Anti-RPP38 antibodies are used in the immunodetection of the protein ribonuclease P/MRP subunit p38. In humans, the canonical protein has a reported length of 283 amino acid residues and a mass of 31.8 kDa. Its subcellular localization is in the nucleus. It is notably expressed in many tissues, such as the bronchus, tonsil, and breast. A member of the Eukaryotic ribosomal protein eL8 protein family, RPP38 is known to be a component of ribonuclease P, a ribonucleoprotein complex that generates mature tRNA molecules by cleaving their 5'-ends. Synonyms for this target antigen include RNaseP protein p38, ribonuclease P/MRP 38kDa subunit, and ribonuclease P protein subunit p38. RPP38 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Some RPP38 antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. In addition, ELISA is also a common application.
