However, the effects of the C tail- and TM core-mediated interactions on the conformational activation Here, we show the conformational changes for βarr activation upon the C tail- and TM core-mediated interactions The conformation-selective antibody, Fab30, promotes partially activated βarr into the activated-like conformation. This plasticity of βarr conformation in complex with GPCRs engaged in different binding modes may explain

Nuclear magnetic resonance (NMR) spectroscopy allows the determination of atomic-level information on intermolecular interactions, molecular structure, and molecular dynamics in the cellular environment This may be broadly divided into studies focused on obtaining detailed molecular information in the intracellular affinities, competitive binding assays, delineation of ligands involved in binding, ligand bound-state conformational determination, evaluation of receptor structuring and dynamics, and inference of distance constraints

The localization of GPCRs to specific intracellular compartments dictates the spatial and temporal dynamics For example, the lipid composition of intracellular membranes may influence GPCR dynamics and signaling outcomes, changing the receptor conformation and accessibility to ligands2. Tagging molecules may alter the conformation or activity of GPCRs, leading to unintended effects on downstream

The physical barrier this lipid bilayer creates is dynamic and interactive, becoming the foundation for physical properties might impact ligand binding, receptor activation, G protein interactions, signaling dynamics Based on an ingenious combination of multicolor single-molecule microscopy approach with molecular dynamics with the lipid bilayer likely contributes to stabilizing β-arrestin in a membrane-bound, active-like conformation Membrane phosphoinositides regulate GPCR-β-arrestin complex assembly and dynamics.
