Anti-N-alpha-acetyltransferase 50, NatE catalytic subunit antibodies are used for the immunodetection of the protein encoded by the NAA50 gene. In humans, the canonical protein has a reported length of 169 amino acid residues and a mass of 19.4 kDa. Its subcellular localization is in the nucleus and cytoplasm. Alternative splicing is reported to yield 2 different isoforms for this protein. A member of the Acetyltransferase protein family, it is a reported N-alpha-acetyltransferase that acetylates the N-terminus of proteins that retain their initiating methionine. Other names for this target antigen include N-acetyltransferase 13 (GCN5-related), N-acetyltransferase 5, N-acetyltransferase san homolog, N-epsilon-acetyltransferase 50, natE catalytic subunit, and N-alpha-acetyltransferase 50. Gene orthologs have been identified in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species.
