Anti-N-alpha-acetyltransferase 11, NatA catalytic subunit antibodies are used for the immunodetection of the protein encoded by the NAA11 gene. In humans, the canonical protein has a reported length of 229 amino acid residues and a mass of 26 kDa. Its subcellular localization is in the nucleus and cytoplasm. It is a member of the Acetyltransferase protein family. Other names for this target antigen include ARD1 homolog B, N-terminal acetyltransferase complex ARD1 subunit homolog B, human arrest defective 2, natA catalytic subunit Naa11, and N-alpha-acetyltransferase 11. Gene orthologs have been identified in the mouse, rat, bovine and chimpanzee species.
