Chromosome mapping of the genes for murine arylamine N-acetyltransferases (NATs), enzymes involved in the metabolism of carcinogens: identification of a novel upstream noncoding exon for murine Nat2.


Arylamine N-acetyltransferases (NATs) catalyse acetylation reactions which can result in either detoxification or activation of arylamine carcinogens. The human NAT loci (NAT1, NAT2, and a pseudogene, NATP) have been mapped to human chromosome 8p22, a region frequently deleted in tumours. There are three functional genes in mice (Nat1, Nat2, and Nat3… (More)
