Citation | Journal: Nat Commun / Year: 2023Title: Structural basis of lysophosphatidylserine receptor GPR174 ligand recognition and activation. Authors: Jiale Liang / Asuka Inoue / Tatsuya Ikuta / Ruixue Xia / Na Wang / Kouki Kawakami / Zhenmei Xu / Yu Qian / Xinyan Zhu / Anqi Zhang / Changyou Guo / Zhiwei Huang / Yuanzheng He / ![]() Abstract: Lysophosphatidylserine (LysoPS) is a lipid mediator that induces multiple cellular responses through binding to GPR174. Here, we present the cryo-electron microscopy (cryo-EM) structure of LysoPS- ...Lysophosphatidylserine (LysoPS) is a lipid mediator that induces multiple cellular responses through binding to GPR174. Here, we present the cryo-electron microscopy (cryo-EM) structure of LysoPS-bound human GPR174 in complex with G protein. The structure reveals a ligand recognition mode, including the negatively charged head group of LysoPS forms extensive polar interactions with surrounding key residues of the ligand binding pocket, and the L-serine moiety buries deeply into a positive charged cavity in the pocket. In addition, the structure unveils a partially open pocket on transmembrane domain helix (TM) 4 and 5 for a lateral entry of ligand. Finally, the structure reveals a G engaging mode featured by a deep insertion of a helix 5 (αH5) and extensive polar interactions between receptor and αH5. Taken together, the information revealed by our structural study provides a framework for understanding LysoPS signaling and a rational basis for designing LysoPS receptor-targeting drugs. | |||||||||
