Anti-PLPP4 antibodies are used in the immunodetection of the protein phospholipid phosphatase 4. In humans, the canonical protein has a reported length of 271 amino acid residues and a mass of 30.4 kDa. Its subcellular localization is in the membrane. Up to 4 different isoforms have been reported for this protein. It is noted to be expressed mainly to the brain, kidney and testis, and to a lesser extent the bone marrow, thymus, prostate, liver and uterus. A member of the PA-phosphatase related phosphoesterase protein family, PLPP4 is known to be involved with the metabolism of lipids. Synonyms for this target antigen include diacylglycerol pyrophosphate phosphatase-like 2, phosphatidate phosphatase PPAPDC1A, phosphatidic acid phosphatase type 2 domain containing 1A, and diacylglycerol pyrophosphate like 2. PLPP4 gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. Some PLPP4 antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. ELISA, Immunocytochemistry, Immunofluorescence, and Immunohistochemistry are also common applications.
