The protein encoded by this gene catalyzes the phosphorylation of phosphatidylinositol 4-phosphate on the fifth hydroxyl of the myo-inositol ring to form phosphatidylinositol 4,5-bisphosphate. This gene is a member of the phosphatidylinositol-4-phosphate 5-kinase family. The encoded protein sequence does not show similarity to other kinases, but the protein does exhibit kinase activity. Additionally, the encoded protein interacts with p55 TNF receptor.^[8]
