Summaries for NAT1 Gene

Entrez Gene Summary for NAT1 Gene

  • This gene is one of two arylamine N-acetyltransferase (NAT) genes in the human genome, and is orthologous to the mouse and rat Nat2 genes. The enzyme encoded by this gene catalyzes the transfer of an acetyl group from acetyl-CoA to various arylamine and hydrazine substrates. This enzyme helps metabolize drugs and other xenobiotics, and functions in folate catabolism. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Aug 2011]

GeneCards Summary for NAT1 Gene

NAT1 (N-Acetyltransferase 1) is a Protein Coding gene. Diseases associated with NAT1 include Ascending Cholangitis and Urinary Bladder Cancer. Among its related pathways are Metabolism and Drug metabolism - cytochrome P450. GO annotations related to this gene include acetyltransferase activity and arylamine N-acetyltransferase activity. An important paralog of this gene is NAT2.

UniProtKB/Swiss-Prot for NAT1 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.

Polymorphic Variants from UniProtKB/Swiss-Prot for NAT1 Gene

N-acetylation polymorphism is determined by a low or high NAT activity in liver and has been implicated in the action and toxicity of amine-containing drugs. Slow acetylation genotypes have been associated with significant lung cancer risk. Candidate risk factor for susceptibility to neural tube defects. The NAT1*10 allele has been associated with increased risk of colon and urinary bladder cancers and with higher levels of N-acetyltransferase activity and DNA adducts in aromatic amine tumor target organs such as colon and urinary bladder (PubMed:7585580).
