Anti-PWP2 antibodies are used in the immunodetection of the protein PWP2 small subunit processome component. In humans, the canonical protein has a reported length of 919 amino acid residues and a mass of 102.5 kDa. Its subcellular localization is in the nucleus. A member of the WD repeat PWP2 protein family, PWP2 is known to be a part of the small subunit (SSU) processome, first precursor of the small eukaryotic ribosomal subunit. Synonyms for this target antigen include PWP2H, UTP1, periodic tryptophan protein 2 homolog, PWP2 periodic tryptophan protein homolog, PWP2, UTPB SSU processome subunit, and EHOC-17. PWP2 gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. Some PWP2 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.
