Phosphatidylinositol-4-phosphate is one of the in vitro substrates for PI3-kinases. Phosphatidylinositol 3-kinase is a lipid kinase that phosphorylates the inositol ring of phosphatidylinositol-4-phosphate and related compounds at the 3’-OH position. PIP can be used as a substrate for PI3K lipid kinase activity assay together with a mix of PI, PIP2, PC, PE, PS and SM.
