Descripción general

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.

Aplicación

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

Syntaxin (STX) is a N-ethylmaleimide-sensitive factor attachment protein receptor (SNARE) protein that binds to the plasma membrane and regulates ion channels and neurotransmitter transporters. Experiments have established the involvement of the N-terminal segment of STX in direct protein-protein interactions and

In β-cells, syntaxin (Syn)-1A interacts with SUR1 to inhibit ATP-sensitive potassium channels (KATP channels). PIP2 binds the Kir6.2 subunit to open KATP channels. PIP2 also modifies Syn-1A clustering in plasma membrane (PM) that may alter Syn-1A actions on PM proteins
