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).

Summaries for HTR2A Gene

Entrez Gene Summary for HTR2A Gene

  • 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]

GeneCards Summary for HTR2A Gene

HTR2A (5-Hydroxytryptamine Receptor 2A) is a Protein Coding gene. Diseases associated with HTR2A include Major Depressive Disorder and Obsessive-Compulsive Disorder. Among its related pathways are GPCRs, Other and Development Endothelin-1/EDNRA signaling. Gene Ontology (GO) annotations related to this gene include G protein-coupled receptor activity and drug binding. An important paralog of this gene is HTR2C.

UniProtKB/Swiss-Prot Summary for HTR2A Gene

  • G-protein coupled receptor for 5-hydroxytryptamine (serotonin) (PubMed:1330647, PubMed:18703043, PubMed:19057895). 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) (PubMed:28129538). Ligand binding causes a conformation change that triggers signaling via guanine nucleotide-binding proteins (G proteins) and modulates the activity of down-stream effectors (PubMed:28129538). Beta-arrestin family members inhibit signaling via G proteins and mediate activation of alternative signaling pathways (PubMed:28129538). 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 (PubMed:18703043, PubMed:28129538). Affects neural activity, perception, cognition and mood (PubMed:18297054). 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.
  • (Microbial infection) Acts as a receptor for human JC polyomavirus/JCPyV.

Tocris Summary for HTR2A Gene

  • Serotonin 5-HT2A receptors, previously known as 5-HT2 receptors, are located primarily in the neocortex, caudate nucleus, nucleus accumbens, hippocampus, and vascular and non-vascular smooth muscle cells. 5-HT2A receptors play a role in the control of appetite.
