UniProt Protein Function: | 5-HT(2A): This is one of the several different receptors for 5- hydroxytryptamine (serotonin), a biogenic hormone that functions as a neurotransmitter, a hormone, and a mitogen. This receptor mediates its action by association with G proteins that activate a phosphatidylinositol-calcium second messenger system. This receptor is involved in tracheal smooth muscle contraction, bronchoconstriction, and control of aldosterone production. Belongs to the G-protein coupled receptor 1 family. Protein type: Membrane protein, integral; GPCR, family 1; Receptor, GPCR; Membrane protein, multi-pass Chromosomal Location of Human Ortholog: 13q14-q21 Cellular Component: cell soma; axon; integral to plasma membrane; cytoplasmic membrane-bound vesicle; plasma membrane; dendritic shaft; caveola; cytosol Molecular Function: serotonin binding; serotonin receptor activity; protein complex binding; G-protein alpha-subunit binding; drug binding Biological Process: cell death; urinary bladder smooth muscle contraction; phosphoinositide 3-kinase cascade; negative regulation of potassium ion transport; thermoregulation; regulation of dopamine secretion; positive regulation of MAP kinase activity; synaptic transmission; behavioral response to cocaine; positive regulation of cell proliferation; detection of temperature stimulus involved in sensory perception of pain; artery smooth muscle contraction; serotonin receptor signaling pathway; regulation of behavior; aging; response to drug; serotonin receptor, phospholipase C activating pathway; regulation of hormone secretion; negative regulation of synaptic transmission, glutamatergic; positive regulation of phosphatidylinositol biosynthetic process; sleep; memory; cellular calcium ion homeostasis; detection of mechanical stimulus involved in sensory perception of pain; positive regulation of peptidyl-tyrosine phosphorylation; phospholipase C activation; release of sequestered calcium ion into cytosol; positive regulation of glycolysis; positive regulation of vasoconstriction; positive regulation of fat cell differentiation Disease: Schizophrenia; Alcohol Dependence; Anorexia Nervosa, Susceptibility To, 1; Obsessive-compulsive Disorder; Major Depressive Disorder |

NCBI Summary: | This gene encodes one of the receptors for serotonin, a neurotransmitter with many roles. Mutations in this gene are associated with susceptibility to schizophrenia and obsessive-compulsive disorder, and are also associated with response to the antidepressant citalopram in patients with major depressive disorder (MDD). MDD patients who also have a mutation in intron 2 of this gene show a significantly reduced response to citalopram as this antidepressant downregulates expression of this gene. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Sep 2009] |
