Phospholipase C (PLC) is a class of membrane-associated enzymes that cleave phospholipids just before the phosphate group (see figure). It is most commonly taken to be synonymous with the human forms of this enzyme, which play an important role in eukaryotic cell physiology, in particular signal … 展开
Mammalian variants
The extensive number of functions exerted by the PLC reaction requires that it be strictly regulated and able to respond to multiple extra- and intracellular inputs with appropriate kinetics. This … 展开The primary catalyzed reaction of PLC occurs on an insoluble substrate at a lipid-water interface. The residues in the active site are conserved in all PLC isotypes. In animals, PLC selectively … 展开
Activation
Receptors that activate this pathway are mainly G protein-coupled receptors coupled to the Gαq subunit, including:
• 5-HT2 展开• Glycosylphosphatidylinositol diacylglycerol-lyase EC 4.6.1.14 A trypanosomal enzyme.
• Phosphatidylinositol diacylglycerol-lyase EC 4.6.1.13 Another related bacterial enzyme 展开In mammals, PLCs share a conserved core structure and differ in other domains specific to each family. The core enzyme includes a split triosephosphate isomerase (TIM) barrel, 展开
Phosphoinositide-specific phospholipase C (PLC) is a key player in cell signaling processes. When cells encounter signals like hormones or growth factors, PLC breaks down a molecule called PIP2 to produce new signaling molecules. PIP2 is a type of molecule found … 展开
PLC cleaves the phospholipid phosphatidylinositol 4,5-bisphosphate (PIP2) into diacyl glycerol (DAG) and inositol 1,4,5-trisphosphate (IP3). Thus PLC has a profound … 展开
