Gene Gene information from NCBI Gene database.
Entrez ID 1312
Gene name Catechol-O-methyltransferase
Gene symbol COMT
Synonyms (NCBI Gene)
HEL-S-98n
Chromosome 22
Chromosome location 22q11.21
Summary 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 pathwa

Protein name Catechol O-methyltransferase (EC 2.1.1.6)
Protein function 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. {ECO:000
