Reduced beta-adrenergic receptor activation decreases G-protein expression and beta-adrenergic receptor kinase activity in porcine heart. [PDF]
To determine whether beta-adrenergic receptor agonist activation influences guanosine 5'-triphosphate-binding protein (G-protein) expression and beta-adrenergic receptor kinase activity in the heart, we examined the effects of chronic beta 1-adrenergic receptor antagonist treatment (bisoprolol, 0.2 mg/kg per d i.v., 35 d) on components of the ...

Rapid agonist‐induced beta‐adrenergic receptor kinase translocation in C6 glioma cells [PDF]
Exposure of C6 glioma cells to 1 μM isoproterenol leads to fast desensitization of the β‐adrenergic receptor/adenylyl cyclase system and transient receptor sequestration. It also triggers a very rapid and transient translocation to the plasma membrane or β‐adrenergic receptor kinase (βARK), a specific cytoplasmic kinase that phosphorylates only the ...

The NADPH oxidase NOX4 regulates redox and metabolic homeostasis preventing HCC progression
Loss of NOX4 in HCC tumor cells induces metabolic reprogramming in a Nrf2/MYC‐dependent manner to promote HCC progression. Abstract Background and Aims The NADPH oxidase NOX4 plays a tumor‐suppressor function in HCC. Silencing NOX4 confers higher proliferative and migratory capacity to HCC cells and increases their in vivo tumorigenic potential in ...

Mechanism of beta-adrenergic receptor kinase activation by G proteins
The beta-adrenergic receptor kinase (beta-ARK) specifically phosphorylates the activated form of various G protein-coupled receptors such as the beta 2-adrenergic receptor (beta 2-AR). Recently, G protein beta gamma subunits have been demonstrated to activate beta-ARK-mediated receptor phosphorylation.

Regulation of Neuromodulator Receptor Efficacy - Implications for Whole-Neuron and Synaptic Plasticity [PDF]
Membrane receptors for neuromodulators (NM) are highly regulated in their distribution and efficacy - a phenomenon which influences the individual cell's response to central signals of NM release.

Gravin orchestrates protein kinase A and 2-adrenergic receptor signaling critical for synaptic plasticity and memory [PDF]
A kinase-anchoring proteins (AKAPs) organize compartmentalized pools of protein kinase A (PKA) to enable localized signaling events within neurons. However, it is unclear which of the many expressed AKAPs in neurons target PKA to signaling complexes ...

Beta-adrenergic receptor kinase. Agonist-dependent receptor binding promotes kinase activation.
The beta-adrenergic receptor kinase (beta ARK) specifically phosphorylates the activated form of multiple receptors such as the beta 2-adrenergic receptor (beta 2 AR) and rhodopsin. beta ARK also phosphorylates synthetic peptides, albeit with an approximately 10(4)-10(7)-fold lower Vmax/Km ratio as compared to receptors, with a clear preference for ...
