Biochem/physiol Actions

CMPD101 is an active site-targeting, potent and subtype-selective G protein-coupled receptor kinase GRK2 & GRK3 inhibitor (human GRK2/3 IC50 = 54/32 nM with 3 μM ATP and tubulin dimer as substrate; bovine GRK2 IC50 = 290 nM with 0.5 mM ATP and bROS as substrate; no GRK1/5 inhibition at 125 μM). CMPD101 selectively inhibits GPR39 agonist-induced β-arrestin recruitment (by 94% at 10 μM against 30 μM GPR39-C3/50 μM ZnCl2), but not cAMP pathway desensitization in cultures and prevents β-arrestin2-biased D2R ligand UNC9994(1 μg/side bilateral local injection) from blocking NMDAR antagonist PCP (6 mg/kg i.p.)-induced locomotion (60%/12% blockage without/with 0.5 μg CMPD101 co-injection) in mice in vivo.

Activated Gq protein-coupled receptors (GqPCRs) can be desensitized by phosphorylation and β-arrestin binding. The kinetics and individual contributions of these two mechanisms to receptor desensitization have not been fully distinguished. Here, we describe the shut off of protease-activated receptor 2

Differential regulation of the μ-opioid receptor (MOP) has been linked to the development of opioid tolerance and dependence which both limit the clinical use of opioid analgesics. At a cellular level, MOP regulation occurs via receptor phosphorylation, desensitization, plasma membrane

GPR39, a G-protein-coupled receptor activated by zinc, reportedly activates multiple intracellular signaling pathways via Gs, Gq, G12/13, and β-arrestin, but little is known about downregulation of the receptor upon its activation. To our knowledge, this is the first report on

Molecular pharmacology, 80(2), 294-303 (2011-05-21)
G protein-coupled receptors (GPCRs) are key regulators of cell physiology and control processes ranging from glucose homeostasis to contractility of the heart. A major mechanism for the desensitization of activated GPCRs is their phosphorylation by GPCR kinases (GRKs). Overexpression of

Agonists of the nociceptin/orphanin FQ opioid peptide (NOP) receptor, a member of the opioid receptor family, are under active investigation as novel analgesics, but their modes of signaling are less well characterized than those of other members of the opioid
