Protein Structure

UniProt Annotation

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.

Subcellular Localization

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