| + | CD97 (ADGRE5) is an adhesion G protein-coupled receptor (aGPCR) which plays crucial roles in immune system and cancer. However, the mechanism of CD97 activation and the determinant of G(13) coupling selectivity remain unknown. Here, we present the cryo-electron microscopy structures of human CD97 in complex with G(13), G(q), and G(s). Our structures reveal the stalk peptide recognition mode of CD97, adding missing information of the current tethered-peptide activation model of aGPCRs. For instance, a revised "FXphiphiphi" motif and a framework of conserved aromatic residues in the ligand-binding pocket. Importantly, structural comparisons of G(13), G(q), and G(s) engagements of CD97 reveal key determinants of G(13) coupling selectivity, where a deep insertion of the alpha helix 5 and a closer contact with the transmembrane helix 6, 5, and 3 dictate coupling preferences. Taken together, our structural study of CD97 provides a framework for understanding CD97 signaling and the G(13) coupling selectivity. | ||
