The following inositol polyphosphate-5-phosphatase F ELISA kits are useful research tools for the measurement of inositol polyphosphate-5-phosphatase F in biological samples. In humans this protein is encoded by the INPP5F gene. This protein is reported to be an inositol 4-phosphatase, which mainly acts on phosphatidylinositol 4-phosphate. The canonical protein structure is reported to have an amino acid sequence of 1132 residues and a mass of 128.4 kDa. Its subcellular location is known to be in the endosome. In addition, it is ubiquitously expressed across many tissue types. As many as 4 protein isoforms have been reported. This protein may also be known as MSTPO47, SAC2, hSAC2, phosphatidylinositide phosphatase SAC2, and MSTP007.
