Anti-PRORP antibodies are used in the immunodetection of the protein protein only RNase P catalytic subunit. In humans, the canonical protein has a reported length of 583 amino acid residues and a mass of 67.3 kDa. Its subcellular localization is in the mitochondria. Up to 4 different isoforms have been reported for this protein. It is notably widely expressed in many tissue types. It is a member of the PPR protein family. The PRORP gene has been associated with the disease, Combined oxidative phosphorylation deficiency. Synonyms for this target antigen include KIAA0391, MRPP3, mitochondrial ribonuclease P catalytic subunit, mitochondrial RNase P protein 3, mitochondrial RNase P subunit 3, and COXPD54. PRORP gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Some PRORP antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. Immunofluorescence and Immunohistochemistry are also common applications.
