WebPLC hydrolyzes phosphatidylinositol 4,5-bisphosphate [PI(4,5)P 2] in the plasma membrane to produce diacylgycerol and inositol 1,4,5-trisphosphate [Ins(1,4,5)P 3]. Ins(1,4,5)P 3 binding to Ins(1,4,5)P 3 receptors then triggers release of Ca 2+ from internal endoplasmic reticulum stores and initiates store-operated Ca 2+ entry.
