222-543 0e+00

class F frizzled subfamily 9, member of 7-transmembrane G protein-coupled receptors; This group includes subfamily 9 of the frizzled (FZD) family of seven transmembrane-spanning proteins, which constitute a novel and separate class of GPCRs, and its closely related proteins. This class F protein family consists of 10 isoforms (FZD1-10) in mammals. The FZDs are activated by the wingless/int-1 (WNT) family of secreted lipoglycoproteins and preferentially couple to stimulatory G proteins of the Gs family, which activate adenylate cyclase, but can also couple to G proteins of the Gi/Gq families. In the WNT/beta-catenin signaling pathway, the WNT ligand binds to FZD and a lipoprotein receptor-related protein (LRP) co-receptor. This leads to the stabilization and translocation of beta-catenin to the nucleus, where it induces the activation of TCF/LEF family transcription factors. The conserved cytoplasmic motif of FZD, Lys-Thr-X-X-X-Trp, is required for activation of the WNT/beta-catenin pathway, and for membrane localization and phosphorylation of Dsh (dishevelled) protein, a key component of the WNT pathway that relays the WNT signals from the activated receptor to downstream effector proteins. The WNT pathway plays a critical role in many developmental processes, such as cell-fate determination, cell proliferation, neural patterning, stem cell renewal, tissue homeostasis and repair, and tumorigenesis, among many others.

36-162 5.90e-95

Cysteine-rich Wnt-binding domain (CRD) of the frizzled 9 (Fz9) receptor; The cysteine-rich domain (CRD) is an essential extracellular portion of the frizzled 9 (Fz9) receptor, and is required for binding Wnt proteins, which play fundamental roles in many aspects of early development, such as cell and tissue polarity, neural synapse formation, and the regulation of proliferation. Fz proteins serve as Wnt receptors for multiple signal transduction pathways, including both beta-catenin dependent and -independent cellular signaling, as well as the planar cell polarity pathway and Ca(2+) modulating signaling pathway. CRD containing Fzs have been found in diverse species from amoebas to mammals. 10 different frizzled proteins are found in vertebrata. Fz9 may play a signaling role in lymphoid development and maturation, particularly at points where B cells undergo self-renewal prior to further differentiation.

223-545 4.42e-179

Frizzled/Smoothened family membrane region; This family contains the membrane spanning region of frizzled and smoothened receptors. This membrane region is predicted to contain seven transmembrane alpha helices. Proteins related to Drosophila frizzled are receptors for Wnt (mediating the beta-catenin signalling pathway), but also the planar cell polarity (PCP) pathway and the Wnt/calcium pathway. The predominantly alpha-helical Cys-rich ligand-binding region (CRD) of Frizzled is both necessary and sufficient for Wnt binding. The smoothened receptor mediates hedgehog signalling.

222-543 0e+00

class F frizzled subfamily 9, member of 7-transmembrane G protein-coupled receptors; This group includes subfamily 9 of the frizzled (FZD) family of seven transmembrane-spanning proteins, which constitute a novel and separate class of GPCRs, and its closely related proteins. This class F protein family consists of 10 isoforms (FZD1-10) in mammals. The FZDs are activated by the wingless/int-1 (WNT) family of secreted lipoglycoproteins and preferentially couple to stimulatory G proteins of the Gs family, which activate adenylate cyclase, but can also couple to G proteins of the Gi/Gq families. In the WNT/beta-catenin signaling pathway, the WNT ligand binds to FZD and a lipoprotein receptor-related protein (LRP) co-receptor. This leads to the stabilization and translocation of beta-catenin to the nucleus, where it induces the activation of TCF/LEF family transcription factors. The conserved cytoplasmic motif of FZD, Lys-Thr-X-X-X-Trp, is required for activation of the WNT/beta-catenin pathway, and for membrane localization and phosphorylation of Dsh (dishevelled) protein, a key component of the WNT pathway that relays the WNT signals from the activated receptor to downstream effector proteins. The WNT pathway plays a critical role in many developmental processes, such as cell-fate determination, cell proliferation, neural patterning, stem cell renewal, tissue homeostasis and repair, and tumorigenesis, among many others.

class F frizzled subfamilies 4, 9, 10, and related proteins; member of 7-transmembrane G protein-coupled receptors; This group includes subfamilies 4, 9 and 10 of the frizzled (FZD) family of seven transmembrane-spanning proteins, which constitute a novel and separate class of GPCRs, and their closely related proteins. This class F protein family consists of 10 isoforms (FZD1-10) in mammals. The FZDs are activated by the wingless/int-1 (WNT) family of secreted lipoglycoproteins and preferentially couple to stimulatory G proteins of the Gs family, which activate adenylate cyclase, but can also couple to G proteins of the Gi/Gq families. In the WNT/beta-catenin signaling pathway, the WNT ligand binds to FZD and a lipoprotein receptor-related protein (LRP) co-receptor. This leads to the stabilization and translocation of beta-catenin to the nucleus, where it induces the activation of TCF/LEF family transcription factors. The conserved cytoplasmic motif of FZD, Lys-Thr-X-X-X-Trp, is required for activation of the WNT/beta-catenin pathway, and for membrane localization and phosphorylation of Dsh (dishevelled) protein, a key component of the WNT pathway that relays the WNT signals from the activated receptor to downstream effector proteins. The WNT pathway plays a critical role in many developmental processes, such as cell-fate determination, cell proliferation, neural patterning, stem cell renewal, tissue homeostasis and repair, and tumorigenesis, among many others.

223-545 4.42e-179

Frizzled/Smoothened family membrane region; This family contains the membrane spanning region of frizzled and smoothened receptors. This membrane region is predicted to contain seven transmembrane alpha helices. Proteins related to Drosophila frizzled are receptors for Wnt (mediating the beta-catenin signalling pathway), but also the planar cell polarity (PCP) pathway and the Wnt/calcium pathway. The predominantly alpha-helical Cys-rich ligand-binding region (CRD) of Frizzled is both necessary and sufficient for Wnt binding. The smoothened receptor mediates hedgehog signalling.

class F frizzled subfamilies 5, 8 and related proteins; member of 7-transmembrane G protein-coupled receptors; This group includes subfamilies 5 and 8 of the frizzled (FZD) family of seven transmembrane-spanning proteins, which constitute a novel and separate class of GPCRs, as well as their closely related proteins. This class F protein family consists of 10 isoforms (FZD1-10) in mammals. The FZDs are activated by the wingless/int-1 (WNT) family of secreted lipoglycoproteins and preferentially couple to stimulatory G proteins of the Gs family, which activate adenylate cyclase, but can also couple to G proteins of the Gi/Gq families. In the WNT/beta-catenin signaling pathway, the WNT ligand binds to FZD and a lipoprotein receptor-related protein (LRP) co-receptor. This leads to the stabilization and translocation of beta-catenin to the nucleus, where it induces the activation of TCF/LEF family transcription factors. The conserved cytoplasmic motif of FZD, Lys-Thr-X-X-X-Trp, is required for activation of the WNT/beta-catenin pathway, and for membrane localization and phosphorylation of Dsh (dishevelled) protein, a key component of the WNT pathway that relays the WNT signals from the activated receptor to downstream effector proteins. The WNT pathway plays a critical role in many developmental processes, such as cell-fate determination, cell proliferation, neural patterning, stem cell renewal, tissue homeostasis and repair, and tumorigenesis, among many others.

223-541 1.62e-140

class F frizzled/smoothened family, member of the 7-transmembrane G protein-coupled receptor superfamily; The class F G protein-coupled receptors includes the frizzled (FZD) family of seven-transmembrane proteins consisting of 10 isoforms (FZD1-10) in mammals. The FZDs are activated by the wingless/int-1 (WNT) family of secreted lipoglycoproteins and preferentially couple to stimulatory G proteins of the Gs family, which activate adenylate cyclase, but can also couple to G proteins of the Gi/Gq families. In the WNT/beta-catenin signaling pathway, the WNT ligand binds to FZD and a lipoprotein receptor-related protein (LRP) co-receptor. This leads to the stabilization and translocation of beta-catenin to the nucleus, where it induces the activation of TCF/LEF family transcription factors. The conserved cytoplasmic motif of FZD, Lys-Thr-X-X-X-Trp, is required for activation of the WNT/beta-catenin pathway, and for membrane localization and phosphorylation of Dsh (dishevelled) protein, a key component of the WNT pathway that relays the WNT signals from the activated receptor to downstream effector proteins. Also included in the class F family is the closely related smoothened (SMO), which is a transmembrane G protein-coupled receptor that acts as the transducer of the hedgehog (HH) signaling pathway. SMO is activated by the hedgehog (HH) family of proteins acting on the 12-transmembrane domain receptor patched (PTCH), which constitutively inhibits SMO. Thus, in the absence of HH proteins, PTCH inhibits SMO signaling. On the other hand, binding of HH to the PTCH receptor activates its internalization and degradation, thereby releasing the PTCH inhibition of SMO. This allows SMO to trigger intracellular signaling and the subsequent activation of the Gli family of zinc finger transcriptional factors and induction of HH target gene expression (PTCH, Gli1, cyclin, Bcl-2, etc). The WNT and HH signaling pathways play critical roles in many developmental processes, such as cell-fate determination, cell proliferation, neural patterning, stem cell renewal, tissue homeostasis and repair, and tumorigenesis, among many others.

class F frizzled subfamily 7, member of 7-transmembrane G protein-coupled receptors; This group includes subfamily 7 of the frizzled (FZD) family of seven transmembrane-spanning proteins, which constitute a novel and separate class of G-protein coupled receptors. This class F protein family consists of 10 isoforms (FZD1-10) in mammals. The FZDs are activated by the wingless/int-1 (WNT) family of secreted lipoglycoproteins and preferentially couple to stimulatory G proteins of the Gs family, which activate adenylate cyclase, but can also couple to G proteins of the Gi/Gq families. In the WNT/beta-catenin signaling pathway, the WNT ligand binds to FZD and a lipoprotein receptor-related protein (LRP) co-receptor. This leads to the stabilization and translocation of beta-catenin to the nucleus, where it induces the activation of TCF/LEF family transcription factors. The conserved cytoplasmic motif of FZD, Lys-Thr-X-X-X-Trp, is required for activation of the WNT/beta-catenin pathway, and for membrane localization and phosphorylation of Dsh (dishevelled) protein, a key component of the WNT pathway that relays the WNT signals from the activated receptor to downstream effector proteins. The WNT pathway plays a critical role in many developmental processes, such as cell-fate determination, cell proliferation, neural patterning, stem cell renewal, tissue homeostasis and repair, and tumorigenesis, among many others

Cysteine-rich Wnt-binding domain (CRD) of the frizzled 9 (Fz9) receptor; The cysteine-rich domain (CRD) is an essential extracellular portion of the frizzled 9 (Fz9) receptor, and is required for binding Wnt proteins, which play fundamental roles in many aspects of early development, such as cell and tissue polarity, neural synapse formation, and the regulation of proliferation. Fz proteins serve as Wnt receptors for multiple signal transduction pathways, including both beta-catenin dependent and -independent cellular signaling, as well as the planar cell polarity pathway and Ca(2+) modulating signaling pathway. CRD containing Fzs have been found in diverse species from amoebas to mammals. 10 different frizzled proteins are found in vertebrata. Fz9 may play a signaling role in lymphoid development and maturation, particularly at points where B cells undergo self-renewal prior to further differentiation.

The FZDs are activated by the wingless/int-1 (WNT) family of secreted lipoglycoproteins and preferentially couple to stimulatory G proteins of the Gs family, which activate adenylate cyclase, but can also couple to G proteins of the Gi/Gq families. In the WNT/beta-catenin signaling pathway, the WNT ligand binds to FZD and a lipoprotein receptor-related protein (LRP) co-receptor. This leads to the stabilization and translocation of beta-catenin to the nucleus, where it induces the activation of TCF/LEF family transcription factors. The conserved cytoplasmic motif of FZD, Lys-Thr-X-X-X-Trp, is required for activation of the WNT/beta-catenin pathway, and for membrane localization and phosphorylation of Dsh (dishevelled) protein, a key component of the WNT pathway that relays the WNT signals from the activated receptor to downstream effector proteins. The WNT pathway plays a critical role in many developmental processes, such as cell-fate determination, cell proliferation, neural patterning, stem cell renewal, tissue homeostasis and repair, and tumorigenesis, among many others.

Cysteine-rich Wnt-binding domain (CRD) of receptors similar to frizzled 9; The cysteine-rich domain (CRD) is an essential extracellular portion of the frizzled 9 (Fz9) and frizzled 10 (Fz10) receptors, and similar proteins. This domain is required for binding Wnt proteins, which play fundamental roles in many aspects of early development, such as cell and tissue polarity, neural synapse formation, and the regulation of proliferation. Fz proteins serve as Wnt receptors for multiple signal transduction pathways, including both beta-catenin dependent and -independent cellular signaling, as well as the planar cell polarity pathway and Ca(2+) modulating signaling pathway. The CRD domain is well conserved in metazoans - 10 frizzled proteins have been identified in mammals, 4 in Drosophila and 3 in Caenorhabditis elegans. Very little is known about the mechanism by which CRD domains interact with their ligands. The domain contains 10 conserved cysteines.

CRD containing Fzs have been found in diverse species from amoebas to mammals. 10 different frizzled proteins are found in vertebrata. Frizzled 4 (Fz4) activates the Ca(2+)/calmodulin-dependent protein kinase II and protein kinase C of the Wnt/Ca(2+) signaling pathway during retinal angiogenesis. Mutations in Fz4 lead to familial exudative vitreoretinopathy (FEVR), a hereditary ocular disorder characterized by failure of the peripheral retinal vascularization. In addition, the interplay between Fz4 and norrin as a receptor-ligand pair plays an important role in vascular development in the retina and inner ear in a Wnt-independent manner.

235-538 2.08e-52

class F smoothened family membrane region, a homolog of frizzled receptors; This group represents smoothened (SMO), a transmembrane G protein-coupled receptor that acts as the transducer of the hedgehog (HH) signaling pathway. SMO is activated by the hedgehog (HH) family of proteins acting on the 12-transmembrane domain receptor patched (PTCH), which constitutively inhibits SMO. Thus, in the absence of HH proteins, PTCH inhibits SMO signaling. On the other hand, binding of HH to the PTCH receptor activates its internalization and degradation, thereby releasing the PTCH inhibition of SMO. This allows SMO to trigger intracellular signaling and the subsequent activation of the Gli family of zinc finger transcriptional factors and induction of HH target gene expression (PTCH, Gli1, cyclin, Bcl-2, etc). SMO is closely related to the frizzled (FZD) family of seven transmembrane-spanning proteins, which constitute a novel and separate family of G-protein coupled receptors. The FZDs are activated by the wingless/int-1 (WNT) family of secreted lipoglycoproteins and preferentially couple to stimulatory G proteins of the Gs family, which activate adenylate cyclase, but can also couple to G proteins of the Gi/Gq families. In the WNT/beta-catenin signaling pathway, the WNT ligand binds to FZD and a lipoprotein receptor-related protein (LRP) co-receptor. This leads to the stabilization and translocation of beta-catenin to the nucleus, where it induces the activation of TCF/LEF family transcription factors. The WNT and HH signaling pathways play critical roles in many developmental processes, such as cell-fate determination, cell proliferation, neural patterning, stem cell renewal, tissue homeostasis and repair, and tumorigenesis, among many others.

Cysteine-rich Wnt-binding domain (CRD) of receptors similar to frizzled 5; The cysteine-rich domain (CRD) is an essential extracellular portion of the frizzled 5 (Fz5) and frizzled 8 (Fz8) receptors, and similar proteins. This domain is required for binding Wnt proteins, which play fundamental roles in many aspects of early development, such as cell and tissue polarity, neural synapse formation, and the regulation of proliferation. Fz proteins serve as Wnt receptors for multiple signal transduction pathways, including both beta-catenin dependent and -independent cellular signaling, as well as the planar cell polarity pathway and Ca(2+) modulating signaling pathway. The CRD domain is well conserved in metazoans - 10 frizzled proteins have been identified in mammals, 4 in Drosophila and 3 in Caenorhabditis elegans. Very little is known about the mechanism by which CRD domains interact with their ligands. The domain contains 10 conserved cysteines.

CRD_domain cysteine-rich domain, also known as Fz (frizzled) domain; CRD_FZ is an essential component of a number of cell surface receptors, which are involved in multiple signal transduction pathways, particularly in modulating the activity of the Wnt proteins, which play a fundamental role in the early development of metazoans. CRD is also found in secreted frizzled related proteins (SFRPs), which lack the transmembrane segment found in the frizzled protein. The CRD domain is also present in the alpha-1 chain of mouse type XVIII collagen, in carboxypeptidase Z, several receptor tyrosine kinases, and the mosaic transmembrane serine protease corin. The CRD domain is well conserved in metazoans - 10 frizzled proteins have been identified in mammals, 4 in Drosophila and 3 in Caenorhabditis elegans. CRD domains have also been identified in multiple tandem copies in a Dictyostelium discoideum protein. Very little is known about the mechanism by which CRD domains interact with their ligands. The domain contains 10 conserved cysteines.

SFRPs antagonize the activation of Wnt signaling by binding to the CRDs domains of frizzled (Fz) proteins, thereby preventing Wnt proteins from binding to these receptors. SFRPs are also known to have functions unrelated to Wnt, as enhancers of procollagen cleavage by the TLD proteinases. SFRPs and Fz proteins both contain CRD domains, but SFRPs lack the seven-pass transmembrane domain which is an integral part of Fzs.

SFRPs and Fz proteins both contain CRD domains, but SFRPs lack the seven-pass transmembrane domain which is an integral part of Fzs. As a Wnt antagonist, SFRP2 regulates Nkx2.2 expression in the ventral spinal cord and anteroposterior axis elongation. SFRP2 also has a Wnt-independent function as an enhancer of procollagen cleavage by the TLD proteinases. SFRP2 binds both procollagen and TLD, thus facilitating the enzymatic reaction by bringing together the proteinase and its substrate.

Cysteine-rich domain (CRD) of LIN_17; A cysteine-rich domain (CRD) is an essential component of a number of cell surface receptors, which are involved in multiple signal transduction pathways, particularly in modulating the activity of the Wnt proteins, which play a fundamental role in the early development of metazoans. CRD is also found in secreted frizzled related proteins (SFRPs), which lack the transmembrane segment found in the frizzled protein. The CRD domain is also present in the alpha-1 chain of mouse type XVIII collagen, in carboxypeptidase Z, several receptor tyrosine kinases, and the mosaic transmembrane serine protease corin. The CRD domain is well conserved in metazoans - 10 frizzled proteins have been identified in mammals, 4 in Drosophila and 3 in Caenorhabditis elegans. CRD domains have also been identified in multiple tandem copies in a Dictyostelium discoideum protein. Very little is known about the mechanism by which CRD domains interact with their ligands. The domain contains 10 conserved cysteines. The protein lin-17 is involved in cell type specification during Caenorhabditis elegans vulval development.

SFRPs antagonize the activation of Wnt signaling by binding to the CRD domains of frizzled proteins (Fz), thereby preventing Wnt proteins from binding to these receptors. SFRPs are also known to have functions unrelated to Wnt, as enhancers of procollagen cleavage by the TLD proteinases. SFRPs and Fz proteins both contain CRD domains, but SFRPs lack the seven-pass transmembrane domain which is an integral part of Fzs. SFRP3 regulates Wnt signaling activity in bone development and homeostasis. It is also involved in the control of planar cell polarity.

Cysteine-rich domain of the crescent protein; The cysteine-rich domain (CRD) is an essential part of the crescent protein, a member of the secreted frizzled-related protein (SFRP) family, which regulates convergent extension movements (CEMs) during gastrulation and neurulation. Xenopus laevis crescent efficiently forms inhibitory complexes with Wnt5a and Wnt11, but this effect is cancelled in the presence of another member of the SFRP family, Frzb1. A potential role for Crescent in head formation is to regulate a non-canonical Wnt pathway positively in the adjacent posterior mesoderm, and negatively in the overlying anterior neuroectoderm.

Cysteine-rich domain of carboxypeptidase Z, a member of the carboxypeptidase E family; The cysteine-rich-domain (CRD) is an essential part of carboxypeptidase Z, a member of the carboxypeptidase E family of metallocarboxypeptidases. This is a group of Zn-dependent enzymes implicated in the intra- and extracellular processing of proteins. Carboxypeptidase Z removes C-terminal basic amino acid residues from its substrates, particularly arginine. The CRD acts as a ligand-binding domain for Wnts involved in developmental processes. CPZ binds and may process Wnt-4, CPZ has also been found to enhance the induction of the homeobox gene Cdx1. During vertebrate embryogenesis, the CRD of CPZ upregulates Pax3, a Wnt reporter gene essential for patterning of somites and limb development.

230-455 1.10e-06

adhesion receptors, subfamily B2 of the class B family of seven-transmembrane G protein-coupled receptors; The B2 subfamily of class B GPCRs consists of cell-adhesion receptors with 33 members in humans and vertebrates. The adhesion receptors are characterized by the presence of large N-terminal extracellular domains containing a variety of structural motifs, which play critical roles in cell-cell adhesion and cell-matrix interactions, linked to a class B seven-transmembrane domain. These include, for example, EGF (epidermal growth factor)-like domains in CD97, Celsr1 (cadherin family member), Celsr2, Celsr3, EMR1 (EGF-module-containing mucin-like hormone receptor-like 1), EMR2, EMR3, and Flamingo; two laminin A G-type repeats and nine cadherin domains in Flamingo and its human orthologs Celsr1, Celsr2 and Celsr3; olfactomedin-like domains in the latrotoxin receptors; and five or four thrombospondin type 1 repeats in BAI1 (brain-specific angiogenesis inhibitor 1), BAI2 and BAI3. Furthermore, almost all adhesion receptors, except GPR123, contain an evolutionarily conserved GPCR- autoproteolysis inducing (GAIN) domain that undergoes autoproteolytic processing at the GPCR proteolysis site (GPS) motif located immediately N-terminal to the first transmembrane region, to generate N- and C-terminal fragments (NTF and CTF), which may serve important biological functions.

240-455 4.73e-06

class B family of seven-transmembrane G protein-coupled receptors; The class B of seven-transmembrane GPCRs is classified into three major subfamilies: subfamily B1 (secretin-like receptor family), B2 (adhesion family), and B3 (Methuselah-like family). The class B receptors have been identified in all the vertebrates, from fishes to mammals, as well as invertebrates including Caenorhabditis elegans and Drosophila melanogaster, but are not present in plants, fungi or prokaryotes. The B1 subfamily comprises receptors for polypeptide hormones of 27-141 amino-acid residues such as secretin, glucagon, glucagon-like peptide (GLP), calcitonin gene-related peptide, parathyroid hormone (PTH), and corticotropin-releasing factor. These receptors contain the large N-terminal extracellular domain (ECD), which plays a critical role in hormone recognition by binding to the C-terminal portion of the peptide. On the other hand, the N-terminal segment of the hormone induces receptor activation by interacting with the receptor transmembrane domains and connecting extracellular loops, triggering intracellular signaling pathways. All members of the subfamily B1 receptors preferentially couple to G proteins of G(s) family, which positively stimulate adenylate cyclase, leading to increased intracellular cAMP formation and calcium influx. The subfamily B2 consists of cell-adhesion receptors with 33 members in humans and vertebrates. The adhesion receptors are characterized by the presence of large N-terminal extracellular domains containing a variety of structural motifs, which play critical roles in cell-cell adhesion and cell-matrix interactions, linked to a class B seven-transmembrane domain. These include, for example, EGF (epidermal growth factor)-like domains in CD97, Celsr1 (cadherin family member), Celsr2, Celsr3, EMR1 (EGF-module-containing mucin-like hormone receptor-like 1), EMR2, EMR3, and Flamingo; two laminin A G-type repeats and nine cadherin domains in Flamingo and its human orthologs Celsr1, Celsr2 and Celsr3; olfactomedin-like domains in the latrotoxin receptors; and five or four thrombospondin type 1 repeats in BAI1 (brain-specific angiogenesis inhibitor 1), BAI2 and BAI3. Almost all adhesion receptors, except GPR123, contain an evolutionarily conserved GPCR- autoproteolysis inducing (GAIN) domain that undergoes autoproteolytic processing at the GPCR proteolysis site (GPS) motif located immediately N-terminal to the first transmembrane region, to generate N- and C-terminal fragments (NTF and CTF), which may serve important biological functions. Furthermore, the subfamily B3 includes Methuselah (Mth) protein, which was originally identified in Drosophila as a GPCR affecting stress resistance and aging, and its closely related proteins.

308-469 9.35e-04

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.

Cysteine-rich domain of tyrosine kinase-like orphan receptors; The cysteine-rich domain (CRD) is an essential part of the tyrosine kinase-like orphan receptor (Ror) proteins, a conserved family of tyrosine kinases that function in various processes, including neuronal and skeletal development, cell polarity, and cell movement. Ror proteins are receptors of Wnt proteins, which are key players in a number of fundamental cellular processes in embryogenesis and postnatal development. In different cellular contexts, Ror proteins can either activate or repress transcription of Wnt target genes, and can modulate Wnt signaling by sequestering Wnt ligands. In addition, a number of Wnt-independent functions have been proposed for both Ror1 and Ror2.

Methuselah-like subfamily B3, member of the class B family of seven-transmembrane G protein-coupled receptors; The subfamily B3 of class B GPCRs consists of Methuselah (Mth) and its closely related proteins found in bilateria. Mth was originally identified in Drosophila as a GPCR affecting stress resistance and aging. In addition to the seven transmembrane helices, Mth contains an N-terminal extracellular domain involved in ligand binding, and a third intracellular loop (IC3) required for the specificity of G-protein coupling. Drosophila Mth mutants showed an increase in average lifespan by 35% and greater resistance to a variety of stress factors, including starvation, high temperature, and paraquat-induced oxidative toxicity. Moreover, mutations in two endogenous peptide ligands of Methuselah, Stunted A and B, showed an increased in lifespan and resistance to oxidative stress induced by dietary paraquat. These results strongly suggest that the Stunted-Methuselah system plays important roles in stress response and aging.

Cysteine-rich domain of the smoothened receptor (Smo) integral membrane protein; The cysteine-rich domain (CRD) is part of the smoothened receptor (Smo), an integral membrane protein and one of the key players in the Hedgehog (Hh) signaling pathway, critical for development, cell growth and migration, as well as stem cell maintenance. The CRD of Smo is conserved in vertebrates and can also be identified in invertebrates. The precise function of the CRD in Smo is unknown. Mutations in the Drosophila CRD disrupt Smo activity in vivo, while deletion of the CRD in mammalian cells does not seem to affect the activity of overexpressed Smo.
