Summaries for NNMT Gene

Entrez Gene Summary for NNMT Gene

  • N-methylation is one method by which drug and other xenobiotic compounds are metabolized by the liver. This gene encodes the protein responsible for this enzymatic activity which uses S-adenosyl methionine as the methyl donor. [provided by RefSeq, Jul 2008]

GeneCards Summary for NNMT Gene

NNMT (Nicotinamide N-Methyltransferase) is a Protein Coding gene. Diseases associated with NNMT include Kidney Cancer and Parkinson Disease, Late-Onset. Among its related pathways are Cytochrome P450 - arranged by substrate type and Viral mRNA Translation. Gene Ontology (GO) annotations related to this gene include methyltransferase activity and nicotinamide N-methyltransferase activity. An important paralog of this gene is INMT.

UniProtKB/Swiss-Prot for NNMT Gene

  • Catalyzes the N-methylation of nicotinamide and other pyridines to form pyridinium ions. This activity is important for biotransformation of many drugs and xenobiotic compounds.
