Desensitization of the beta-adrenergic receptor, a receptor which is coupled to the stimulation of adenylate cyclase, may be regulated via phosphorylation by a unique protein kinase. This recently discovered enzyme, known as the beta-adrenergic receptor kinase, only phosphorylates the agonist-occupied form of the beta-adrenergic receptor.

Harmine and 7,8-dihydroxyflavone synergistically suitable for amyotrophic lateral sclerosis management: An in silico study [PDF]
Introduction: Amyotrophic lateral sclerosis (ALS) is a fatal neurological disease characterized by progressive degeneration of both upper and lower motor neurons, resulting in paralysis and eventually leads to death from respiratory failure typically ...

Heart failure development is characterized by persistent inflammation and progressive fibrosis owing to chronic catecholamine stress. In a chronic stress state, elevated catecholamines result in the overstimulation of beta-adrenergic receptors (βARs ...

We previously showed that the beta-3 adrenergic receptor (BAR3) is expressed in most segments of the nephron where its agonism promotes a potent antidiuretic effect.

Rapid desensitization of neonatal rat liver beta-adrenergic receptors. A role for beta-adrenergic receptor kinase. [PDF]
Exposure of beta-adrenergic receptors (BAR) to agonists often leads to a rapid loss of receptor responsiveness. The proposed mechanisms of such rapid receptor desensitization include receptor phosphorylation by either cAMP-dependent protein kinase or the specific beta-adrenergic receptor kinase (BARK), leading to functional uncoupling from adenylyl ...

β-Adrenergic Receptor Kinase (GRK2) Colocalizes with β-Adrenergic Receptors during Agonist-induced Receptor Internalization [PDF]
Rapid regulation of G protein-coupled receptors appears to involve agonist-promoted receptor phosphorylation by G protein-coupled receptor kinases (GRKs). This is followed by binding of uncoupling proteins termed arrestins and transient receptor internalization. In this report we show that the beta-adrenergic receptor kinase (betaARK-1 or GRK2) follows

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 β-Adrenergic Receptor Desensitization in Cardiac Hypertrophy Is Increased β-Adrenergic Receptor Kinase [PDF]
Pressure overload cardiac hypertrophy in the mouse was achieved following 7 days of transverse aortic constriction. This was associated with marked beta-adrenergic receptor (beta-AR) desensitization in vivo, as determined by a blunted inotropic response to dobutamine. Extracts from hypertrophied hearts had approximately 3-fold increase in cytosolic and

Inhibition of the beta-adrenergic receptor kinase by polyanions.
The beta-adrenergic receptor kinase, which specifically phosphorylates the agonist-occupied beta-adrenergic receptor, is strongly inhibited by polyanions. Heparin and dextran sulfate inhibit the enzyme with an IC50 of approximately 0.15 microM. De-N-sulfated heparin is approximately 8-fold less potent.
