Phospholipase C (PLC) plays an essential role in cell metabolism, as it hydrolyzes membrane‐bound phospholipid phosphatidylinositol 4,5‐biphosphate (PIP2) into two second messengers, inositol 1,4,5‐triphosphate (IP3) and diacylglyc‐ erol (DAG) (5). A growing body of evidence indicates that increased
