Phosphatidylinositol-5-phosphate 4-kinase type-2 beta is an enzyme that in humans is encoded by the PIP4K2B gene.[1][2][3][4]

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.[4]

Interactions

PIP4K2B has been shown to interact with TNFRSF1A.[1]
