Frontiers in Cell and Developmental Biology, 2021 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 ...

Frontiers in Physiology, 2021 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.

Activation by G protein beta gamma subunits of beta-adrenergic and muscarinic receptor kinase. [PDF]
Journal of Biological Chemistry, 1993 We have shown previously that GTP-binding regulatory protein (G protein) beta gamma subunits stimulate the agonist- or light-dependent phosphorylation of muscarinic acetylcholine receptors (mAChRs) and rhodopsin by a protein kinase partially purified from porcine brain (mAChR kinase) but not the phosphorylation of rhodopsin by rhodopsin kinase (Haga, K.

Functional desensitization of the isolated beta-adrenergic receptor by the beta-adrenergic receptor kinase: potential role of an analog of the retinal protein arrestin (48-kDa protein). [PDF]
Proceedings of the National Academy of Sciences, 1987 The beta-adrenergic receptor kinase is an enzyme, possibly analogous to rhodopsin kinase, that multiply phosphorylates the beta-adrenergic receptor only when it is occupied by stimulatory agonists. Since this kinase may play an important role in mediating the process of homologous, or agonist-specific, desensitization, we investigated the functional ...

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.

Beta-adrenergic receptor kinase. Agonist-dependent receptor binding promotes kinase activation.
Journal of Biological Chemistry, 1993 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 ...

Altered expression of beta-adrenergic receptor kinase and beta 1-adrenergic receptors in the failing human heart. [PDF]
Circulation, 1993 BACKGROUND In chronic heart failure, the positive inotropic effects of beta-adrenergic receptor agonists are greatly reduced, in part as a result of two alterations of the cardiac beta-adrenergic receptors: loss of their function (receptor uncoupling) and reduction of their number (downregulation).

The β-Adrenergic Receptor Kinase (GRK2) Is Regulated by Phospholipids [PDF]
Journal of Biological Chemistry, 1995 The beta-adrenergic receptor kinase (beta ARK) is a member of growing family of G protein coupled receptor kinases (GRKs). beta ARK and other members of the GRK family play a role in the mechanism of agonist-specific desensitization by virtue of their ability to phosphorylate G protein-coupled receptors in an agonist-dependent manner.
