Anti-NAA20 antibodies are used in the immunodetection of the protein N-alpha-acetyltransferase 20, NatB catalytic subunit. In humans, the canonical protein has a reported length of 178 amino acid residues and a mass of 20.4 kDa. Its subcellular localization is in the nucleus and cytoplasm. Up to 2 different isoforms have been reported for this protein. A member of the Acetyltransferase protein family, NAA20 is a known catalytic subunit of the NatB complex which catalyzes acetylation of the N-terminal methionine residues of peptides beginning with Met-Asp, Met-Glu, Met-Asn and Met-Gln. Synonyms for this target antigen include NAT3, NAT3P, NAT5, NAT5P, dJ1002M8.1, N-alpha-acetyltransferase 20, N-acetyltransferase 3 homolog, and MRT73. NAA20 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Some NAA20 antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. ELISA, Immunofluorescence, and Immunohistochemistry are also common applications.
