Activation of a variety of cell surface receptors results in a biphasic increase in the cytoplasmic Ca 2+ concentration, due to the release or mobilization of intracellular Ca 2+ stores and to the entry of Ca 2+ from the extracellular space. Inorganic phosphate (Pi) is an essential structural element of bones and teeth, and it is one of the most pervasive inhibitors of cellular enzymes (1, 2). Another molecular mechanism could be through its antioxidant activity. com/supplements/inositol/#ref186. Moreover, mutants defective in PKC signaling exhibit inositol auxotrophy Fluorescent lipid-associated reporters (FLAREs), provided by the laboratory of Scott Emr, enabled the in vivo localization of pools of PI 4-phosphate (PI4P) and PI(4,5)P2, known to be involved in PKC signaling in yeast. Polyphosphoinositides (PPIs) became famous for their role in inositol-1,4,5-trisphosphate (InsP3) mediated-Ca (2+) signalling in mammalian cells, generated through signal-activated phospholipase C (PLC) hydrolysis of the minor membrane lipid, phosphatidylinositol-4,5-bisphosphate. InsP3 5-phosphatases hydrolyze Ins(1,4,5)P3, which mobilizes intracellular calcium and acts as a second messenger mediating cell responses to various stimulation.
