Beta-adrenergic receptor kinase: identification of a novel protein kinase that phosphorylates the agonist-occupied form of the receptor. [PDF]
Agonist-promoted desensitization of adenylate cyclase is intimately associated with phosphorylation of the beta-adrenergic receptor in mammalian, avian, and amphibian cells. However, the nature of the protein kinase(s) involved in receptor phosphorylation remains largely unknown.

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 β-Adrenergic Receptor Is a Substrate for the Insulin Receptor Tyrosine Kinase [PDF]
G-protein-linked receptors and intrinsic tyrosine-kinase growth receptors represent two prominent modalities in cell signaling. Cross-regulation among members of both receptor superfamilies has been reported, including the counter-regulatory effects of insulin on beta-adrenergic catecholamine action.

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 ...

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

The β-Adrenergic Receptor Kinase (GRK2) Is Regulated by Phospholipids [PDF]
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.

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 ...
