NAT1（N-acetyltransferase 1），癌症关联基因，基因ID：9，该基因是人类基因组中两个芳胺N-乙酰转移酶（NAT）基因之一，与小鼠和大鼠NAT2基因同源。该基因编码的酶催化乙酰基从乙酰辅酶A转移到各种芳胺和肼底物。这种酶有助于药物和其他外源性物质的代谢，并在叶酸分解代谢中发挥作用。已发现该基因编码不同亚型的多个转录变体。[由RefSeq提供，2011年8月]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.
