Authors: Geng Chen / Xiankun Wang / Qiwen Liao / Yunjun Ge / Haizhan Jiao / Qiang Chen / Yezhou Liu / Wenping Lyu / Lizhe Zhu / Gydo C P van Zundert / Michael J Robertson / Georgios Skiniotis / Yang ...Authors: Geng Chen / Xiankun Wang / Qiwen Liao / Yunjun Ge / Haizhan Jiao / Qiang Chen / Yezhou Liu / Wenping Lyu / Lizhe Zhu / Gydo C P van Zundert / Michael J Robertson / Georgios Skiniotis / Yang Du / Hongli Hu / Richard D Ye / ![]() ![]() Abstract: The formyl peptide receptor 1 (FPR1) is primarily responsible for detection of short peptides bearing N-formylated methionine (fMet) that are characteristic of protein synthesis in bacteria and ...The formyl peptide receptor 1 (FPR1) is primarily responsible for detection of short peptides bearing N-formylated methionine (fMet) that are characteristic of protein synthesis in bacteria and mitochondria. As a result, FPR1 is critical to phagocyte migration and activation in bacterial infection, tissue injury and inflammation. How FPR1 distinguishes between formyl peptides and non-formyl peptides remains elusive. Here we report cryo-EM structures of human FPR1-Gi protein complex bound to S. aureus-derived peptide fMet-Ile-Phe-Leu (fMIFL) and E. coli-derived peptide fMet-Leu-Phe (fMLF). Both structures of FPR1 adopt an active conformation and exhibit a binding pocket containing the R201XXXR205 (RGIIR) motif for formyl group interaction and receptor activation. This motif works together with D106 for hydrogen bond formation with the N-formyl group and with fMet, a model supported by MD simulation and functional assays of mutant receptors with key residues for recognition substituted by alanine. The cryo-EM model of agonist-bound FPR1 provides a structural basis for recognition of bacteria-derived chemotactic peptides with potential applications in developing FPR1-targeting agents. | ||||||
