General description

5-hydroxytryptamine receptor 2A (UniProt P28223; also known as 5-HT-2, 5-HT-2A, 5-HT2A, Serotonin receptor 2A) is encoded by the HTR2A (also known as HTR2) gene (Gene ID 3356) in human. Hydroxytryptamine (5-HT) is synthesized in enterochromaffin cells in the intestine and in serotonergic nerve terminals. In the periphery, 5-HT mediates gastrointestinal motility, platelet aggregation, and contraction of blood vessels. Many functions of the central nervous system are influenced by 5-HT, including sleep, motor activity, sensory perception, arousal and appetite. A family of 12 GPCRs and one ion channel mediate the biological effects of 5-HT. 5-HT2A receptor, which couples to Gq/11 to increase intracellular calcium, is widely expressed at central and peripheral sites of 5-HT action and contributes to many of the physiological effects of 5-HT. The hallucinogenic activity of LSD is mediated in part by its action as a partial to full agonist of 5-HT2A receptor, and the activity of atypical antipsychotics such as clozapine appears to be mediated in part by antagonism against 5-HT2A receptor. Human 5-HT2A receptor contains four extracellular domains (a.a. 1-75, 133-148, 216-233, 347-362), seven transmembrane segments (a.a. 76-99, 111-132, 149-171, 192-215, 234-254, 325-346, 363-384), and four cytoplasmic domains (a.a. 100-110, 172-191, 255-324, 385-471).
