Inhibition of the beta-adrenergic receptor kinase by polyanions.
The beta-adrenergic receptor kinase, which specifically phosphorylates the agonist-occupied beta-adrenergic receptor, is strongly inhibited by polyanions. Heparin and dextran sulfate inhibit the enzyme with an IC50 of approximately 0.15 microM. De-N-sulfated heparin is approximately 8-fold less potent.

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 ...

Purification and characterization of the beta-adrenergic receptor kinase.
The beta-adrenergic receptor kinase (beta-ARK) is a recently discovered enzyme which specifically phosphorylates the agonist-occupied form of the beta-adrenergic receptor (beta-AR) as well as the light-bleached form of rhodopsin. beta-ARK is present in a wide variety of mammalian tissues.

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.

Regulation of Neuromodulator Receptor Efficacy - Implications for Whole-Neuron and Synaptic Plasticity [PDF]
Membrane receptors for neuromodulators (NM) are highly regulated in their distribution and efficacy - a phenomenon which influences the individual cell's response to central signals of NM release.

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.

Functional selectivity of GPCR-directed drug action through location bias. [PDF]
G-protein-coupled receptors (GPCRs) are increasingly recognized to operate from intracellular membranes as well as the plasma membrane. The β 2 -adrenergic GPCR can activate G s -linked cyclic AMP (G s -cAMP) signaling from endosomes.
