β-adrenergic signaling inhibits Gq-dependent protein kinase D activation by preventing protein kinase D translocation.

RATIONALE Both β-adrenergic receptor (β-AR) and Gq-coupled receptor (GqR) agonist-driven signaling play key roles in the events, leading up to and during cardiac dysfunction. How these stimuli interact at the level of protein kinase D (PKD), a nodal point in cardiac hypertrophic signaling, remains unclear. OBJECTIVE To assess the spatiotemporal dynamics of PKD activation in response to β-AR s...

Regulation of β-Adrenergic Receptor Signaling by S-Nitrosylation of G-Protein-Coupled Receptor Kinase 2

beta-adrenergic receptors (beta-ARs), prototypic G-protein-coupled receptors (GPCRs), play a critical role in regulating numerous physiological processes. The GPCR kinases (GRKs) curtail G-protein signaling and target receptors for internalization. Nitric oxide (NO) and/or S-nitrosothiols (SNOs) can prevent the loss of beta-AR signaling in vivo, but the molecular details are unknown. Here we sh...

Protein Kinase C Selectively Regulates Protein Kinase D-Dependent Activation of NF- B in Oxidative Stress Signaling

Protein kinase D (PKD) participates in activation of the transcription factor NFB (nuclear factor B) in cells exposed to oxidative stress, leading to increased cellular survival. We previously demonstrated that phosphorylation of PKD at Tyr463 in the PH (pleckstrin homology) domain is mediated by the Src-Abl pathway and that it is necessary for PKD activation and subsequent NFB induction. Here ...

Protein Kinase D

Protein kinase Cs (PKCs) are activated by antigen receptors in lymphocytes, but little is known about proximal targets for PKCs in antigen receptor-mediated responses. In this report, we define a role for diacylglycerol-regulated PKC isoforms in controlling the activity of the serine/threonine kinase protein kinase D (PKD; also known as PKC mu) in T cells, B cells, and mast cells. Antigen recep...

Activation of protein kinase A increases phospholipase D activity and inhibits phospholipase D activation by acetylcholine in tracheal smooth muscle.

Increased cAMP by stimulation of adenylyl cyclase with forskolin or by beta-adrenoceptor activation with isoproterenol increased phospholipase D (PLD) activity in tracheal smooth muscle strips. PLD activity was measured by the accumulation of phosphatidylethanol. A linear increase in the concentration of phosphatidylethanol was observed over 20 min in muscle strips treated with either forskolin...
