a Docked pose of PGE2 within hEP4 with key residues shown. b Docked pose of PGE2 within rEP4 with key residues shown. c Overlay of PGE2 docked into rEP4 RaptorX model (orange) aligned with PGE2 docked into hEP4 (teal). PGE2 is displayed as sticks, EP4 models are displayed as cartoons with key residues shown as line representations. The two poses align closely despite differences in predicted interactions
