Anti-PLSCR4 antibodies are used in the immunodetection of the protein phospholipid scramblase 4. In humans, the canonical protein has a reported length of 329 amino acid residues and a mass of 37 kDa. Its subcellular localization is in the membrane. Up to 2 different isoforms have been reported for this protein. It is found to be expressed in the heart, brain, placenta, lung, liver, kidney, pancreas, spleen, thymus, prostate, testis, uterus, small intestine and colon. A member of the Phospholipid scramblase protein family, PLSCR4 is believed to mediate accelerated ATP-independent bidirectional transbilayer migration of phospholipids upon binding calcium ions that results in a loss of phospholipid asymmetry in the plasma membrane. Synonyms for this target antigen include PL scramblase 4, cell growth inhibiting protein 43, and Ca(2+)-dependent phospholipid scramblase 4. PLSCR4 gene orthologs have been reported in the mouse, rat, bovine and chimpanzee species. Some PLSCR4 antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
