|Function||G-protein coupled receptor for 5-hydroxytryptamine (serotonin). Also functions as a receptor for various drugs and psychoactive substances, including mescaline, psilocybin, 1-(2,5- dimethoxy-4-iodophenyl)-2-aminopropane (DOI) and lysergic acid diethylamide (LSD). Ligand binding causes a conformation change that triggers signaling via guanine nucleotide-binding proteins (G proteins) and modulates the activity of down-stream effectors. Beta-arrestin family members inhibit signaling via G proteins and mediate activation of alternative signaling pathways. Signaling activates phospholipase C and a phosphatidylinositol-calcium second messenger system that modulates the activity of phosphatidylinositol 3-kinase and promotes the release of Ca(2+) ions from intracellular stores. Affects neural activity, perception, cognition and mood. Plays a role in the regulation of behavior, including responses to anxiogenic situations and psychoactive substances. Plays a role in intestinal smooth muscle contraction, and may play a role in arterial vasoconstriction.|

This gene encodes one of the receptors for serotonin, aneurotransmitter with many roles. Mutations in this gene areassociated with susceptibility to schizophrenia andobsessive-compulsive disorder, and are also associated withresponse to the antidepressant citalopram in patients with majordepressive disorder (MDD). MDD patients who also have a mutation inintron 2 of this gene show a significantly reduced response tocitalopram as this antidepressant downregulates expression of thisgene. Multiple transcript variants encoding different isoforms havebeen found for this gene.
