The conformations of residues critical for receptor activation, e.g., E 3.49 R 3.50 Y 3.51 , N 7.49 P 7.50 xxY 7.53 , P 5.50 T 3.40 F 6.44 , and the toggle switch motifs, are conformationally similar between the structures of active CCKRs, suggesting a shared activation mechanism, despite that CCK1R and CCK2R exhibit different G protein-coupling profiles (Fig
