Structure of formylpeptide receptor 2-Gi complex reveals insights into ligand recognition and signaling

Abstract

Formylpeptide receptors (FPRs) are a class of chemotactic G protein-coupled receptors (GPCRs) that recognize pathogen- and host-derived formylpeptides. Here the authors report the 3.17 Å cryo-EM structure of the human FPR2-Gi signaling complex with a bound peptide agonist and in combination with computational docking and MD simulations provide mechanistic insights into formylpeptide recognition by FPRs.
