Anti-methyltransferase 8, methylcytidine antibodies are used for the immunodetection of the protein encoded by the METTL8 gene. In humans, the canonical protein has a reported length of 291 amino acid residues and a mass of 33.4 kDa. Its subcellular localization is in the mitochondria. Alternative splicing is reported to yield 2 different isoforms for this protein. It is a member of the METL protein family. Other names for this target antigen include mRNA N(3)-methylcytidine methyltransferase METTL8, methyltransferase like 8, methyltransferase-like protein 8, and tRNA N(3)-methylcytidine methyltransferase METTL8, mitochondrial. Gene orthologs have been identified in the mouse, rat, bovine, zebrafish, chimpanzee and chicken species.
