Characterization of a new WHIM syndrome mutant reveals mechanistic differences in regulation of the chemokine receptor gain-of-function mutations that lead to C-terminal truncations, frame shifts and point mutations in the chemokine receptor Interestingly, there were also significant differences in receptor degradation, with S339fs5 having a

Angiotensin 1-7 (Ang-1-7), an endogenous peptide, acts at the G protein coupled MAS1 receptors (MASR)

current understanding on how endogenous PTHrP transduces signals through its cognate G-protein coupled receptor (GPCR), the PTH type 1 receptor (PTHR), is largely derived from studies done with its N-terminal fragment demonstrate using various fluorescence imaging approaches at the single cell level to measure kinetics of (i) receptor activation, (ii) receptor signaling via Gs and Gq, and (iii) receptor internalization and recycling

2022 GPCRs steer G i and G s selectivity via TM5-TM6 switches as revealed by structures of serotonin receptors hydroxytryptamine, 5-HT) is an important neurotransmitter that activates 12 different G protein-coupled receptors Here, we report the structures of the serotonin receptors 5-HT4, 5-HT6, and 5-HT7 with Gs, and 5-HT4 structures reveal that transmembrane helices TM5 and TM6 alternate lengths as a macro-switch to determine receptor's selectivity or promiscuity by class A GPCRs and extend the basis of ligand recognition at serotonin receptors

September 2022 "GPCR signaling and function depend on their associated proteins and subcellular locations. Besides G-proteins and β-arrestins, 14-3-3 proteins participate in GPCR trafficking and signaling, and they connect a large number of diverse proteins to form signaling networks. Multiple 14-3-3 isoforms exist, and a GPCR can differentially interact with different 14-3-3 isoforms in response to agonist treatment. 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 adaptor complexes during endocytosis. The temporal signals could implicate either GPCR/14-3-3 complex dissociation or the complex undergoing a degradation process. Furthermore, we found that certain GPCR ligands can regulate GPCR/14-3-3 signals temporally, suggesting a new approach for GPCR drug development by modulating GPCR/14-3-3 signals temporally."

Recurrent high-impact mutations at cognate structural positions in class A G protein-coupled receptors expressed in tumors G protein-coupled receptors (GPCRs) are the largest family of human proteins.
