Anti-methyltransferase 22, Kin17 lysine antibodies are used for the immunodetection of the protein encoded by the METTL22 gene. In humans, the canonical protein has a reported length of 404 amino acid residues and a mass of 44.5 kDa. Its subcellular localization is in the nucleus. Alternative splicing is reported to yield 3 different isoforms for this protein. It is a member of the METTL22 protein family. Other names for this target antigen include LP8272, methyltransferase like 22, and methyltransferase-like protein 22. Gene orthologs have been identified in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species.
