seven-transmembrane G protein-coupled receptor superfamily; This hierarchical evolutionary ...
42-101 2.01e-18

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.

42-94 9.11e-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.

43-96 3.23e-03

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).

42-94 6.60e-03

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.

45-94 7.77e-03

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.

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.
