WebApr 7, 2024 · Introduction. Nonalcoholic fatty liver disease (NAFLD), characterized by excessive fat accumulation in hepatocytes, was suggested to be the most common cause of chronic liver lesions. 1 Recent surveys have demonstrated that NAFLD is prevalent worldwide, specifically, ∼ 31.79 %, 2 30.45%, 2 and 27.37% 2 of the population in the … 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 … See more 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. … See more Activation Receptors that activate this pathway are mainly G protein-coupled receptors coupled to the Gαq subunit, including: • See more • Glycosylphosphatidylinositol diacylglycerol-lyase EC 4.6.1.14 A trypanosomal enzyme. • Phosphatidylinositol diacylglycerol-lyase EC See more In mammals, PLCs share a conserved core structure and differ in other domains specific for each family. The core enzyme includes a split triosephosphate isomerase (TIM) barrel See more 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 … See more 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 … See more
Phosphoinositide phospholipase C - Wikipedia
Phospholipase C performs a catalytic mechanism, depleting PIP2 and generating inositol trisphosphate (IP3) and diacylglycerol (DAG). Depletion of PIP2 inactivates numerous effector molecules in the plasma membrane, most notably PIP2 dependent channels and transporters responsible for setting the cell's membrane potential.
