Phosphorylation of chick heart muscarinic cholinergic receptors by the .beta.-adrenergic receptor kinase

Biochemistry, 1989
Previous studies have demonstrated that muscarinic cholinergic receptors (mAChR) become markedly phosphorylated when intact cardiac cells are stimulated with a muscarinic agonist. This process appears to be related to the process of receptor desensitization. However, the mechanism of agonist-induced phosphorylation of mAChR is not known.

The β-adrenergic receptor kinase in heart failure

Journal of Molecular and Cellular Cardiology, 2003
Heart failure (HF) remains a significant and increasing cause of worldwide morbidity and mortality. HF is less a disease than a common clinical endpoint resulting from diverse, but often co-existing etiologies-including hypertension, coronary artery disease, and viral cardiomyopathy.

Transgenic manipulation of beta-adrenergic receptor kinase modifies cardiac myocyte contraction to norepinephrine

American Journal of Physiology-Heart and Circulatory Physiology, 1997
To determine the direct functional significance of the beta-adrenergic receptor (AR) kinase 1 (beta ARK1) on myocardial performance in the absence of tonic sympathoadrenal neural activation and mechanical loading, we measured the contractile responses to acute beta 1-AR stimulation in left ventricular myocytes isolated from nontransgenic control (NTG)

Molecular Cloning, Functional Expression and mRNA Analysis of Human Beta-Adrenergic Receptor Kinase 2

Biochemical and Biophysical Research Communications, 1993
In the present study the cDNA of human beta ARK2 was cloned using both PCR and cDNA library screening, subcloned into an expression vector and transiently expressed in COS7 cells. The expressed kinase activity was approximately 40% as efficient as human beta ARK1 in phosphorylating bovine rod outer segments in vitro. Northern blot analysis of human and

Activation of β-Adrenergic Receptor Kinase During Myocardial Ischemia

Circulation Research, 1996
During myocardial ischemia, a local release of noradrenaline coincides with an increased density of β-adrenergic receptors. The functional activity of these receptors, however, is mainly determined by their state of phosphorylation. The β-adrenergic receptor kinase (βARK) specifically phosphorylates and thereby inactivates β-adrenergic receptors after ...

Serum creatine kinase release and alpha- and beta-adrenergic receptors.

Archives internationales de pharmacodynamie et de therapie, 1986
Changes in the serum creatine kinase (CK) activity and the mechanism of its release after administration of two kinds of beta-blockers to rats were studied in order to determine the mechanism of the increase in serum CK accompanying administration of beta-blockers.
