We investigated the role of phospholipase D (PLD) and its product phosphatidic acid (PA) in myogenic differentiation of cultured L6 rat skeletal myoblasts. Arginine-vasopressin (AVP), a differentiation inducer, rapidly activated PLD in a Rho-dependent way, as shown by almost total suppression of activation by C3 exotoxin pretreatment. Addition of 1-butanol, which selectively inhibits PA product...

N-acylethanolamines (NAEs) are membrane-derived lipids that are utilized as signaling molecules in the nervous system (e.g., the endocannabinoid anandamide). An N-acyl phosphatidylethanolamine phospholipase D (NAPE-PLD) that catalyzes formation of NAEs was recently identified as a member of the zinc metallohydrolase family of enzymes. NAPE-PLD(-/-) mice have greatly reduced brain levels of long...

Rapid activation of phospholipase D (PLD) in response to cell stimulation was recently demonstrated in many systems, raising the hypothesis that PLD participates in transduction of extracellular signals across the plasma membrane. In the present study, we describe the identification of a neutral PLD activity in purified rat brain synaptic plasma membranes, and the in vitro conditions required t...

Angiotensin II (Ang II)-induced phospholipase D (PLD) activity is greater in aortic smooth muscle from spontaneously hypertensive rats (SHR) versus normotensive Wistar-Kyoto rats (WKY). Whether and how this signaling pathway is altered in preglomerular microvascular smooth muscle cells (PGSMCs), a cell type that may participate in genetic hypertension, is unknown. The goals of the present study...

Yeast phosphatidylinositol transfer protein (Sec14p) is essential for Golgi function and cell viability. We now report a characterization of five yeast SFH (Sec Fourteen Homologue) proteins that share 24-65% primary sequence identity with Sec14p. We show that Sfh1p, which shares 64% primary sequence identity with Sec14p, is nonfunctional as a Sec14p in vivo or in vitro. Yet, SFH proteins sharin...

The D2 dopamine receptor isoforms signal to a variety of cellular effectors in both the central nervous system and periphery. Two alternative splice forms of the D2 dopamine receptor exist, the D2s (short) and D2l (long), which has an insertion of 29 amino acids in the third intracellular loop (). In cells of the anterior lobe of the pituitary, D2 dopamine receptors (both forms) are present on ...

The BBSome is a complex of seven proteins, including BBS4, that is cycled through cilia by intraflagellar transport (IFT). Previous work has shown that the membrane-associated signaling protein phospholipase D (PLD) accumulates abnormally in cilia of Chlamydomonas reinhardtii bbs mutants. Here we show that PLD is a component of wild-type cilia but is enriched ∼150-fold in bbs4 cilia; this accum...

The generation of diradylglycerol (DRG) and phosphatidic acid (PdtOH) was investigated in neutrophils primed with granulocyte-macrophage colony-stimulating factor (GM-CSF). Mass accumulation of DRG and PdtOH was measured using reversed-phase high performance liquid chromatography and thin layer chromatography, respectively. GM-CSF had no direct effect on the levels of PdtOH and DRG, but it incr...

Activation of group I metabotropic glutamate receptors (mGluRs) elicits persistent ictaform discharges in guinea pig hippocampal slices, providing an in vitro model of epileptogenesis. The induction of these persistent ictaform bursts is prevented by l-cysteine sulfinic acid (CSA), an agonist at phospholipase D (PLD)-coupled mGluRs. Studies described herein examined the role of protein kinase C...
