Anti-methyltransferase 14, N6-adenosine-methyltransferase subunit antibodies are used for the immunodetection of the protein encoded by the METTL14 gene. In humans, the canonical protein has a reported length of 456 amino acid residues and a mass of 52.2 kDa. Its subcellular localization is in the nucleus. A member of the MT-A70-like protein family, it is known to be involved with forebrain radial glial cell differentiation and RNA splicing. Other names for this target antigen include N6-adenosine-methyltransferase subunit METTL14, methyltransferase like 14, methyltransferase-like protein 14, and N6-adenosine-methyltransferase non-catalytic subunit. Gene orthologs have been identified in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species.
