Regulation of protein kinase C activity by gangliosides.
The activity of protein kinase C (Ca2+/phospholipid-dependent enzyme) in the presence of phosphatidylserine and its physiological regulator, diacylglycerol, could be suppressed by a mixture of brain gangliosides. Half-maximal inhibition was observed at 30 microM and was nearly complete at 100 microM. Inhibition was observed at all concentrations of Ca2+ between 10(-8) and 10(-4) M. Inhibition o...
متن کاملRegulation of phospholipase D2 activity by protein kinase C alpha.
It has been well documented that protein kinase C (PKC) plays an important role in regulation of phospholipase D (PLD) activity. Although PKC regulation of PLD1 activity has been studied extensively, the role of PKC in PLD2 regulation remains to be established. In the present study it was demonstrated that phorbol 12-myristate 13-acetate (PMA) induced PLD2 activation in COS-7 cells. PLD2 was al...

متن کاملRegulation of exocytosis by protein kinase C.
PKC (protein kinase C) has been known for many years to modulate regulated exocytosis in a wide variety of cell types. In neurons and neuroendocrine cells, PKC regulates several different stages of the exocytotic process, suggesting that these multiple actions of PKC are mediated by phosphorylation of distinct protein targets. In recent years, a variety of exocytotic proteins have been identifi...
متن کاملRegulation of protein kinase C.
Protein kinase C has been in the spotlight since the discovery two decades ago that it is activated by the lipid second messenger diacylglycerol. Despite protein kinase C's enduring stage presence, the regulation and specific roles of its isozymes in defined cellular processes are still under intense investigation. Elucidation of the structures of protein kinase C's regulatory modules, the disc...
