internalization. β-Arrestins facilitate this process by interacting with adapter protein 2 (AP-2) and conformation-selective probes for monitoring activation-induced changes in cellular environments (Irannejad, R. In addition, the question of whether β-arrestin1 and 2 serve overlapping or distinct functions remains changes for the binding to the same GPCR to mediate differential regulatory effects (Haider, R. pathological conditions, including cancer (Gros, R. et al. 2000, Sun, W.

We found that some agonist-induced GPCR/14-3-3 signal intensities can rapidly decrease. We confirmed that this phenomenon of rapidly decreasing agonist-induced GPCR/14-3-3 signal intensity could also be paralleled with GPCR/β-arrestin-2 signals, indicating diminished levels of GPCR/signal Furthermore, we found that certain GPCR ligands can regulate GPCR/14-3-3 signals temporally, suggesting Read more at the source #DrGPCR #GPCR #IndustryNews

October 2022 "Protease-activated receptor 2 (PAR2) is a G-protein-coupled receptor (GPCR) activated by Once activated, PAR2 is rapidly desensitized and internalized by phosphorylation and β-arrestin recruitment by GB83, which may be the reason why GB83 is recognized as an antagonist of PAR2. Our results revealed that GB83 is a bona fide agonist of PAR2 that uniquely modulates PAR2-mediated cellular Read more at the source #DrGPCR #GPCR #IndustryNews

We synthesized and characterized a novel A2AAR antagonist, 2 (LJ-4517), with Ki = 18.3 nM. X-ray crystallographic structures of 2 in complex with two thermostabilized A2AAR constructs were solved The n-hexynyl group of 2 extends into an A2AAR exosite. Structural analysis revealed that the introduced thiophene modification restricted receptor conformational rearrangements required for subsequent activation.
