Descriptions
PLCB1 catalyzes the hydrolysis of 1-phosphatidylinositol 4,5-bisphosphate into diacylglycerol (DAG) and inositol 1,4,5-trisphosphate (IP3) and mediates intracellular signaling downstream of G protein-coupled receptors. Autoinhibitory region is a portion of the linker that separates the conserved X and Y boxes comprising the catalytic TIM barrel, at residues 468-539, and occludes the active site of PLCB1. The active site of a PLC isozyme toward phospholipid membranes should force the negatively charged X/Y linker away from the active site, therein relieving autoinhibition of the enzyme.
