InnateDB Gene

IDBG-40457 (ASMT)

Protein Structure

UniProt Annotation

Function

Isoform 1 catalyzes the transfer of a methyl group onto N-acetylserotonin, producing melatonin (N-acetyl-5- methoxytryptamine). Isoform 2 and isoform 3 lack enzyme activity. {ECO:0000269PubMed:22775292}.

Subcellular Localization

Disease Associations

Tissue Specificity

Expressed in the pineal gland (at protein level). In the retina, very low expression is found at the mRNA level (PubMed:7989373), and not at the protein level (PubMed:8574683). {ECO:0000269PubMed:22775292, ECO:0000269PubMed:7989373, ECO:0000269PubMed:8574683}.
