retinoic acid-induced protein 3 [Rattus norvegicus]

Protein Classification

G protein-coupled receptor family protein; olfactory receptor subfamily 2A protein( domain architecture ID 11607145)

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 (OR) subfamily 2A protein, such as human olfactory receptor 2A2 and related proteins in other mammals and sauropsids; ORs play a central role in olfaction, the sense of smell, and belong to the class A rhodopsin-like family of seven-transmembrane G protein-coupled receptors (7TM GPCRs)

29-273 6.99e-139

retinoic acid-inducible orphan G-protein-coupled receptors 1 and 4; class C family of seven-transmembrane G protein-coupled receptors, group 5, member A and D; Retinoic acid-inducible G-protein-coupled receptors (RAIGs), also referred to as GPCR class C group 5, are a group consisting of four orphan receptors RAIG1 (GPRC5A), RAIG2 (GPRC5B), RAIG3 (GPRC5C), and RAIG4 (GPRC5D). Unlike other members of the class C GPCRs which contain a large N-terminal extracellular domain, RAIGs have a shorter N-terminus. Thus, it is unlikely that RAIGs bind an agonist at its N-terminus domain. Instead, the agonists may bind to the seven-transmembrane domain of these receptors. In addition, RAIG2 and RAIG3 contain a cleavable signal peptide whereas RAIG1 and RAIG4 do not. Although their expression is induced by retinoic acid (vitamin A analog), their biological function is not clearly understood. To date, no ligand is known for the members of RAIG family. Three receptor types (RAIG1-3) are found in vertebrates, while RAIG4 is only present in mammals. They show distinct tissue distribution with RAIG1 being primarily expressed in the lung, RAIG2 in the brain and placenta, RAIG3 in the brain, kidney and liver, and RAIG4 in the skin. RAIG1 is evolutionarily conserved from mammals to fish. RAIG1 has been to shown to act as a tumor suppressor in non-small cell lung carcinoma as well as oral squamous cell carcinoma, but it could also act as an oncogene in breast cancer, colorectal cancer, and pancreatic cancer. Studies have shown that overexpression of RAIG1 decreases intracellular cAMP levels. Moreover, knocking out RAIG1 induces the activation of the NF-kB and STAT3 signaling pathways leading to cell proliferation and resistance to apoptosis. The specific function of RAIG4 is unknown; however, this protein may play a role in mediating the effects of retinoic acid on embryogenesis, differentiation, and tumorigenesis through interaction with a G-protein signaling cascade.

24-267 5.53e-22

7 transmembrane sweet-taste receptor of 3 GCPR; This is a domain of seven transmembrane regions that forms the C-terminus of some subclass 3 G-coupled-protein receptors. It is often associated with a downstream cysteine-rich linker domain, NCD3G pfam07562, which is the human sweet-taste receptor, and the N-terminal domain, ANF_receptor pfam01094. The seven TM regions assemble in such a way as to produce a docking pocket into which such molecules as cyclamate and lactisole have been found to bind and consequently confer the taste of sweetness.

30-267 5.18e-58

retinoic acid-inducible orphan G-protein-coupled receptor 2; class C family of seven-transmembrane G protein-coupled receptors, group 5, member B; Retinoic acid-inducible G-protein-coupled receptors (RAIGs), also referred to as GPCR class C group 5, are a group consisting of four orphan receptors RAIG1 (GPRC5A), RAIG2 (GPRC5B), RAIG3 (GPRC5C), and RAIG4 (GPRC5D). Unlike other members of the class C GPCRs which contain a large N-terminal extracellular domain, RAIGs have a shorter N-terminus. Thus, it is unlikely that RAIGs bind an agonist at its N-terminus domain. Instead, the agonists may bind to the seven-transmembrane domain of these receptors. In addition, RAIG2 and RAIG3 contain a cleavable signal peptide whereas RAIG1 and RAIG4 do not. Although their expression is induced by retinoic acid (vitamin A analog), their biological function is not clearly understood. To date, no ligand is known for the members of RAIG family. Three receptor types (RAIG1-3) are found in vertebrates, while RAIG4 is only present in mammals. They show distinct tissue distribution with RAIG1 being primarily expressed in the lung, RAIG2 in the brain and placenta, RAIG3 in the brain, kidney and liver, and RAIG4 in the skin. RAIG2 (GPRC5B), a mammalian Boss (Bride of sevenless) homolog, has been shown to activate obesity-associated inflammatory signaling in adipocytes, and that the GPRC5B knockout mice have been shown to be resistance to high-fat diet-induced obesity and insulin resistance.

48-271 1.30e-26

metabotropic glutamate receptor-like class C family of seven-transmembrane G protein-coupled receptors superfamily; The class C GPCRs consist of glutamate receptors (mGluR1-8), the extracellular calcium-sensing receptors (caSR), the gamma-amino-butyric acid type B receptors (GABA-B), the vomeronasal type-2 pheromone receptors (V2R), the type 1 taste receptors (TAS1R), and the promiscuous L-alpha-amino acid receptor (GPRC6A), as well as several orphan receptors. Structurally, these receptors are typically composed of a large extracellular domain containing a Venus flytrap module which possesses the orthosteric agonist-binding site, a cysteine-rich domain (CRD) with the exception of GABA-B receptors, and the seven-transmembrane domains responsible for G protein activation. Moreover, the Venus flytrap module shows high structural homology with bacterial periplasmic amino acid-binding proteins, which serve as primary receptors in transport of a variety of soluble substrates such as amino acids and polysaccharides, among many others. The class C GPCRs exist as either homo- or heterodimers, which are essential for their function. The GABA-B1 and GABA-B2 receptors form a heterodimer via interactions between the N-terminal Venus flytrap modules and the C-terminal coiled-coiled domains. On the other hand, heterodimeric CaSRs and Tas1Rs and homodimeric mGluRs utilize Venus flytrap interactions and intermolecular disulphide bonds between cysteine residues located in the cysteine-rich domain (CRD), which can also acts as a molecular link to mediate the signal between the Venus flytrap and the 7TMs. Furthermore, members of the class C GPCRs bind a variety of endogenous ligands, ranging from amino acids, ions, to pheromones and sugar molecules, and play important roles in many physiological processes such as synaptic transmission, calcium homeostasis, and the sensation of sweet and umami tastes.

24-267 5.53e-22

7 transmembrane sweet-taste receptor of 3 GCPR; This is a domain of seven transmembrane regions that forms the C-terminus of some subclass 3 G-coupled-protein receptors. It is often associated with a downstream cysteine-rich linker domain, NCD3G pfam07562, which is the human sweet-taste receptor, and the N-terminal domain, ANF_receptor pfam01094. The seven TM regions assemble in such a way as to produce a docking pocket into which such molecules as cyclamate and lactisole have been found to bind and consequently confer the taste of sweetness.

73-266 2.68e-05

Bride of sevenless, member of the class C family of seven-transmembrane G protein-coupled receptors; Bride of Sevenless (Boss) is a putative Drosophila melanogaster G protein-coupled receptor that functions as a glucose-responding receptor to regulate energy metabolism. Boss is expressed predominantly in the fly's fat body, a nutrient-sensing tissue functionally analogous to the mammalian liver and adipose tissues, and in photoreceptor cells. Boss, which is expressed on the surface of R8 photoreceptor cell, binds and activates the Sevenless receptor tyrosine kinase on the neighboring R7 precursor cell. Activation of Sevenless results in phosphorylation of the Sevenless, triggering a signaling transduction cascade through Ras pathway that ultimately leads to the differentiation of the R7 precursor into a fully functional R7 photoreceptor, the last of eight photoreceptors to differentiate in each ommatidium of the developing Drosophila eye. In the absence of either of Sevenless or Boss, the R7 precursor fails to differentiate as a photoreceptor and instead develops into a non-neuronal cone cell. Moreover, Boss mutants in Drosophila showed elevated food intake, but reduced stored triglyceride levels, suggesting that Boss may play a role in regulating energy homeostasis in nutrient sensing tissues. Furthermore, GPRC5B, a mammalian Boss homolog, activates obesity-associated inflammatory signaling in adipocytes, and that the GPRC5B knockout mice showed resistance to high-fat diet-induced obesity and insulin resistance.
