Organization and alternative splicing of the murine phospholipase D2 gene.
Phospholipase D (PLD) catalyses the hydrolysis of phosphatidylcholine, generating phosphatidic acid and choline. Mammalian PLD activity derives from a family of membrane-associated enzymes that are activated by a wide variety of signal transduction events. cDNA species encoding human, mouse and rat PLD1 and PLD2 have recently been reported. In this study we undertook to determine the organizati...
متن کاملMastoparan selectively activates phospholipase D2 in cell membranes.
Both known isoforms of phospholipase (PL) D, PLD1 and PLD2, require phosphatidylinositol 4,5-bisphosphate for activity. However, PLD2 is fully active in the presence of this phospholipid, whereas PLD1 activation is dependent on additional factors such as ADP-ribosylation factor-1 (ARF-1) and protein kinase Calpha. We find that mastoparan, an activator of G(i) and mast cells, stimulates an intri...
متن کاملRegulation of Phospholipase D2 Activity by Protein Kinase C *
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 12myristate 13-acetate (PMA) induced PLD2 activation in COS-7 cells. PLD2 was als...

متن کاملSelective activation of phospholipase D2 by unsaturated fatty acid.
Although oleate has been implicated in the regulation of phospholipase D (PLD) activity, the molecular identity of the oleate-stimulated PLD is still poorly understood. We now report that oleate selectively stimulates the enzymatic activity of PLD2 but not of PLD1, with an optimal concentration of 20 microM in vitro. Intriguingly, phosphatidylinositol 4,5-bisphosphate (PIP2) synergistically sti...
