37-354 5.38e-115

Serpentine type 7TM GPCR chemoreceptor Srw; Chemoreception is mediated in Caenorhabditis elegans by members of the seven-transmembrane G-protein-coupled receptor class (7TM GPCRs) of proteins which are of the serpentine type. Srw is a solo family amongst the superfamilies of chemoreceptors. Chemoperception is one of the central senses of soil nematodes like C. elegans which are otherwise 'blind' and 'deaf'. The genes encoding Srw do not appear to be under as strong an adaptive evolutionary pressure as those of Srz.

45-346 6.17e-31

FMRFamide (Phe-Met-Arg-Phe) receptors and related proteins, member of the class A family of seven-transmembrane G protein-coupled receptors; This group includes Drosophila melanogaster G-protein coupled FMRFamide (Phe-Met-Arg-Phe-NH2) receptor DrmFMRFa-R and related invertebrate receptors, as well as the vertebrate proteins GPR139 and GPR142. DrmFMRFa-R binds with high affinity to FMRFamide and intrinsic FMRFamide-related peptides. FMRFamide is a neuropeptide from the family of FMRFamide-related peptides (FaRPs), which all containing a C-terminal RFamide (Arg-Phe-NH2) motif and have diverse functions in the central and peripheral nervous systems. FMRFamide is an important neuropeptide in many types of invertebrates such as insects, nematodes, molluscs, and worms. In invertebrates, the FMRFamide-related peptides are involved in the regulation of heart rate, blood pressure, gut motility, feeding behavior, and reproduction. On the other hand, in vertebrates such as mice, they play a role in the modulation of morphine-induced antinociception. Orphan receptors GPR139 and GPR142 are very closely related G protein-coupled receptors, but they have different expression patterns in the brain and in other tissues. These receptors couple to inhibitory G proteins and activate phospholipase C. Studies suggested that dimer formation may be required for their proper function. GPR142 is predominantly expressed in pancreatic beta-cells and mediates enhancement of glucose-stimulated insulin secretion, whereas GPR139 is mostly expressed in the brain and is suggested to play a role in the control of locomotor activity. Tryptophan and phenylalanine have been identified as putative endogenous ligands of GPR139.

45-325 9.04e-04

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.

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.
