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:0000269|PubMed:22775292}. |
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:0000269|PubMed:22775292, ECO:0000269|PubMed:7989373, ECO:0000269|PubMed:8574683}. |
