Background
| Function | FUNCTION: 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). {ECO:0000269|PubMed:26774281, ECO:0000269|PubMed:31091439, ECO:0000269|PubMed:9038203}. |
