Anti-PET117 antibodies are used in the immunodetection of the protein PET117 cytochrome c oxidase chaperone. In humans, the canonical protein has a reported length of 81 amino acid residues and a mass of 9.2 kDa. Its subcellular localization is in the mitochondria. It is notably expressed in many tissues, such as the caudate, urinary bladder, and appendix. It is a member of the PET117 protein family. The PET117 gene has been associated with the disease, Mitochondrial complex IV deficiency. Synonyms for this target antigen include PET117 homolog, alternative protein CSRP2BP, and protein PET117 homolog, mitochondrial. PET117 gene orthologs have been reported in the mouse, bovine, zebrafish, chimpanzee and chicken species. Some Pet117 antibodies may have been used in research and have associated citations. These antibodies are most commonly used in Immunohistochemistry experiments, among other applications.
