Summaries for COMT Gene

Entrez Gene Summary for COMT Gene

  • Catechol-O-methyltransferase catalyzes the transfer of a methyl group from S-adenosylmethionine to catecholamines, including the neurotransmitters dopamine, epinephrine, and norepinephrine. This O-methylation results in one of the major degradative pathways of the catecholamine transmitters. In addition to its role in the metabolism of endogenous substances, COMT is important in the metabolism of catechol drugs used in the treatment of hypertension, asthma, and Parkinson disease. COMT is found in two forms in tissues, a soluble form (S-COMT) and a membrane-bound form (MB-COMT). The differences between S-COMT and MB-COMT reside within the N-termini. Several transcript variants are formed through the use of alternative translation initiation sites and promoters. [provided by RefSeq, Sep 2008]

GeneCards Summary for COMT Gene

COMT (Catechol-O-Methyltransferase) is a Protein Coding gene. Diseases associated with COMT include panic disorder and cisplatin toxicity. Among its related pathways are Metabolism and Metabolism. GO annotations related to this gene include magnesium ion binding and catechol O-methyltransferase activity. An important paralog of this gene is LRTOMT.

UniProtKB/Swiss-Prot for COMT Gene

  • Catalyzes the O-methylation, and thereby the inactivation, of catecholamine neurotransmitters and catechol hormones. Also shortens the biological half-lives of certain neuroactive drugs, like L-DOPA, alpha-methyl DOPA and isoproterenol

Tocris Summary for COMT Gene

  • Catechol-O-methyltransferase (COMT) is involved in metabolism of catecholamines (dopamine, adrenalin and noradrenalin). COMT is localized to postsynaptic neurons where it degrades neurotransmitters following their release.
