Anti-NAT11 antibodies enable researchers to detect and measure the NAT11 antigen in biological samples. This target is a reported synonym of the NAA40 gene, which encodes N-alpha-acetyltransferase 40, NatD catalytic subunit. This protein is known to function in the metabolism of lipids, among other biological roles. The human version of NAT11 has a canonical amino acid length of 237 residues and a protein mass of 27.2 kilodaltons, although 3 isoforms have been identified. It is reported to be localized in the nucleus and cytoplasm of cells. NAT11 is a member of the Acetyltransferase protein family.
