Insulin inhibits cardiac contractility by inducing a Gi-biased β2-adrenergic signaling in hearts. [PDF]
Insulin and adrenergic stimulation are two divergent regulatory systems that may interact under certain pathophysiological circumstances. Here, we characterized a complex consisting of insulin receptor (IR) and β2-adrenergic receptor (β2AR) in the heart.

Aims The effects of GRK2 inhibition on myocardial metabolism in heart failure (HF) are unchartered. In this work, we evaluated the impact of pharmacological inhibition of GRK2 by a cyclic peptide, C7, on metabolic, biochemical, and functional phenotypes ...

βARKct gene-therapy improves β2-adrenergic receptor-dependent neoangiogenesis following hindlimb ischemia [PDF]
Following hindlimb ischemia (HI) increased catecholamine levels within the ischemic muscle can cause dysregulation of β2-adrenergic receptor (β2AR) signaling leading to reduced revascularization.

The potential for biased signalling in the P2Y receptor family of GPCRs
The purinergic receptor family is primarily activated by nucleotides, and contains members of both the G protein coupled‐receptor (GPCR) superfamily (P1 and P2Y) and ligand‐gated ion channels (P2X). The P2Y receptors are widely expressed in the human body, and given the ubiquitous nature of nucleotides, purinergic signalling is involved with a plethora

Low GRK2 Underlies Hyperalgesic Priming by Glial Cell-Derived Neurotrophic Factor
Background: We recently identified the balance between the level of G protein coupled receptor kinase 2 (GRK2) and Epac1 in nociceptors as a key factor in the transition from acute to chronic pain that occurs in mice ‘primed’ by an inflammatory stimulus.

Protein kinase C ζ interacts with a novel binding region of Gαq to act as a functional effector [PDF]
Heterotrimeric G proteins play an essential role in the initiation of G protein-coupled receptor (GPCR) signaling through specific interactions with a variety of cellular effectors.

Estrogen modulates β‐AR signaling in a context‐dependent manner influenced by species, sex, age, tissue, and vascular health, highlighting challenges in translating findings from experimental models to human cardiovascular physiology. ABSTRACT Cardiovascular diseases remain the leading global cause of morbidity and mortality, with notable sex‐specific ...

GRK2 suppresses lymphomagenesis by inhibiting the MALT1 proto-oncoprotein [PDF]
Antigen receptor-dependent (AgR-dependent) stimulation of the NF-κB transcription factor in lymphocytes is a required event during adaptive immune response, but dysregulated activation of this signaling pathway can lead to lymphoma. AgR stimulation promotes assembly of the CARMA1-BCL10-MALT1 complex, wherein MALT1 acts as (a) a scaffold to recruit ...

G protein coupled receptor (GPCR) kinases (GRKs) are key regulators of GPCR signaling. Canonical mechanism of GPCR desensitization involves receptor phosphorylation by GRKs followed by arrestin recruitment and uncoupling from heterotrimeric G protein ...
