BackgroundInsulin resistance is a metabolic disorder that occurs in type 2 diabetes mellitus and obesity. Genetic factors such as β3-adrenoceptor polymorphism (Trp64Arg) may be involved in IR and insulin secretion.

Nitric oxide-dependent activation of CaMKII increases diastolic sarcoplasmic reticulum calcium release in cardiac myocytes in response to adrenergic stimulation. [PDF]
Spontaneous calcium waves in cardiac myocytes are caused by diastolic sarcoplasmic reticulum release (SR Ca(2+) leak) through ryanodine receptors.

The beta-adrenergic receptor kinase (beta ARK) specifically phosphorylates the agonist-occupied form of the beta-adrenergic and related G protein-coupled receptors. Structural features of this enzyme have been elucidated recently by the isolation of a cDNA that encodes bovine beta ARK.

Glycyrrhetic acid synergistically enhances β₂-adrenergic receptor-Gs signaling by changing the location of Gαs in lipid rafts. [PDF]
Glycyrrhetic acid (GA) exerts synergistic anti-asthmatic effects via a β₂-adrenergic receptor (β₂AR)-mediated pathway. Cholesterol is an important component of the structure and function of lipid rafts, which play critical roles in the β₂AR-Gs-adenylate ...

Desensitization of the beta-adrenergic receptor, a receptor which is coupled to the stimulation of adenylate cyclase, may be regulated via phosphorylation by a unique protein kinase. This recently discovered enzyme, known as the beta-adrenergic receptor kinase, only phosphorylates the agonist-occupied form of the beta-adrenergic receptor.

The octopamine receptor Octβ2R regulates ovulation in Drosophila melanogaster.
Oviposition is induced upon mating in most insects. Ovulation is a primary step in oviposition, representing an important target to control insect pests and vectors, but limited information is available on the underlying mechanism.

Phosphorylation and Activation of β-Adrenergic Receptor Kinase by Protein Kinase C [PDF]
The aim of this study was to test the possible modification of beta-adrenergic receptor kinase (beta ARK) activity by second messengers and/or their downstream components. Using human mononuclear leukocytes (MNL), we found that calcium ionophores could elevate beta ARK activity by about 80% in a protein kinase C (PKC)-dependent manner.
