Ligand-dependent G protein dynamics underlying opioid efficacy

Activation of heterotrimeric G proteins by G-protein-coupled receptors (GPCRs) requires large-scale opening of the Gα α-helical domain (AHD) to expose the nucleotide-binding site and facilitate GDP–GTP exchange. Although orthosteric ligands are known to modulate GPCR conformation, how these effects propagate to the bou...

Discovery of a Cell-Permeable Gi-Signaling Inhibitor

N-hydroxyapiosporamide (NHAP) is established as a first-in-class Gi-selective inhibitor, providing a cell-permeable chemical scaffold for the optimization of next-generation agents to control Gi-signaling in cell-based systems and, ultimately, to target Gαi1-driven pathologies.
