Anti-MTERF3 antibodies are used in the immunodetection of the protein mitochondrial transcription termination factor 3. In humans, the canonical protein has a reported length of 417 amino acid residues and a mass of 48 kDa. Its subcellular localization is in the mitochondria. Up to 3 different isoforms have been reported for this protein. It is reported to be highly expressed in the heart, liver, kidney and testis. A member of the MTERF protein family, MTERF3 is known to bind promoter DNA and regulates initiation of transcription. Synonyms for this target antigen include MTERFD1, transcription termination factor 3, mitochondrial, MTERF domain containing 1, mTERF domain-containing protein 1, mitochondrial, and CGI-12. MTERF3 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Some MTERF3 antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. ELISA, Immunocytochemistry, Immunofluorescence, and Immunohistochemistry are also common applications.
