G protein-coupled receptors (GPCRs) transduce extracellular signals into intracellular events. The waning responsiveness of GPCRs in the face of persistent agonist stimulation, or desensitization, is a necessary event that ensures physiological homeostasis. GPCR kinases (GRKs) are important regulators of GPCR desensitization. GRK5, one member of the GRK family, desensitizes central M(2) muscarinic receptors in mice. We questioned whether GRK5 might also be an important regulator of peripheral…

Desensitization of G protein-coupled receptors and neuronal functions.

An important and specific role of GRKs and beta arrestins in regulating physiological responsiveness to psychostimulants and morphine suggests potential involvement of these molecules in certain brain disorders, such as addiction, Parkinson's disease, mood disorders, and schizophrenia.

Physiological roles of G protein-coupled receptor kinases and arrestins.

This review focuses on the physiological functions and potential pathophysiological roles of GRKs and arrestins in human disorders as well as on recent studies using knockout and transgenic mice to explore the role ofGRK-arrestin regulation of GPCRs in vivo.

Atypical Actions of G Protein-Coupled Receptor Kinases

These newly discovered functions of GRKs are described, including roles in regulation of rhodopsin function and mediation of receptor-mediated cellular responses in a G proteinindependent manner.

One major outstanding question concerning GRKs understanding the mechanisms by which any particular receptor subtype is regulated by a specific GRK(s), and the consequences of this specificity could allow targeting of GRK function to ameliorate diseases involving GPCR dysregulation.

G Protein Coupled Receptor Kinases as Therapeutic Targets in Cardiovascular Disease

The role of GRKs in cardiovascular pathophysiology is reviewed, with an emphasis on the role of GPCR second-messenger cascades.

Targeted transgenesis reveals discrete attenuator functions of GRK and PKA in airway β2-adrenergic receptor physiologic signaling

These two mechanisms indeed impact a relevant β2AR physiologic function, acting as attenuators of the acute response, and represent specific interfaces where adjunct therapy or biased ligands may improve β-agonist treatment of obstructive lung disease.

G-Protein-Coupled Receptor Kinase 2 and Hypertension

This review attempts to assemble the currently available information concerning GRK2 and hypertension, opening new potential fields of translational investigation to treat this vexing disease.

Beta2-agonist and anticholinergic drugs in the treatment of lung disease.

The lungs are innervated by both the sympathetic and parasympathetic nervous systems, which entails the activation of adrenergic and muscarinic receptors, respectively, which must be considered in the design, development, and use of drugs to combat airway diseases.

Phosphorylation and regulation of a G protein–coupled receptor by protein kinase CK2

It is concluded that G protein–coupled receptors (GPCRs) can be phosphorylated in an agonist-dependent fashion by protein kinases from a diverse range of kinase families, not just the GPCR kinases, and that receptor phosphorylation by a defined kinase determines a specific signalling outcome.

Accelerating Alzheimer's pathogenesis by GRK5 deficiency via cholinergic dysfunction

The GRK5 deficiency appears to bring the two major hypotheses in Alzheimer’s disease together, whereas the GRK4 deficiency is the pivotal link, and any strategies that can break this cycle would be therapeutically beneficial for Alzheimer's patients.



Altered airway and cardiac responses in mice lacking G protein-coupled receptor kinase 3.

Data demonstrate that in the mouse, GRK3 may be involved in modulating the cholinergic response of airway smooth muscle and in regulating the chronotropic component of the baroreceptor reflex.

Monoclonal antibodies reveal receptor specificity among G-protein-coupled receptor kinases.

The generation of monoclonal antibodies that specifically react with GRK2 and GRK3 or withGRK4, GRK5, andGRK6 is described, which represents a novel approach to the study of receptor specificities among GRKs that should be widely applicable to many G-protein-coupled receptors.

It is determined that human embryonic kidney 293 cells express an endogenous VPAC1R that did demonstrate dose-dependent GRK specificity and agonist-stimulated, GRK-mediated phosphorylation, β-arrestin translocation, and dynamin-dependent receptor internalization.

Mechanism of cytokine-induced modulation of beta-adrenoceptor responsiveness in airway smooth muscle.

Observations provide new evidence demonstrating that IL-lbeta and TNF-alpha induce impaired receptor-coupled airway relaxation in naive TSM, and that the latter effect is associated with increased muscarinic M2-receptor/Gi protein- coupled expression and function.

There is increasing concern that regular ß2-adrenergic receptor agonist use in the therapy of asthma is deleterious, and evidence for dysfunction of the receptors on airway smooth muscle and inflammatory cells is unlikely to be of primary importance in the pathogenesis of asthma.

Mechanism of impaired beta-adrenoceptor responsiveness in atopic sensitized airway smooth muscle.

Observations provide new evidence that the impaired beta-adrenoceptor-mediated relaxation in atopic sensitized airways is associated with increased muscarinic M2 receptor/G(i) protein-coupled expression and function.

Direct activation of K(Ca) channel in airway smooth muscle by nitric oxide: involvement of a nitrothiosylation mechanism?

The data suggest that NO-induced bronchorelaxation occurs partly via a direct activation of KCa channels, possibly through a covalent interaction with the cytoplasmic side of their alpha subunit.
