Structural and Functional Analysis of a β2-Adrenergic Receptor Complex with GRK5. [PDF]

, 2017
The phosphorylation of agonist-occupied G-protein-coupled receptors (GPCRs) by GPCR kinases (GRKs) functions to turn off G-protein signaling and turn on arrestin-mediated signaling.

β2-adrenergic receptor promotes liver regeneration partially through crosstalk with c-met

Cell Death and Disease, 2022
The β2-adrenergic receptor (β2AR) is a G protein-coupled receptor (GPCR) that mediates the majority of cellular responses to external stimuli. Aberrant expression of β2AR results in various pathophysiological disorders, including tumorigenesis, but ...

Reciprocal regulation of PKA and rac signaling [PDF]

, 2013
Activated G protein-coupled receptors (GPCRs) and receptor tyrosine kinases relay extracellular signals through spatial and temporal controlled kinase and GTPase entities.

A G protein-gated K channel is activated via beta 2-adrenergic receptors and G beta gamma subunits in Xenopus oocytes [PDF]

, 1995
In many tissues, inwardly rectifying K channels are coupled to seven- helix receptors via the Gi/Go family of heterotrimeric G proteins. This activation proceeds at least partially via G beta gamma subunits.

Homologous and Heterologous Phosphorylations of Human Histamine H1 Receptor in Intact Cells

Journal of Pharmacological Sciences, 2004
Homologous and heterologous phosphorylations of histamine H1 receptor (H1R) in intact cells were investigated using Chinese hamster ovary cells stably co-expressing c-myctagged human histamine H1 and muscarinic M3 receptors. Increase in histamine-induced

Novel inhibitors of phosphorylation independent activity of GRK2 modulate cAMP signaling

Pharmacology Research & Perspectives, 2022
G protein‐coupled receptors kinase 2 (GRK2) plays a major role in receptor regulation and, as a consequence, in cell biology and physiology. GRK2‐mediated receptor desensitization is performed by its kinase domain, which exerts receptor phosphorylation ...

Cardiac GRK2 Protein Levels Show Sexual Dimorphism during Aging and Are Regulated by Ovarian Hormones

Cells, 2021
Cardiovascular disease (CVD) risk shows a clear sexual dimorphism with age, with a lower incidence in young women compared to age-matched men. However, this protection is lost after menopause. We demonstrate that sex-biased sensitivity to the development

G Protein–Coupled Receptor Kinase 2 [PDF]

Circulation Research, 2014
Heart failure (HF) causes a tremendous burden on the worldwide healthcare system, affecting >23 million people. There are many cardiovascular disorders that contribute to the development of HF and multiple risk factors that accelerate its occurrence, but regardless of its underlying cause, HF is characterized by a marked decrease in myocardial ...

Ubiquitin plays an atypical role in GPCR-induced p38 MAP kinase activation on endosomes. [PDF]

, 2015
Protease-activated receptor 1 (PAR1) is a G protein-coupled receptor (GPCR) for thrombin and promotes inflammatory responses through multiple pathways including p38 mitogen-activated protein kinase signaling.

Role of the Amino Terminus of G Protein-Coupled Receptor Kinase 2 in Receptor Phosphorylation [PDF]

Biochemistry, 2009
G protein-coupled receptor kinases (GRKs) specifically phosphorylate activated G protein-coupled receptors. While the X-ray crystal structures of several GRKs have been determined, the mechanism of interaction of GRK with GPCRs is currently unknown. To further characterize the role of the GRK2 amino terminus in receptor interaction and phosphorylation,
