Anti-NTMT2 antibodies are used in the immunodetection of the protein N-terminal Xaa-Pro-Lys N-methyltransferase 2. In humans, the canonical protein has a reported length of 283 amino acid residues and a mass of 32.4 kDa. Its subcellular localization is in the nucleus. A member of the NTM1 protein family, NTMT2 is reported to be an alpha N-methyltransferase that methylates the N-terminus of target proteins containing the N-terminal motif [Ala/Pro/Ser]-Pro-Lys when the initiator Met is cleaved. Synonyms for this target antigen include alpha N-terminal protein methyltransferase 1B, methyltransferase like 11B, methyltransferase-like protein 11B, and X-Pro-Lys N-terminal protein methyltransferase 1B. NTMT2 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species.
