Our group has previously determined the crystal structure ...Prostaglandin receptors have been implicated in a wide range of functions, including inflammation, immune response, reproduction, and cancer. Our group has previously determined the crystal structure of the active-like EP3 bound to its endogenous agonist, prostaglandin E. Here, we present the single-particle cryoelectron microscopy (cryo-EM) structure of the human EP3-G signaling complex at a resolution of 3.4 Å. The structure reveals the binding mode of G to EP3 and the structural changes induced in EP3 by G binding. In addition, we compare the structure of the EP3-G complex with other subtypes of prostaglandin receptors (EP2 and EP4) bound to G that have been previously reported and examine the differences in amino acid composition at the receptor-G protein interface. Mutational analysis reveals that the selectivity of the G protein depends on specific amino acid residues in the second intracellular loop and TM5. | |||||||||||||||||||||
