Phospholipase C, Phosphatidylinositol specific from Bacillus cereus Physiologic implications of phosphoinositides and phospholipase C in the regulation of insulin secretion. Semantic Scholar This diagram illustrates a signaling pathway in which a messenger molecule binds to a receptor on the cell membrane, activating an associated G protein. Once triggered, the G protein's subunit exchanges GDP for GTP Phospholipase C (PLC). Diacylglycerol (DAG) and Inositol 1,4,5 trisphosphate. Protein kinase C (PKC). Vector illustration.
