Type 1 periplasmic binding fold superfamily; Type 1 periplasmic binding fold superfamily. This model and hierarchy represent the ligand binding domains of the LacI family of transcriptional regulators, periplasmic binding proteins of the ABC-type transport systems, the family C G-protein couples receptors (GPCRs), membrane bound guanylyl cyclases including the family of natriuretic peptide receptors (NPRs), and the N-terminal leucine-isoleucine-valine binding protein (LIVBP)-like domains of the ionotropic glutamate receptors (iGluRs). In LacI-like transcriptional regulator and the bacterial periplasmic binding proteins, the ligands are monosaccharides, including lactose, ribose, fructose, xylose, arabinose, galactose/glucose and other sugars, with a few exceptions. Periplasmic sugar binding proteins are one of the components of ABC transporters and are involved in the active transport of water-soluble ligands. The LacI family of proteins consists of transcriptional regulators related to the lac repressor. In this case, the sugar binding domain binds a sugar which changes the DNA binding activity of the repressor domain. The periplasmic binding proteins are the primary receptors for chemotaxis and transport of many sugar based solutes. The core structures of periplasmic binding proteins are classified into two types, and they differ in number and order of beta strands: type 1 has six beta strands while type 2 has five beta strands per sub-domain. These two structural folds are thought to be distantly related via a common ancestor. Notably, while the N-terminal LIVBP-like domain of iGluRs belongs to the type 1 periplasmic-binding fold protein superfamily, the glutamate-binding domain of the iGluR is structurally similar to the type 2 periplasmic-binding fold.

 212-247 7.86e-04

Transmembrane domain of Ephrin Receptor A1 Protein Tyrosine Kinase; Ephrin receptors (EphRs) comprise the largest subfamily of receptor PTKs, and are classified into two classes (EphA and EphB), corresponding to binding preferences for either GPI-anchored ephrin-A ligands or transmembrane ephrin-B ligands. Vertebrates have ten EphA and six EphB receptors, which display promiscuous ligand interactions within each class. EphA1 has been associated with late-onset Alzheimer's disease and certain cancers such as colorectal and gastric carcinomas. EphRs contain an ephrin binding domain and two fibronectin repeats extracellularly, a single-span transmembrane (TM) domain, and a cytoplasmic tyr kinase domain. Binding of the ephrin ligand to EphR requires cell-cell contact since both are anchored to the plasma membrane. This allows ephrin/EphR dimers to form, leading to the activation of the intracellular tyr kinase domain. The resulting downstream signals occur bidirectionally in both EphR-expressing cells (forward signaling) and ephrin-expressing cells (reverse signaling). The main effect of ephrin/EphR interaction is cell-cell repulsion or adhesion. Ephrin/EphR signaling is important in neural development and plasticity, cell morphogenesis and proliferation, cell-fate determination, embryonic development, tissue patterning, and angiogenesis. The TM domain mediates dimerization.

 1-187 2.29e-133

ligand-binding domain of type C natriuretic peptide receptor; Ligand-binding domain of type C natriuretic peptide receptor (NPR-C). NPR-C is found in atrial, mesentery, placenta, lung, kidney, venous tissue, aortic smooth muscle, and aortic endothelial cells. The affinity of NPR-C for natriuretic peptides is ANP>CNP>BNP. The extracellular domain of NPR-C is about 30% identical to NPR-A and NPR-B. However, unlike the cyclase-linked receptors, it contains only 37 intracellular amino acids and no guanylyl cyclase activity. Major function of NPR-C is to clear natriuretic peptides from the circulation or extracellular surroundings through constitutive receptor-mediated internalization and degradation.

 1-185 1.24e-96

Ligand binding domain of natriuretic peptide receptor (NPR) family; Ligand binding domain of natriuretic peptide receptor (NPR) family which consists of three different subtypes: type A natriuretic peptide receptor (NPR-A, or GC-A), type B natriuretic peptide receptors (NPR-B, or GC-B), and type C natriuretic peptide receptor (NPR-C). There are three types of natriuretic peptide (NP) ligands specific to the receptors: atrial NP (ANP), brain or B-type NP (BNP), and C-type NP (CNP). The NP family is thought to have arisen through gene duplication during evolution and plays an essential role in cardiovascular and body fluid homeostasis. ANP and BNP bind mainly to NPR-A, while CNP binds specifically to NPR-B. Both NPR-A and NPR-B have guanylyl cyclase catalytic activity and produces intracellular secondary messenger cGMP in response to peptide-ligand binding. Consequently, the NPR-A activation results in vasodilation and inhibition of vascular smooth muscle cell proliferation. NPR-C acts as the receptor for all the three members of NP family, and functions as a clearance receptor. Unlike NPR-A and -B, NPR-C lacks an intracellular guanylyl cyclase domain and is thought to exert biological actions by sequestration of released natriuretic peptides and/or inhibition of adenylyl cyclase.

 1-186 1.19e-63

ligand-binding domain of membrane guanylyl-cyclase receptors; Ligand-binding domain of membrane guanylyl-cyclase receptors. Membrane guanylyl cyclases (GC) have a single membrane-spanning region and are activated by endogenous and exogenous peptides. This family can be divided into three major subfamilies: the natriuretic peptide receptors (NPRs), sensory organ-specific membrane GCs, and the enterotoxin/guanylin receptors. The binding of peptide ligands to the receptor results in the activation of the cytosolic catalytic domain. Three types of NPRs have been cloned from mammalian tissues: NPR-A/GC-A, NPR-B/ GC-B, and NPR-C. In addition, two of the GCs, GC-D and GC-G, appear to be pseudogenes in humans. Atrial natriuretic peptide (ANP) and brain natriuretic peptide (BNP) are produced in the heart, and both bind to the NPR-A. NPR-C, also termed the clearance receptor, binds each of the natriuretic peptides and can alter circulating levels of these peptides. The ligand binding domain of the NPRs exhibits strong structural similarity to the type 1 periplasmic binding fold protein family.

Ligand-binding domain of type A natriuretic peptide receptor; Ligand-binding domain of type A natriuretic peptide receptor (NPR-A). NPR-A is one of three known single membrane-spanning natriuretic peptide receptors that regulate blood volume, blood pressure, ventricular hypertrophy, pulmonary hypertension, fat metabolism, and long bone growth. In mammals there are three natriuretic peptides: ANP, BNP, and CNP. NPR-A is highly expressed in kidney, adrenal, terminal ileum, adipose, aortic, and lung tissues. The rank order of NPR-A activation by natriuretic peptides is ANP>BNP>>CNP. Single allele-inactivating mutations in the promoter of human NPR-A are associated with hypertension and heart failure.

ligand-binding domain of type B natriuretic peptide receptor; Ligand-binding domain of type B natriuretic peptide receptor (NPR-B). NPR-B is one of three known single membrane-spanning natriuretic peptide receptors that have been identified. Natriuretic peptides are family of structurally related but genetically distinct hormones/paracrine factors that regulate blood volume, blood pressure, ventricular hypertrophy, pulmonary hypertension, fat metabolism, and long bone growth. In mammals there are three natriuretic peptides: ANP, BNP, and CNP. Like NPR-A (or GC-A), NPR-B (or GC-B) is a transmembrane guanylyl cyclase, an enzyme that catalyzes the synthesis of cGMP. NPR-B is the predominant natriuretic peptide receptor in the brain. The rank of order activation of NPR-B by natriuretic peptides is CNP>>ANP>BNP. Homozygous inactivating mutations in human NPR-B cause a form of short-limbed dwarfism known as acromesomelic dysplasia type Maroteaux.

ligand-binding domain of family C G-protein couples receptors (GPCRs), membrane bound guanylyl cyclases such as natriuretic peptide receptors (NPRs), and N-terminal leucine/isoleucine/valine-binding protein (LIVBP)-like domain of ionotropic glutamate rece; This CD represents the ligand-binding domain of the family C G-protein couples receptors (GPCRs), membrane bound guanylyl cyclases such as the family of natriuretic peptide receptors (NPRs), and the N-terminal leucine-isoleucine-valine binding protein (LIVBP)-like domain of the ionotropic glutamate receptors, all of which are structurally similar and related to the periplasmic-binding fold type 1 family. The family C GPCRs consists of metabotropic glutamate receptor (mGluR), a calcium-sensing receptor (CaSR), gamma-aminobutyric acid receptor (GABAbR), the promiscuous L-alpha-amino acid receptor GPR6A, families of taste and pheromone receptors, and orphan receptors. Truncated splicing variants of the orphan receptors are not included in this CD. The family C GPCRs are activated by endogenous agonists such as amino acids, ions, and sugar based molecules. Their amino terminal ligand-binding region is homologous to the bacterial leucine-isoleucine-valine binding protein (LIVBP) and a leucine binding protein (LBP). The ionotropic glutamate receptors (iGluRs) have an integral ion channel and are subdivided into three major groups based on their pharmacology and structural similarities: NMDA receptors, AMPA receptors, and kainate receptors. The family of membrane bound guanylyl cyclases is further divided into three subfamilies: the ANP receptor (GC-A)/C-type natriuretic peptide receptor (GC-B), the heat-stable enterotoxin receptor (GC-C)/sensory organ specific membrane GCs such as retinal receptors (GC-E, GC-F), and olfactory receptors (GC-D and GC-G).

Ligand-binding domain of membrane bound guanylyl cyclases; Ligand-binding domain of membrane bound guanylyl cyclases (GCs), which are known to be activated by sperm-activating peptides (SAPs), such as speract or resact. These ligand peptides are released by a range of invertebrates to stimulate the metabolism and motility of spermatozoa and are also potent chemoattractants. These GCs contain a single transmembrane segment, an extracellular ligand binding domain, and intracellular protein kinase-like and cyclase catalytic domains. GCs of insect and nematodes, which exhibit high sequence similarity to the speract receptor are also included in this model.

GC-G appears to be a pseudogene in human. Furthermore, in contrast to the other orphan receptor GCs, GC-G has a broad tissue distribution in rat, including lung, intestine, kidney, and skeletal muscle.

ligand-binding domain of GABAb receptors, which are metabotropic transmembrane receptors for gamma-aminobutyric acid (GABA); Ligand-binding domain of GABAb receptors, which are metabotropic transmembrane receptors for gamma-aminobutyric acid (GABA). GABA is the major inhibitory neurotransmitter in the mammalian CNS and, like glutamate and other transmitters, acts via both ligand gated ion channels (GABAa receptors) and G-protein coupled receptors (GABAb receptor or GABAbR). GABAa receptors are members of the ionotropic receptor superfamily which includes alpha-adrenergic and glycine receptors. The GABAb receptor is a member of a receptor superfamily which includes the mGlu receptors. The GABAb receptor is coupled to G alpha-i proteins, and activation causes a decrease in calcium, an increase in potassium membrane conductance, and inhibition of cAMP formation. The response is thus inhibitory and leads to hyperpolarization and decreased neurotransmitter release, for example.

 1-177 4.45e-06

ligand-binding domain of membrane guanylyl cyclases (GC-D, GC-E, and GC-F) that are specifically expressed in sensory tissues; This group includes the ligand-binding domain of membrane guanylyl cyclases (GC-D, GC-E, and GC-F) that are specifically expressed in sensory tissues. They share a similar topology with an N-terminal extracellular ligand-binding domain, a single transmembrane domain, and a C-terminal cytosolic region that contains kinase-like and catalytic domains. GC-D is specifically expressed in a subpopulation of olfactory sensory neurons. GC-E and GC-F are colocalized within the same photoreceptor cells of the retina and have important roles in phototransduction. Unlike the other family members, GC-E and GC-F have no known extracellular ligands. Instead, they are activated under low calcium conditions by guanylyl cyclase activating proteins called GCAPs. GC-D expressing neurons have been implicated in pheromone detection and GC-D is phylogenetically more similar to the Ca2+-regulated GC-E and GC-F than to receptor GC-A, -B and -C which are activated by peptide ligands. Moreover, these olfactory GCs and retinal GCs share characteristic sequence similarity in a regulatory domain that is involved in the binding of GCAPs, suggesting GC-D activity may be regulated by an unknown extracellular ligand and intracellular Ca2+. Rodent GC-D-expressing neurons have been implicated in pheromone detection and were recently shown to respond to atmospheric CO2 which is an olfactory stimulus for many invertebrates and regulates some insect innate behavior, such as the location of food and hosts.

Transmembrane domain of Ephrin Receptor A1 Protein Tyrosine Kinase; Ephrin receptors (EphRs) comprise the largest subfamily of receptor PTKs, and are classified into two classes (EphA and EphB), corresponding to binding preferences for either GPI-anchored ephrin-A ligands or transmembrane ephrin-B ligands. Vertebrates have ten EphA and six EphB receptors, which display promiscuous ligand interactions within each class. EphA1 has been associated with late-onset Alzheimer's disease and certain cancers such as colorectal and gastric carcinomas. EphRs contain an ephrin binding domain and two fibronectin repeats extracellularly, a single-span transmembrane (TM) domain, and a cytoplasmic tyr kinase domain. Binding of the ephrin ligand to EphR requires cell-cell contact since both are anchored to the plasma membrane. This allows ephrin/EphR dimers to form, leading to the activation of the intracellular tyr kinase domain. The resulting downstream signals occur bidirectionally in both EphR-expressing cells (forward signaling) and ephrin-expressing cells (reverse signaling). The main effect of ephrin/EphR interaction is cell-cell repulsion or adhesion. Ephrin/EphR signaling is important in neural development and plasticity, cell morphogenesis and proliferation, cell-fate determination, embryonic development, tissue patterning, and angiogenesis. The TM domain mediates dimerization.

ligand-binding domain of the membrane guanylyl cyclase C; Ligand-binding domain of the membrane guanylyl cyclase C (GC-C or StaR). StaR is a key receptor for the STa (Escherichia coli Heat Stable enterotoxin), a potent stimulant of intestinal chloride and bicarbonate secretion that cause acute secretory diarrhea. The catalytic domain of the STa/guanylin receptor type membrane GC is highly similar to those of the natriuretic peptide receptor (NPR) type and sensory organ-specific type membrane GCs (GC-D, GC-E and GC-F). The GC-C receptor is mainly expressed in the intestine of most vertebrates, but is also found in the kidney and other organs. Moreover, GC-C is activated by guanylin and uroguanylin, endogenous peptide ligands synthesized in the intestine and kidney. Consequently, the receptor activation results in increased cGMP levels and phosphorylation of the CFTR chloride channel and secretion.
