Phospholipase C Regulation of Phosphatidylinositol 3,4,5-trisphosphate-mediated Chemotaxis□V
Generation of a phosphatidylinositol 3,4,5-trisphosphate [PI(3,4,5)P3] gradient within the plasma membrane is important for cell polarization and chemotaxis in many eukaryotic cells. The gradient is produced by the combined activity of phosphatidylinositol 3-kinase (PI3K) to increase PI(3,4,5)P3 on the membrane nearest the polarizing signal and PI(3,4,5)P3 dephosphorylation by phosphatase and t...

متن کاملPhospholipase D is Dispensable for Epidermal Growth Factor-Induced Chemotaxis.
α-Synuclein (α-Syn) is implicated in several neurodegenerative disorders, including Parkinson's disease, known collectively as the synucleinopathies. α-Syn is known to be secreted from the cells and may contribute to the progression of the disease. Although extracellular α-Syn is shown to impair platelet-derived growth factor-induced chemotaxis, molecular mechanism of α-Syn-induced motility fai...
متن کاملPhospholipase A 2 and Phospholipase C Activities of Platelets DIFFERENTIAL
Deoxycholate treatment of horse platelets previously labeled in their phospholipids with [“Clarachidonate produces selective conversion of [“Clphosphatidylinositol (PI) to [‘4C]1,2-diacylglycerol. This phospholipase C activity, which has a pH optimum of 7.5, is specific for phosphatidylinositol since other phospholipids or neutral lipids are not affected. Although exogenous Ca2+ is not required...
متن کاملLocalization and possible functions of phospholipase D isozymes.
The activation of PLD is believed to play an important role in the regulation of cell function and cell fate by extracellular signal molecules. Multiple PLD activities have been characterized in mammalian cells and, more recently, several PLD genes have been cloned. Current evidence indicates that diverse PLD activities are localized in most, if not all, cellular organelles, where they are like...
