Anti-AAC1 antibodies enable researchers to detect and measure the AAC1 antigen in biological samples. This target is a reported synonym of the NAT1 gene, which encodes N-acetyltransferase 1. This protein is known to function in metabolic processes, among other biological roles. The human version of AAC1 has a canonical amino acid length of 290 residues and a protein mass of 33.9 kilodaltons. It is reported to be localized in the cytoplasm of cells and notably expressed in many tissues, such as the bronchus, urinary bladder, and adrenal gland. AAC1 is a member of the Arylamine N-acetyltransferase protein family.
