Non-Equilibrium Snapshots of Ligand Efficacy at the μ-Opioid Receptor

Michael J. Robertson, Arnab Modak, Makaía M. Papasergi-Scott…·Georgios Skiniotis

The paper uses cryo-EM to capture non-equilibrium states of the μ-opioid receptor bound to different ligands, revealing ligand-dependent conformational dynamics and G-protein activation differences.
