Summaries for NAT2 Gene

Entrez Gene Summary for NAT2 Gene

  • This gene encodes an enzyme that functions to both activate and deactivate arylamine and hydrazine drugs and carcinogens. Polymorphisms in this gene are responsible for the N-acetylation polymorphism in which human populations segregate into rapid, intermediate, and slow acetylator phenotypes. Polymorphisms in this gene are also associated with higher incidences of cancer and drug toxicity. A second arylamine N-acetyltransferase gene (NAT1) is located near this gene (NAT2). [provided by RefSeq, Jul 2008]

GeneCards Summary for NAT2 Gene

NAT2 (N-Acetyltransferase 2) is a Protein Coding gene. Diseases associated with NAT2 include Nat2-Related Altered Drug Metabolism and Isoniazid Toxicity. Among its related pathways are Metabolism and Caffeine Pathway, Pharmacokinetics. GO annotations related to this gene include acetyltransferase activity and arylamine N-acetyltransferase activity. An important paralog of this gene is NAT1.

UniProtKB/Swiss-Prot for NAT2 Gene

  • Participates in the detoxification of a plethora of hydrazine and arylamine drugs. Catalyzes the N- or O-acetylation of various arylamine and heterocyclic amine substrates and is able to bioactivate several known carcinogens.
