). The H3 and H4 receptors couple to the G(i)-proteins, which leading to the inhibition of cAMP formation. The H3R receptor functions as a presynaptic autoreceptors controlling histamine release and synthesis. The H4R plays an important role in histamine-mediated chemotaxis in mast cells and eosinophils. All GPCRs have a common structural architecture comprising of seven-transmembrane (TM) alpha-helices interconnected by three extracellular and three intracellular loops. A general feature of GPCR signaling is agonist-induced conformational changes in the receptors, leading to activation of the heterotrimeric G proteins, which consist of the guanine nucleotide-binding G-alpha subunit and the dimeric G-beta-gamma subunits. The activated G proteins then bind to and activate numerous downstream effector proteins, which generate second messengers that mediate a broad range of cellular and physiological processes.

putative G protein-coupled receptor 34, member of the class A family of seven-transmembrane G protein-coupled receptors; This subgroup represents the G-protein coupled receptor 34 of unknown function. Orphan GPR34 is a member of the rhodopsin-like, class A GPCRs, which is a widespread protein family that includes the light-sensitive rhodopsin as well as receptors for biogenic amines, lipids, nucleotides, odorants, peptide hormones, and a variety of other ligands. All GPCRs have a common structural architecture comprising of seven-transmembrane (TM) alpha-helices interconnected by three extracellular and three intracellular loops. A general feature of GPCR signaling is agonist-induced conformational changes in the receptors, leading to activation of the heterotrimeric G proteins, which consist of the guanine nucleotide-binding G-alpha subunit and the dimeric G-beta-gamma subunits. The activated G proteins then bind to and activate numerous downstream effector proteins, which generate second messengers that mediate a broad range of cellular and physiological processes.

47-304 6.02e-04

insect photoreceptors R1-R6 and similar proteins, member of the class A family of seven-transmembrane G protein-coupled receptors; This group includes the insect photoreceptors and their closely related proteins. The Drosophila eye is composed of about 800 unit eyes called ommatidia, each of which contains eight photoreceptor cells (R1-R8). The six outer photoreceptors (R1-R6) function like the vertebrate rods and are responsible for motion detection in dim light and image formation. The R1-R6 photoreceptors express a blue-absorbing pigment, Rhodopsin 1(Rh1). The inner photoreceptors (R7 and R8) are considered the equivalent of the color-sensitive vertebrate cone cells, which express a range of different pigments. The R7 photoreceptors express one of two different UV absorbing pigments, either Rh3 or Rh4. Likewise, the R8 photoreceptors express either the blue absorbing pigment Rh5 or green absorbing pigment Rh6. These photoreceptors belong the class A of the G protein-coupled receptors and possess seven-transmembrane (TM) alpha-helices interconnected by three extracellular and three intracellular loops.

46-316 6.35e-04

neuropeptide Y receptor type 1, member of the class A family of seven-transmembrane G protein-coupled receptors; NPY is a 36-amino acid peptide neurotransmitter with a C-terminal tyrosine amide residue that is widely distributed in the brain and the autonomic nervous system of many mammalian species. NPY exerts its functions through five, G-protein coupled receptor subtypes including NPY1R, NPY2R, NPY4R, NPY5R, and NPY6R; however, NPY6R is not functional in humans. NYP receptors are also activated by its two other family members, peptide YY (PYY) and pancreatic polypeptide (PP). They typically couple to G(i) or G(o) proteins, which leads to a decrease in adenylate cyclase activity, thereby decreasing intracellular cAMP levels, and are involved in diverse physiological roles including appetite regulation, circadian rhythm, and anxiety. When NPY signals through NPY2R in concert with NPY5R, it induces angiogenesis and consequently plays an important role in revascularization and wound healing. On the other hand, when NPY acts through NPY1R and NPYR5, it acts as a vascular mitogen, leading to restenosis and atherosclerosis.

47-310 6.72e-04

neuromedin U receptor subtype 2, member of the class A family of seven-transmembrane G protein-coupled receptors; Neuromedin U (NMU) is a highly conserved neuropeptide with a common C-terminal heptapeptide sequence (FLFRPRN-amide) found at the highest levels in the gastrointestinal tract and pituitary gland of mammals. Disruption or replacement of residues in the conserved heptapeptide region can result in the reduced ability of NMU to stimulate smooth-muscle contraction. Two G-protein coupled receptor subtypes, NMU-R1 and NMU-R2, with a distinct expression pattern, have been identified to bind NMU. NMU-R1 is expressed primarily in the peripheral nervous system, while NMU-R2 is mainly found in the central nervous system. Neuromedin S, a 36 amino-acid neuropeptide that shares a conserved C-terminal heptapeptide sequence with NMU, is a highly potent and selective NMU-R2 agonist. Pharmacological studies have shown that both NMU and NMS inhibit food intake and reduce body weight, and that NMU increases energy expenditure.

P2Y purinoceptor 1, member of the class A family of seven-transmembrane G protein-coupled receptors; P2Y1 belongs to the P2Y receptor family of purinergic G-protein coupled receptors. This family is composed of eight subtypes, which are activated by naturally occurring extracellular nucleotides such as ATP, ADP, UTP, UDP, and UDP-glucose. These eight receptors are ubiquitous in human tissues and can be further classified into two subfamilies based on sequence homology and second messenger coupling: a subfamily of five P2Y1-like receptors (P2Y1, P2Y2, P2Y4, P2Y6, and P2Y11Rs) that are coupled to G(q) protein to activate phospholipase C (PLC) and a second subfamily of three P2Y12-like receptors (P2Y12, P2YR13, and P2Y14Rs) that are coupled to G(i) protein to inhibit adenylate cyclase. Several cloned subtypes, such as P2Y3, P2Y5, and P2Y7-10, are not functional mammalian nucleotide receptors. The native agonists for P2Y receptors are: ATP (P2Y2, P2Y12), ADP (P2Y1, P2Y12, and P2Y13), UTP (P2Y2, P2Y4), UDP (P2Y6, P2Y14), and UDP-glucose (P2Y14).

G protein-coupled receptor 68, member of the class A family of seven-transmembrane G protein-coupled receptors; The ovarian cancer G-protein receptor 1 (OGR1, also known as GPR68) is a member of the proton-sensing G-protein-coupled receptor (GPCR) family which also includes the G2 accumulation receptor (G2A, also known as GPR132), the T cell death associated gene-8 receptor (TDAG8, GPR65), and the G-protein-coupled receptor 4 (GPR4). Proton-sensing G-protein coupled receptors sense pH of 7.6 to 6.0 and mediates a variety of biological activities in neutral and mildly acidic pH conditions, whereas the acid-sensing ionotropic ion channels typically sense strong acidic pH. Knock-out mice studies have suggested that OGR1 plays a role in the regulation of insulin secretion and glucose metabolism. OGR1 couples to G(q/11) proteins and activates phospholipase C and Ca2+ signaling pathways.

45-310 8.65e-04

vasopressin and oxytocin receptors, member of the class A family of seven-transmembrane G protein-coupled receptors; Vasopressin (also known as arginine vasopressin or anti-diuretic hormone) and oxytocin are synthesized in the hypothalamus and are released from the posterior pituitary gland. The actions of vasopressin are mediated by the interaction of this hormone with three receptor subtypes: V1aR, V1bR, and V2R. These subtypes are differ in localization, function, and signaling pathways. Activation of V1aR and V1bR stimulate phospholipase C, while activation of V2R stimulates adenylate cyclase. Although vasopressin and oxytocin differ only by two amino acids and stimulate the same cAMP/PKA pathway, they have divergent physiological functions. Vasopressin is involved in regulating blood pressure and the balance of water and sodium ions, whereas oxytocin plays an important role in the uterus during childbirth and in lactation.

47-306 1.03e-03

gastrin-releasing peptide receptor, member of the class A family of seven-transmembrane G protein-coupled receptors; The gastrin-releasing peptide receptor (GRPR) is a G-protein coupled receptor whose endogenous ligand is gastrin releasing peptide. GRP shares high sequence homology with the neuropeptide neuromedin B in the C-terminal region. This receptor is high glycosylated and couples to a pertussis-toxin-insensitive G protein of the family of Gq/11, which leads to the activation of phospholipase C. Gastrin-releasing peptide (GRP) is a potent mitogen for neoplastic tissues and involved in regulating multiple functions of the gastrointestinal and central nervous systems. These include the release of gastrointestinal hormones, the contraction of smooth muscle cells, and the proliferation of epithelial cells. GRPR belongs to the bombesin subfamily of G-protein coupled receptors, whose members also include neuromedin B receptor (NMBR) and bombesin receptor subtype 3 (BRS-3). Bombesin is a tetradecapeptide, originally isolated from frog skin.

cholecystokinin receptors, member of the class A family of seven-transmembrane G protein-coupled receptors; Cholecystokinin receptors (CCK-AR and CCK-BR) are a group of G-protein coupled receptors which bind the peptide hormones cholecystokinin (CCK) or gastrin. CCK, which facilitates digestion in the small intestine, and gastrin, a major regulator of gastric acid secretion, are highly similar peptides. Like gastrin, CCK is a naturally-occurring linear peptide that is synthesized as a preprohormone, then proteolytically cleaved to form a family of peptides with the common C-terminal sequence (Gly-Trp-Met-Asp-Phe-NH2), which is required for full biological activity. CCK-AR (type A, alimentary; also known as CCK1R) is found abundantly on pancreatic acinar cells and binds only sulfated CCK-peptides with very high affinity, whereas CCK-BR (type B, brain; also known as CCK2R), the predominant form in the brain and stomach, binds CCK or gastrin and discriminates poorly between sulfated and non-sulfated peptides. CCK is implicated in regulation of digestion, appetite control, and body weight, and is involved in neurogenesis via CCK-AR. There is some evidence to support that CCK and gastrin, via their receptors, are involved in promoting cancer development and progression, acting as growth and invasion factors.

49-309 1.73e-03

melatonin receptor subtype 1B, member of the class A family of seven-transmembrane G protein-coupled receptors; Melatonin (N-acetyl-5-methoxytryptamine) is a naturally occurring sleep-promoting chemical found in vertebrates, invertebrates, bacteria, fungi, and plants. In mammals, melatonin is secreted by the pineal gland and is involved in regulation of circadian rhythms. Its production peaks during the nighttime, and is suppressed by light. Melatonin is shown to be synthesized in other organs and cells of many vertebrates, including the Harderian gland, leukocytes, skin, and the gastrointestinal (GI) tract, which contains several hundred times more melatonin than the pineal gland and is involved in the regulation of GI motility, inflammation, and sensation. Melatonin exerts its pleiotropic physiological effects through specific membrane receptors, named MT1A, MT1B, and MT1C, which belong to the class A rhodopsin-like G-protein coupled receptor family. MT1A and MT1B subtypes are present in mammals, whereas MT1C subtype has been found in amphibians and birds. The melatonin receptors couple to G proteins of the G(i/o) class, leading to the inhibition of adenylate cyclase.

45-120 1.88e-03

free fatty acid receptors, member of the class A family of seven-transmembrane G protein-coupled receptors; This subfamily includes the free fatty acid receptors (FFARs) which bind free fatty acids (FFAs). They belong to the class A G-protein coupled receptors and are composed of three members, each encoded by a separate gene (FFAR1, FFAR2, and FFAR3). These genes and a fourth pseudogene, GPR42, are localized together on chromosome 19. FFAR1 is a receptor for medium- and long-chain FFAs, whereas FFAR2 and FFAR3 are receptors for short chain FFAs (SCFAs), which have different ligand affinities. FFAR1 directly mediates FFA stimulation of glucose-stimulated insulin secretion and also indirectly increases insulin secretion by enhancing the release of incretin. FFAR2 activation by SCFA suppresses adipose insulin signaling, which leads to the inhibition of fat accumulation in adipose tissue. FAAR3 is expressed in intestinal L cells, which produces glucagon-like peptide 1 (GLP-1) and peptide YY (PYY), suggesting that this receptor may be involved in energy homeostasis. FFARs are considered important components of the body's nutrient sensing mechanism, and therefore, these receptors are potential therapeutic targets for the treatment of metabolic disorders, such as type 2 diabetes and obesity.

leukotriene B4 receptor subtype 1 (LTB4R1 or BLT1), member of the class A family of seven-transmembrane G protein-coupled receptors; Leukotriene B4 (LTB4), a metabolite of arachidonic acid, is a powerful chemotactic activator for granulocytes and macrophages. Two receptors for LTB4 have been identified: a high-affinity receptor (LTB4R1 or BLT1) and a low-affinity receptor (TB4R2 or BLT2). Both BLT1 and BLT2 receptors belong to the rhodopsin-like G-protein coupled receptor superfamily and primarily couple to G(i) proteins, which lead to chemotaxis, calcium mobilization, and inhibition of adenylate cyclase. In some cells, they can also couple to the Gq-like protein, G16, and activate phospholipase C. LTB4 is involved in mediating inflammatory processes, immune responses, and host defense against infection. Studies have shown that LTB4 stimulates leukocyte extravasation, neutrophil degranulation, lysozyme release, and reactive oxygen species generation.

endothelin C receptor, member of the class A family of seven-transmembrane G protein-coupled receptors; Endothelins are able to activate a number of signal transduction processes including phospholipase A2, phospholipase C, and phospholipase D, as well as cytosolic protein kinase activation. They play an important role in the regulation of the cardiovascular system and are the most potent vasoconstrictors identified, stimulating cardiac contraction, regulating the release of vasoactive substances, and stimulating mitogenesis in blood vessels. Two endothelin receptor subtypes have been isolated and identified in vertebrates, endothelin A receptor (ET-A) and endothelin B receptor (ET-B), and are members of the seven transmembrane class A G-protein coupled receptor family which activate multiple effectors via different types of G protein. Some vertebrates contain a third subtype, endothelin A receptor (ET-C). ET-A receptors are mainly located on vascular smooth muscle cells, whereas ET-B receptors are present on endothelial cells lining the vessel wall. Endothelin receptors have also been found in the brain. The ET-C receptor is specific for endothelin-3 on frog dermal melanophores; its activation causes dispersion of pigment granules.

144-317 3.00e-03

serotonin receptor subtype 2C, member of the class A family of seven-transmembrane G protein-coupled receptors; The 5-HT2 receptors are a subfamily of serotonin receptors that bind the neurotransmitter serotonin (5HT; 5-hydroxytryptamine) in the central nervous system (CNS). The 5-HT2 subfamily is composed of three subtypes that mediate excitatory neurotransmission: 5-HT2A, 5-HT2B, and 5-HT2C. They are selectively linked to G proteins of the G(q/11) family and activate phospholipase C, which leads to activation of protein kinase C and calcium release. In the CNS, serotonin is involved in the regulation of appetite, mood, sleep, cognition, learning and memory, as well as implicated in diseases such as migraine, schizophrenia, and depression. Indeed, 5-HT2 receptors are attractive targets for a variety of psychoactive drugs, ranging from atypical antipsychotic drugs, antidepressants, and anxiolytics, which have an antagonistic action on 5-HT2 receptors, to hallucinogens, which act as agonists at postsynaptic 5-HT2 receptors. All GPCRs have a common structural architecture comprising of seven-transmembrane (TM) alpha-helices interconnected by three extracellular and three intracellular loops. A general feature of GPCR signaling is agonist-induced conformational changes in the receptors, leading to activation of the heterotrimeric G proteins, which consist of the guanine nucleotide-binding G-alpha subunit and the dimeric G-beta-gamma subunits. The activated G proteins then bind to and activate numerous downstream effector proteins, which generate second messengers that mediate a broad range of cellular and physiological processes.

47-306 3.10e-03

P2Y purinoceptor 2, member of the class A family of seven-transmembrane G protein-coupled receptors; P2Y2 belongs to the P2Y receptor family of purinergic G-protein coupled receptors and is implicated to play a role in the control of the cell cycle of endometrial carcinoma cells. The P2Y receptor family is composed of eight subtypes, which are activated by naturally occurring extracellular nucleotides such as ATP, ADP, UTP, UDP, and UDP-glucose. These eight receptors are ubiquitous in human tissues and can be further classified into two subfamilies based on sequence homology and second messenger coupling: a subfamily of five P2Y1-like receptors (P2Y1, P2Y2, P2Y4, P2Y6, and P2Y11Rs) that are coupled to G(q) protein to activate phospholipase C (PLC) and a second subfamily of three P2Y12-like receptors (P2Y12, P2YR13, and P2Y14Rs) that are coupled to G(i) protein to inhibit adenylate cyclase. Several cloned subtypes, such as P2Y3, P2Y5, and P2Y7-10, are not functional mammalian nucleotide receptors. The native agonists for P2Y receptors are: ATP (P2Y2, P2Y12), ADP (P2Y1, P2Y12, and P2Y13), UTP (P2Y2, P2Y4), UDP (P2Y6, P2Y14), and UDP-glucose (P2Y14).

mas-related G protein-coupled receptors, member of the class A family of seven-transmembrane G protein-coupled receptors; The Mas-related G-protein coupled receptor (Mrgpr) family constitutes a group of orphan receptors exclusively expressed in nociceptive primary sensory neurons and mast cells in the skin. Members of the Mrgpr family have been implicated in the modulation of nociception, pruritus (itching), and mast cell degranulation. The Mrgpr family in rodents and humans contains more than 50 members that can be grouped into 9 distinct subfamilies: MrgprA, B, C (MrgprX1), D, E, F, G, H (GPR90), and the primate-specific MrgprX subfamily. Some Mrgprs can be activated by endogenous ligands such as beta-alanine, adenine (a cell metabolite and potential transmitter), RF-amide related peptides, or salusin-beta (a bioactive peptide). However, the effects of these agonists are not clearly understood, and the physiological role of the individual receptor family members remains to be determined. Also included in this family is Mas-related G-protein coupled receptor 1-like (MAS1L) which is only found in primates. The angiotensin-II metabolite angiotensin is an endogenous ligand for MAS1L.

histamine receptor subtype H4R, member of the class A family of seven-transmembrane G protein-coupled receptors; This group includes histamine subtype H4R, a member of the histamine receptor family, which belong to the class A of GPCRs. Histamine plays a key role as chemical mediator and neurotransmitter in various physiological and pathophysiological processes in the central and peripheral nervous system. Histamine exerts its functions by binding to four different G protein-coupled receptors (H1-H4). The H3 and H4 receptors couple to the G(i)-proteins, which leading to the inhibition of cAMP formation. The H3R receptor functions as a presynaptic autoreceptors controlling histamine release and synthesis. The H4R plays an important role in histamine-mediated chemotaxis in mast cells and eosinophils. All GPCRs have a common structural architecture comprising of seven-transmembrane (TM) alpha-helices interconnected by three extracellular and three intracellular loops. A general feature of GPCR signaling is agonist-induced conformational changes in the receptors, leading to activation of the heterotrimeric G proteins, which consist of the guanine nucleotide-binding G-alpha subunit and the dimeric G-beta-gamma subunits.

209-309 4.62e-03

adenosine receptor subtype 2AB, member of the class A family of seven-transmembrane G protein-coupled receptors; The A2B receptor, a member of the adenosine receptor family of G protein-coupled receptors, binds adenosine as its endogenous ligand and is involved in regulating myocardial oxygen consumption and coronary blood flow. High-affinity A2A and low-affinity A2B receptors are preferentially coupled to G proteins of the stimulatory (Gs) family, which lead to activation of adenylate cyclase and thereby increasing the intracellular cAMP levels. The A2A receptor activation protects against tissue injury and acts as anti-inflammatory agent. In human skin endothelial cells, activation of A2B receptor, but not the A2A receptor, promotes angiogenesis. Alternatively, activated A2A receptor, but not the A2B receptor, promotes angiogenesis in human umbilical vein and lung microvascular endothelial cells. The A2A receptor alters cardiac contractility indirectly by modulating the anti-adrenergic effect of A1 receptor, while the A2B receptor exerts direct effects on cardiac contractile function, but does not modulate beta-adrenergic or A1 anti-adrenergic effects.

46-316 4.81e-03

prolactin-releasing peptide receptor, member of the class A family of seven-transmembrane G protein-coupled receptors; Prolactin-releasing peptide (PrRP) receptor (previously known as GPR10) is expressed in the central nervous system with the highest levels located in the anterior pituitary and is activated by its endogenous ligand PrRP, a neuropeptide possessing a C-terminal Arg-Phe-amide motif. There are two active isoforms of PrRP in mammals: one consists of 20 amino acids (PrRP-20) and the other consists of 31 amino acids (PrRP-31), where PrRP-20 is a C-terminal fragment of PrRP-31. Binding of PrRP to the receptor coupled to G(i/o) proteins activates the extracellular signal-related kinase (ERK) and it can also couple to G(q) protein leading to an increase in intracellular calcium and activation of c-Jun N-terminal protein kinase (JNK). The PrRP receptor shares significant sequence homology with the neuropeptide Y (NPY) receptor, and micromolar levels of NPY can bind and completely inhibit the PrRP-evoked intracellular calcium response in PrRP receptor-expressing cells, suggesting that the PrRP receptor shares a common ancestor with the NPY receptors. PrRP has been shown to reduce food intake and body weight and modify body temperature when administered in rats. It also has been shown to decrease circulating growth hormone levels by activating somatostatin-secreting neurons in the hypothalamic periventricular nucleus.

growth hormone secretagogue receptor, motilin receptor, and related proteins, member of the class A family of seven-transmembrane G protein-coupled receptors; This subfamily includes growth hormone secretagogue receptor (GHSR or ghrelin receptor), motilin receptor (also called GPR38), and related proteins. Both GHSR and GPR38 bind peptide hormones. Ghrelin, the endogenous ligand for GHSR, is an acylated 28-amino acid peptide hormone produced by ghrelin cells in the gastrointestinal tract. Ghrelin is also called the hunger hormone and is involved in the regulation of growth hormone release, appetite and feeding, gut motility, lipid and glucose metabolism, and energy balance. Motilin, the ligand for GPR38, is a 22 amino acid peptide hormone expressed throughout the gastrointestinal tract and stimulates contraction of gut smooth muscle. It is involved in the regulation of digestive tract motility.

46-304 6.14e-03

alpha-1 adrenergic receptors subtype B, member of the class A family of seven-transmembrane G protein-coupled receptors; The alpha-1 adrenergic receptors (or adrenoceptors) are a subfamily of the class A rhodopsin-like GPCRs that share a common architecture of seven transmembrane helices. This subfamily consists of three highly homologous receptor subtypes that primarily mediate smooth muscle contraction: alpha-1A, alpha-1B, and alpha-1D. Activation of alpha-1 receptors by catecholamines such as norepinephrine and epinephrine couples to the G(q) protein, which then activates the phospholipase C pathway, leading to an increase in IP3 and calcium. Consequently, the elevation of intracellular calcium concentration leads to vasoconstriction in smooth muscle of blood vessels. In addition, activation of alpha-1 receptors by phenylpropanolamine (PPA) produces anorexia and may induce appetite suppression in rats.

putative neuropeptide receptor BNGR-A34 and similar proteins, member of the class A family of seven-transmembrane G protein-coupled receptors; This subgroup includes putative neuropeptide receptor BNGR-A34 found in silkworm and its closely related proteins from invertebrates. They are members of the class A rhodopsin-like GPCRs, which represent a widespread protein family that includes the light-sensitive rhodopsin as well as receptors for biogenic amines, lipids, nucleotides, odorants, peptide hormones, and a variety of other ligands. All GPCRs have a common structural architecture comprising of seven-transmembrane (TM) alpha-helices interconnected by three extracellular and three intracellular loops. A general feature of GPCR signaling is agonist-induced conformational changes in the receptors, leading to activation of the heterotrimeric G proteins, which consist of the guanine nucleotide-binding G-alpha subunit and the dimeric G-beta-gamma subunits. The activated G proteins then bind to and activate numerous downstream effector proteins, which generate second messengers that mediate a broad range of cellular and physiological processes.

157-312 6.37e-03

D2-like dopamine receptors, member of the class A family of seven-transmembrane G protein-coupled receptors; Dopamine receptors are members of the class A G protein-coupled receptors that are involved in many neurological processes in the central nervous system (CNS). The neurotransmitter dopamine is the primary endogenous agonist for dopamine receptors. Dopamine receptors consist of at least five subtypes: D1, D2, D3, D4, and D5. The D1 and D5 subtypes are members of the D1-like family of dopamine receptors, whereas the D2, D3 and D4 subtypes are members of the D2-like family. The D1-like family receptors are coupled to G proteins of the G(s) family, which activate adenylate cyclase, causing cAMP formation and activation of protein kinase A. In contrast, activation of D2-like family receptors is linked to G proteins of the G(i) family, which inhibit adenylate cyclase. Dopamine receptors are major therapeutic targets for neurological and psychiatric disorders such as drug abuse, depression, schizophrenia, or Parkinson's disease.

242-306 6.70e-03

vasopressin receptor subtype 1A, member of the class A family of seven-transmembrane G protein-coupled receptors; V1a-type receptor is a G(q/11)-coupled receptor that mediates blood vessel constriction. Vasopressin (also known as arginine vasopressin or anti-diuretic hormone) is synthesized in the hypothalamus and is released from the posterior pituitary gland. The actions of vasopressin are mediated by the interaction of this hormone with three receptor subtypes: V1aR, V1bR, and V2R. These subtypes are differ in localization, function, and signaling pathways. Activation of V1aR and V1bR stimulate phospholipase C, while activation of V2R stimulates adenylate cyclase. Although vasopressin and oxytocin differ only by two amino acids and stimulate the same cAMP/PKA pathway, they have divergent physiological functions. Vasopressin is involved in regulating blood pressure and the balance of water and sodium ions, whereas oxytocin plays an important role in the uterus during childbirth and in lactation.

P2Y-like receptor and similar proteins, member of the class A family of seven-transmembrane G protein-coupled receptors; GPR34 is phylogenetically related to the P2Y family of purinergic G protein-coupled receptors. The P2Y receptor family is composed of eight subtypes, which are activated by naturally occurring extracellular nucleotides such as ATP, ADP, UTP, UDP, and UDP-glucose. GPR34 is shown to couple to G(i/o) protein and is highly expressed in microglia. Recently, lysophosphatidylserine has been identified as a ligand for GPR34. This group belongs to the class A G protein-coupled receptor superfamily, which all have a common structural architecture comprising of seven-transmembrane (TM) alpha-helices interconnected by three extracellular and three intracellular loops. A general feature of GPCR signaling is agonist-induced conformational changes in the receptors, which then activate the heterotrimeric G proteins. G-proteins regulate a variety of cellular functions including metabolic enzymes, ion channels, and transporters, among many others.

45-310 8.85e-03

cholecystokinin receptor type A, member of the class A family of seven-transmembrane G protein-coupled receptors; Cholecystokinin receptors (CCK-AR and CCK-BR) are a group of G-protein coupled receptors which bind the peptide hormones cholecystokinin (CCK) or gastrin. CCK, which facilitates digestion in the small intestine, and gastrin, a major regulator of gastric acid secretion, are highly similar peptides. Like gastrin, CCK is a naturally-occurring linear peptide that is synthesized as a preprohormone, then proteolytically cleaved to form a family of peptides with the common C-terminal sequence (Gly-Trp-Met-Asp-Phe-NH2), which is required for full biological activity. CCK-AR (type A, alimentary; also known as CCK1R) is found abundantly on pancreatic acinar cells and binds only sulfated CCK-peptides with very high affinity, whereas CCK-BR (type B, brain; also known as CCK2R), the predominant form in the brain and stomach, binds CCK or gastrin and discriminates poorly between sulfated and non-sulfated peptides. CCK is implicated in regulation of digestion, appetite control, and body weight, and is involved in neurogenesis via CCK-AR. There is some evidence to support that CCK and gastrin, via their receptors, are involved in promoting cancer development and progression, acting as growth and invasion factors.

47-130 9.03e-03

orphan G protein-coupled receptor 82, member of the class A family of seven-transmembrane G protein-coupled receptors; This subgroup represents the G-protein coupled receptor 82 of unknown function. GPR82 is a member of the rhodopsin-like, class A GPCRs, which is a widespread protein family that includes the light-sensitive rhodopsin as well as receptors for biogenic amines, lipids, nucleotides, odorants, peptide hormones, and a variety of other ligands. All GPCRs have a common structural architecture comprising of seven-transmembrane (TM) alpha-helices interconnected by three extracellular and three intracellular loops. A general feature of GPCR signaling is agonist-induced conformational changes in the receptors, leading to activation of the heterotrimeric G proteins, which consist of the guanine nucleotide-binding G-alpha subunit and the dimeric G-beta-gamma subunits. The activated G proteins then bind to and activate numerous downstream effector proteins, which generate second messengers that mediate a broad range of cellular and physiological processes.
