The G-protein-coupled receptor phosphatase: a protein phosphatase type 2A with a distinct subcellular distribution and substrate specificity.
(Proc Natl Acad Sci U S A, 1995-08-29)
Phosphorylation of G-protein-coupled receptors plays an important role in regulating their function. In this study the G-protein-coupled receptor phosphatase (GRP) capable of dephosphorylating G-protein-coupled receptor ...
Anti-beta(1)-adrenergic receptor antibodies and heart failure: causation, not just correlation.
(J Clin Invest, 2004-05)
Antibodies specific for the beta(1)-adrenergic receptor are found in patients with chronic heart failure of various etiologies. From work presented in this issue of the JCI, we can now infer that these antibodies actually ...
Beta-arrestin-mediated beta1-adrenergic receptor transactivation of the EGFR confers cardioprotection.
(J Clin Invest, 2007-09)
Deleterious effects on the heart from chronic stimulation of beta-adrenergic receptors (betaARs), members of the 7 transmembrane receptor family, have classically been shown to result from Gs-dependent adenylyl ...
Coupling of beta2-adrenoceptor to Gi proteins and its physiological relevance in murine cardiac myocytes.
(Circ Res, 1999-01-08)
-Transgenic mouse models have been developed to manipulate beta-adrenergic receptor (betaAR) signal transduction. Although several of these models have altered betaAR subtypes, the specific functional sequelae of betaAR ...
Mitogenic signaling via G protein-coupled receptors.
(Endocr Rev, 1996-12)
Independent beta-arrestin 2 and G protein-mediated pathways for angiotensin II activation of extracellular signal-regulated kinases 1 and 2.
(Proc Natl Acad Sci U S A, 2003-09-16)
Stimulation of a mutant angiotensin type 1A receptor (DRY/AAY) with angiotensin II (Ang II) or of a wild-type receptor with an Ang II analog ([sarcosine1,Ile4,Ile8]Ang II) fails to activate classical heterotrimeric G protein ...
Potentiation of beta-adrenergic signaling by adenoviral-mediated gene transfer in adult rabbit ventricular myocytes.
(J Clin Invest, 1997-01-15)
Our laboratory has been testing the hypothesis that genetic modulation of the beta-adrenergic signaling cascade can enhance cardiac function. We have previously shown that transgenic mice with cardiac overexpression of either ...
A magnificent time with the "magnificent seven" transmembrane spanning receptors.
(Circ Res, 2003-03-07)
The third beta is not the charm.
(J Clin Invest, 1996-07-15)
Expression of a beta-adrenergic receptor kinase 1 inhibitor prevents the development of myocardial failure in gene-targeted mice.
(Proc Natl Acad Sci U S A, 1998-06-09)
Heart failure is accompanied by severely impaired beta-adrenergic receptor (betaAR) function, which includes loss of betaAR density and functional uncoupling of remaining receptors. An important mechanism for the ...
