Symbol/Gene Name:  PIP4K2B

Alias:  Phosphatidylinositol 5-phosphate 4-kinase type-2 beta,1-phosphatidylinositol 5-phosphate 4-kinase 2-beta,Diphosphoinositide kinase 2-beta,Phosphatidylinositol 5-phosphate 4-kinase type II beta,PI(5)P 4-kinase type II beta,PIP4KII-beta,PtdIns(5)P-4-kinase isoform 2-beta

Uniprot: P78356

Background: Participates in the biosynthesis of phosphatidylinositol 4,5-bisphosphate (PubMed:9038203, PubMed:26774281). Preferentially utilizes GTP, rather than ATP, for PI(5)P phosphorylation and its activity reflects changes in direct proportion to the physiological GTP concentration (PubMed:26774281). Its GTP-sensing activity is critical for metabolic adaptation (PubMed:26774281). PIP4Ks negatively regulate insulin signaling through a catalytic-independent mechanism. They interact with PIP5Ks and suppress PIP5K-mediated PtdIns(4,5)P2 synthesis and insulin-dependent conversion to PtdIns(3,4,5)P3 (PubMed:31091439).
