Mechanism of GPR84 allosteric modulation at a helix 8-proximate site
This study elucidates the structural mechanism of Gi-biased allosteric modulation in the GPR84 receptor by identifying a novel helix 8-proximate binding site for the positive allosteric modulator PSB-16671, which stabilizes a specific receptor conformation to enhance macrophage phagocytosis while avoiding desensitization.
