olfactory receptor 11G2 [Rattus norvegicus]

Protein Classification

G-protein coupled receptor( domain architecture ID 11535993)

G-protein coupled receptor (GPCR), which belongs to the class A rhodopsin-like family of seven-transmembrane G protein-coupled receptors (7TM GPCRs), transmits physiological signals from the outside of the cell to the inside via G proteins by binding to an extracellular agonist, which induces conformational changes that lead to the activation of heterotrimeric G proteins, which then bind to and activate numerous downstream effector proteins; similar to Homo sapiens free acid receptor 4, orphan GPR22 and GPR52

rhodopsin receptor-like class A family of the seven-transmembrane G protein-coupled receptor ...
89-277 1.05e-06

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.

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.

107-284 1.85e-05

olfactory receptor family 56 and related proteins, member of the class A family of seven-transmembrane G protein-coupled receptors; This group includes human olfactory receptor family 56 and related proteins in other mammals, sauropsids, and fishes. Olfactory receptors (ORs) play a central role in olfaction, the sense of smell. ORs belong to the class A rhodopsin-like family of G protein-coupled receptors and constitute the largest multigene family in mammals of approximately 1,000 genes. More than 60% of human ORs are non-functional pseudogenes compared to only about 20% in mouse. Each OR can recognize structurally similar odorants, and a single odorant can be detected by several ORs. Binding of an odorant to the olfactory receptor induces a conformational change that leads to the activation of the olfactory-specific G protein (Golf). The G protein (Golf and/or Gs) in turn stimulates adenylate cyclase to make cAMP. The cAMP opens cyclic nucleotide-gated ion channels, which allow the influx of calcium and sodium ions, resulting in depolarization of the olfactory receptor neuron and triggering an action potential which transmits this information to the brain. A consensus nomenclature system based on evolutionary divergence is used here to classify the olfactory receptor family. The nomenclature begins with the root name OR, followed by an integer representing a family, a letter denoting a subfamily, and an integer representing the individual gene within the subfamily.

105-281 2.04e-05

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.

106-281 4.73e-05

amine receptors and similar proteins, member of the class A family of seven-transmembrane G protein-coupled receptors; Amine receptors of the class A family of GPCRs include adrenoceptors, 5-HT (serotonin) receptors, muscarinic cholinergic receptors, dopamine receptors, histamine receptors, and trace amine receptors. The receptors of amine subfamily are major therapeutic targets for the treatment of neurological disorders and psychiatric diseases. 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.

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.

106-284 1.08e-04

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.

108-284 2.58e-03

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.

106-275 3.37e-03

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.

107-281 4.98e-03

orphan G protein-coupled receptor 101, member of the class A family of seven-transmembrane G protein-coupled receptors; Gpr101, an orphan GPCR, is predominantly expressed in the brain within discrete nuclei and is predicted to couple to the stimulatory G(s) protein, a potent activator of adenylate cyclase. GPR101 has been implicated in mediating the actions of GnRH-(1-5), a pentapeptide formed by metallopeptidase cleavage of the decapeptide gonadotropin-releasing hormone (GnRH), which plays a critical role in the regulation of the hypothalamic-pituitary-gonadal axis. GnRH-(1-5) acts on GPR101 to stimulate epidermal growth factor (EFG) release and EFG-receptor (EGFR) phosphorylation, leading to enhanced cell migration and invasion in the Ishikawa endometrial cancer cell line. Furthermore, these effects of GnRH-(1-5) are also dependent on enzymatic activation of matrix metallopeptidase-9 (MMP-9). GPR101 is a member of the class A family of GPCRs, which includes receptors for hormones, neurotransmitters, sensory stimuli, 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.

98-284 5.01e-03

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.

allatostatin-A receptor in insects, member of the class A family of seven-transmembrane G protein-coupled receptors; The G protein-coupled AstA receptor 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.

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.
