Anti-protein phosphatase targeting COQ7 antibodies are used for the immunodetection of the protein encoded by the PPTC7 gene. In humans, the canonical protein has a reported length of 304 amino acid residues and a mass of 32.6 kDa. Its subcellular localization is in the mitochondria. It is reported to be expressed in keratinocytes. A member of the PP2C protein family, it is reported to be a protein phosphatase, which positively regulates biosynthesis of the ubiquinone, coenzyme Q. Other names for this target antigen include protein phosphatase PTC7 homolog and PTC7 protein phosphatase homolog. Gene orthologs have been identified in the mouse, rat, bovine, frog, chimpanzee and chicken species.
