Anti-PIP4P1 antibodies are used in the immunodetection of the protein phosphatidylinositol-4,5-bisphosphate 4-phosphatase 1. In humans, the canonical protein has a reported length of 277 amino acid residues and a mass of 29.5 kDa. Its subcellular localization is in the cytoplasmic vesicles, lysosomes, and cell membrane. Up to 3 different isoforms have been reported for this protein. It is ubiquitously expressed across many tissue types. PIP4P1 is known to catalyze the hydrolysis of phosphatidylinositol-4,5-bisphosphate (PtdIns-4,5-P2) to phosphatidylinositol-4-phosphate (PtdIns-4-P). Synonyms for this target antigen include ptdIns-4,5-P(2) 4-phosphatase type I, ptdIns-4,5-P2 4-Ptase I, transmembrane protein 55B, type 1 PtdIns-4,5-P2 4-Ptase, and type 1 phosphatidylinositol 4,5-bisphosphate 4-phosphatase. PIP4P1 gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. Some PIP4P1 antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. ELISA, Flow Cytometry, and Immunohistochemistry are also common applications.
