Anti-TRMT9B antibodies are used in the immunodetection of the protein tRNA methyltransferase 9B (putative). In humans, the canonical protein has a reported length of 454 amino acid residues and a mass of 51.3 kDa. Up to 2 different isoforms have been reported for this protein. It is notably widely expressed in many tissue types. A member of the Methyltransferase protein superfamily, TRMT9B is believed to modifie wobble uridines in specific arginine and glutamic acid tRNAs. Synonyms for this target antigen include probable tRNA methyltransferase 9B and probable tRNA methyltransferase 9-like protein. TRMT9B gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Some TRMT9B antibodies may have been used in research and have associated citations. Immunofluorescence is a widely used application for these antibodies. Western Blot, Immunocytochemistry, and Immunohistochemistry are also common applications.
