Anti-PPP4C antibodies are used in the immunodetection of the protein protein phosphatase 4 catalytic subunit. In humans, the canonical protein has a reported length of 307 amino acid residues and a mass of 35.1 kDa. Its subcellular localization is in the nucleus and cytoplasm. It is notably widely expressed in many tissue types. A member of the PPP phosphatase protein family, PPP4C is reported to be a protein phosphatase that is involved in many processes such as microtubule organization at centrosomes, maturation of spliceosomal snRNPs, apoptosis, DNA repair, tumor necrosis factor (TNF)-alpha signaling, activation of c-Jun N-terminal kinase MAPK8, regulation of histone acetylation, DNA damage checkpoint signaling, NF-kappa-B activation and cell migration. Synonyms for this target antigen include PP4, PP4C, PPH3, PPP4, PPX, and PP-X. PPP4C gene orthologs have been reported in the mouse, rat, bovine, frog and chimpanzee species. A number of PPP4C antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. Immunofluorescence and Immunohistochemistry are also common applications.
