N-methylation of endogenous and xenobiotic compounds is a major method by which they are degraded. This gene encodes an enzyme that N-methylates indoles such as tryptamine. Alternative splicing results in multiple transcript variants. Read-through transcription also exists between this gene and the downstream FAM188B (family with sequence similarity 188, member B) gene.,INMT,TEMT,Signal Transduction,Endocrine & Metabolism,Amino acid metabolism,Drug metabolism,TEMT
