General description

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. The dioctanoyl derivative of PI(4,5)P2 is more water soluble than its long chain counterparts.

Application

08:0 PI(4,5)P2 is suitable for use to identify its binding site in transient receptor potential vanilloid 4 (TRPV4 N) terminus. It has been used in in vitro binding assay to determine the binding of G-protein coupled receptor kinases (GRKs) and β2-adrenergic receptor (β2AR).

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
