Fig. 5From: Improved homology modeling of the human & rat EP4 prostanoid receptorsDocked pose of Sulprostone (orange) in stick representation overlaid within hEP4 receptor with versus docked pose within rat (teal). Sulprostone scored higher in human receptor and matches the pose of PGE2 within human receptor but fails to match this pose within rat receptor. Note interactions with S103(3.41) within human modelBack to article page
