CC -!- FUNCTION: Catalyzes the O-methylation, and thereby the inactivation, of
CC catecholamine neurotransmitters and catechol hormones.
CC {ECO:0000250|UniProtKB:P21964}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=a catechol + S-adenosyl-L-methionine = a guaiacol + H(+) + S-
CC adenosyl-L-homocysteine; Xref=Rhea:RHEA:17877, ChEBI:CHEBI:15378,
CC ChEBI:CHEBI:33566, ChEBI:CHEBI:57856, ChEBI:CHEBI:59789,
CC ChEBI:CHEBI:134251; EC=2.1.1.6;
CC Evidence={ECO:0000250|UniProtKB:P21964};
CC -!- COFACTOR:
CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC Evidence={ECO:0000255|PIRSR:PIRSR037177-3};
CC Note=Binds 1 Mg(2+) ion per subunit. {ECO:0000255|PIRSR:PIRSR037177-3};
CC -!- SUBCELLULAR LOCATION: Secreted {ECO:0000305}.
CC -!- TISSUE SPECIFICITY: Strongly expressed in eye, diencephalon, spinal
CC cord, hindbrain, liver, kidney and telencephalon. Also detected at very
CC low levels in muscle, spleen, anterior gut and heart. In eye, expressed
CC strongly in retina. In brain, expressed in the central part of the
CC telencephalon, the periventricular gray zone of the optic tectum, the
CC periglomerular nucleus, the olfactory bulb, and the region adjacent to
CC the diencephalic ventricle in the hypothalamus. Expressed in gill, with
CC strongest expression in gill filaments nearest the gill arch, and in
CC esophageal epithelium. {ECO:0000269|PubMed:28844929}.
CC -!- SIMILARITY: Belongs to the class I-like SAM-binding methyltransferase
CC superfamily. Cation-dependent O-methyltransferase family.
CC {ECO:0000255|PROSITE-ProRule:PRU01019}.
