Researchers Uncover Molecular Mechanisms of Lipid and Ligand Regulation in Prostaglandin Receptor DP2
A research team led by Eric H. Xu and WU Canrong from the Shanghai Institute of Materia Medica presented cryo-electron microscopy structures of apo DP2-Gi complex, a DP2-Gi complex bound to endogenous ligand PGD2, and a DP2-Gi complex bound to indomethacin, a ligand known to favor β-arrestin signaling. These structures revealed distinct binding modes and provided critical insights into the receptor's activation and signaling bias, highlighting the role of lipid interactions.
