Protein Name: Catechol O-methyltransferase

UniprotKB/SwissProt ID: P21964 (P21964)

Gene Name: COMT

Organism: Homo sapiens (Human)

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

Other Modifications: View all modification sites in dbPTM

Protein Subcellular Localization: Cytoplasm. Cell membrane
