General description【一般描述】
Although PI(4,5)P2 is a minor component of cell membranes, it plays a critical role as a substrate for a number of important signaling proteins. PI(4,5)P2 is an intermediate in the IP3/DAG pathway where it is hydrolyzed by phospholipase C to liberate the second messengers, inositol 1,4,5-triphosphate (IP3) and diacylglycerol (DAG). PI(4,5)P2 is also a substrate for PI 3-kinase where it is phosphorylated to PI(3,4,5)P3, an activator of downstream signaling components such as the protein kinase AKT.
Phosphatidylinositol 4,5-bisphosphate (PIP2) is a negatively charged phospholipid, abundant in the plasma membrane.
Application【应用】
18:0-20:4 PI(4,5)P2 or 1-stearoyl-2-arachidonoyl-sn-glycero-3-phospho-(1′-myo-inositol-4′,5′-bisphosphate) (ammonium salt) has been used:
  • in cryo-electron microscopy (cryo-EM) grid preparation
  • in host 1-O-1-(Z)-octadecenyl-2-arachidonoyl-sn-glycero-3-phosphocholine (plasmenyl-SAPC) small unilamellar vesicles (SUVs) in the presence of H2O2 to activate cyt c plasmalogenase activity
  • to study whether acyl chain types affect phosphatidylinositol 4,5-bisphosphate (PIP2) cluster formation
