Protein Name: Catechol O-methyltransferase

UniprotKB/SwissProt ID: COMT_MOUSE (O88587)

Gene Name: Comt

Synonyms: Comt1

Organism: Mus musculus (Mouse).

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: Isoform Soluble: Cytoplasm. Isoform Membrane-bound: Cell membrane; Single-pass type II membrane protein; Extracellular side.
