[Phosphoinositide-specific phospholipase C in mammalian cells: structure, properties, and function].
Phospholipase C (PLC) catalyzes the hydrolysis of phosphatidylinositol-4,5-bisphosphate (PIP2) to yield diacylglycerol (DAG) and inositol-1,4,5-triphosphate (IP3). Phospholipase C activities have been described in several organisms, including bacteria, yeast, plants, and mammals. In mammalian cells, PLC (PLC-beta, PLC-gamma, PLC-delta, PLC-epsilon, PLC-zeta, and PLC-eta isoforms) has been implicated in intracellular signal transduction, vesicle transport, endocytosis, exocytosis, ion channel function, mitosis, cytoskeletal reorganization, and neuronal signal transduction. Mammalian phospholipase C is regulated by many factors, including calcium ions, receptor tyrosine kinases, and small G-proteins of the Ras and Rho families. In this review the structure and biological function of PLC are discussed.
