Anti-INPP5K antibodies are used in the immunodetection of the protein inositol polyphosphate-5-phosphatase K. In humans, the canonical protein has a reported length of 448 amino acid residues and a mass of 51.1 kDa. Its subcellular localization is in the ER and cytoplasm. Up to 2 different isoforms have been reported for this protein. It is widely expressed across many tissue types. A member of the Inositol 1,4,5-trisphosphate 5-phosphatase type II protein family, INPP5K is reported to be an inositol 5-phosphatase, which acts on inositol 1,4,5-trisphosphate, inositol 1,3,4,5-tetrakisphosphate, phosphatidylinositol 4,5-bisphosphate and phosphatidylinositol 3,4,5-trisphosphate. Synonyms for this target antigen include PPS, SKIP, phosphatidylinositol-3,4,5-trisphosphate 5-phosphatase, phosphatidylinositol-4,5-bisphosphate 5-phosphatase, skeletal muscle and kidney-enriched inositol phosphatase, and MDCCAID. A number of INPP5K antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
