PIP2 regulates the organization, polymerization, and branching of filamentous actin (F-actin) via direct binding to F-actin regulatory proteins. The first evidence that indicated phosphoinositides(PIs) (especially PI(4,5)P2) are important during the exocytosis process was in 1990. Emberhard et al. found that the application of PI-specific phospholipase C into digitonin-permeabilized chromaffin cells decreased PI levels, and in… Webb9 feb. 2015 · Hydrolysis of PIP 2 releases inositol-1,4,5-triphosphate (IP 3) from the membrane, activating IP 3 receptors on the smooth endoplasmic reticulum (ER) and facilitating a release of intracellular...
