引用 | ジャーナル: Nat Commun / 年: 2026タイトル: Mechanistic insight into signal bias by the agonist-dependent conformational dynamics of GPR84. 著者: Shota Suzuki / Duy Phuoc Tran / Kouki Nishikawa / Akio Kitao / Yoshinori Fujiyoshi / ![]() 要旨: GPR84 is an orphan class A GPCR primarily expressed in immune cells, where it plays key roles in inflammation and metabolism. Here, we present the cryo-electron microscopy structures of the GPR84-Gi ...GPR84 is an orphan class A GPCR primarily expressed in immune cells, where it plays key roles in inflammation and metabolism. Here, we present the cryo-electron microscopy structures of the GPR84-Gi complex bound to the G protein-biased agonist DL-175, and the inactive state of GPR84 bound to the antagonist GLPG1205. Combined with signaling assays and molecular dynamics simulations, these structures elucidate the conformational landscape spanning the inactive and G protein-biased active states of GPR84, providing a mechanistic basis for biased agonism. Notably, steric interactions between DL-175 and L336 selectively preclude the conformational changes required for efficient β-arrestin recruitment without compromising G protein activation. These structural insights provide a structural context for the rational design of GPR84-targeted therapeutics with precisely tuned signaling profiles. | |||||||||||||||
