Overexpression of beta-arrestin and beta-adrenergic receptor kinase augment desensitization of beta 2-adrenergic receptors.

Journal of Biological Chemistry, 1993
Receptor-specific or homologous desensitization of beta 2-adrenergic receptors is thought to be effected via phosphorylation of the receptor by the beta-adrenergic receptor kinase (beta ARK), followed by binding of beta-arrestin. We have generated stably transfected Chinese hamster ovary cell lines overexpressing either of the two regulatory proteins ...

A beta-adrenergic receptor kinase dominant negative mutant attenuates desensitization of the beta 2-adrenergic receptor.

Journal of Biological Chemistry, 1994
The beta-adrenergic receptor kinase (beta ARK) specifically phosphorylates the activated form of the beta 2-adrenergic receptor (beta 2AR) and related G protein-coupled receptors. To further elucidate the role of beta ARK in receptor desensitization, we generated a beta ARK dominant negative mutant by converting an invariant lysine residue in the ...

Cloning, expression, and chromosomal localization of beta-adrenergic receptor kinase 2. A new member of the receptor kinase family

Journal of Biological Chemistry, 1991
The beta-adrenergic receptor kinase (beta ARK) specifically phosphorylates the agonist-occupied form of the beta-adrenergic and related G protein-coupled receptors. Structural features of this enzyme have been elucidated recently by the isolation of a cDNA that encodes bovine beta ARK.

Comparative rates of desensitization of beta-adrenergic receptors by the beta-adrenergic receptor kinase and the cyclic AMP-dependent protein kinase. [PDF]

Proceedings of the National Academy of Sciences, 1991
Three separate processes may contribute to rapid beta-adrenergic receptor desensitization: functional uncoupling from the stimulatory guanine nucleotide-binding protein Gs, mediated by phosphorylation of the receptors by two distinct kinases, the specific beta-adrenergic receptor kinase (beta ARK) and the cyclic AMP-dependent protein kinase A (PKA), as

Reduced beta-adrenergic receptor activation decreases G-protein expression and beta-adrenergic receptor kinase activity in porcine heart. [PDF]

Journal of Clinical Investigation, 1995
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 ...

The β-blocker Nebivolol Is a GRK/β-arrestin Biased Agonist [PDF]

, 2013
Nebivolol, a third generation β-adrenoceptor (β-AR) antagonist (β-blocker), causes vasodilation by inducing nitric oxide (NO) production. The mechanism via which nebivolol induces NO production remains unknown, resulting in the genesis of much of the ...

G-Protein Inwardly Rectifying Potassium Channel 1 (GIRK1) Knockdown Decreases Beta-Adrenergic, MAP Kinase and Akt Signaling in the MDA-MB-453 Breast Cancer Cell Line

Breast Cancer: Basic and Clinical Research, 2008
Previous data from our laboratory have indicated that there is a functional link between the beta-adrenergic receptor signaling pathway and the G-protein inwardly rectifying potassium channel (GIRK1) in breast cancer cell lines and that these pathways ...

Mechanism of β-Adrenergic Receptor Desensitization in Cardiac Hypertrophy Is Increased β-Adrenergic Receptor Kinase [PDF]

Journal of Biological Chemistry, 1997
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

β-Adrenergic Receptor Kinase (GRK2) Colocalizes with β-Adrenergic Receptors during Agonist-induced Receptor Internalization [PDF]

Journal of Biological Chemistry, 1997
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

Structure of the human gene encoding the beta-adrenergic receptor kinase.

Journal of Biological Chemistry, 1994
The beta-adrenergic receptor kinase (beta ARK) specifically phosphorylates the agonist-occupied forms of the beta 2-adrenergic receptor and related G protein-coupled receptors. beta ARK is one of the best characterized members of a growing family of G protein-coupled receptor kinases.
