Anti-NAT10 antibodies are used in the immunodetection of the protein N-acetyltransferase 10. In humans, the canonical protein has a reported length of 1025 amino acid residues and a mass of 115.7 kDa. Its subcellular localization is in the nucleus. Alternative splicing is reported to yield 2 different isoforms for this protein. The NAT10 protein is a member of the RNA cytidine acetyltransferase protein family. Post-translational modifications have been described, including acetylation. Synonyms for this target antigen include Kre33, NET43, RNA cytidine acetyltransferase, 18S rRNA cytosine acetyltransferase, N-acetyltransferase 10 (GCN5-related), and ALP.
