Anti-MTG2 antibodies are used in the immunodetection of the protein mitochondrial ribosome associated GTPase 2. In humans, the canonical protein has a reported length of 406 amino acid residues and a mass of 44 kDa. Its subcellular localization is in the mitochondria. Up to 2 different isoforms have been reported for this protein. It is notably expressed in many tissues, such as the cerebellum and cerebral cortex. A member of the OBG GTPase protein family, MTG2 is reported to play a role in the regulation of the mitochondrial ribosome assembly and of translational activity. Synonyms for this target antigen include ObgH1, dJ1005F21.2, GTP binding protein 5 (putative), GTP-binding protein 5, protein obg homolog 1, and GTPBP5. MTG2 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Some MTG2 antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
