Catalyzes the transfer of a methyl group onto N-acetylserotonin, producing melatonin (N-acetyl-5-methoxytryptamine).

By similarity

Miscellaneous

Pineal melatonin synthesis is severely compromised in most inbred strains. In many inbred strains, genetic defects in ASMT have been identified. Melatonin production may have an impact on gonadal development, testis development being significantly promoted in melatonin-deficient C57BL/6J x Mus musculus molossinus animals (PubMed:20308563).1 Publication
