3-139 2.11e-07

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.

71-128 8.88e-03

melatonin receptor 1, member of the class A family of seven-transmembrane G protein-coupled receptors; Melatonin (N-acetyl-5-methoxytryptamine) is a naturally occurring sleep-promoting chemical found in vertebrates, invertebrates, bacteria, fungi, and plants. In mammals, melatonin is secreted by the pineal gland and is involved in regulation of circadian rhythms. Its production peaks during the nighttime, and is suppressed by light. Melatonin is shown to be synthesized in other organs and cells of many vertebrates, including the Harderian gland, leukocytes, skin, and the gastrointestinal (GI) tract, which contains several hundred times more melatonin than the pineal gland and is involved in the regulation of GI motility, inflammation, and sensation. Melatonin exerts its pleiotropic physiological effects through specific membrane receptors, named MT1A, MT1B, and MT1C, which belong to the class A rhodopsin-like G-protein coupled receptor family. MT1A and MT1B subtypes are present in mammals, whereas MT1C subtype has been found in amphibians and birds. The melatonin receptors couple to G proteins of the G(i/o) class, leading to the inhibition of adenylate cyclase.
