Citation | Journal: Nat Chem Biol / Year: 2023Title: The relaxin receptor RXFP1 signals through a mechanism of autoinhibition. Authors: Sarah C Erlandson / Shaun Rawson / James Osei-Owusu / Kelly P Brock / Xinyue Liu / Joao A Paulo / Julian Mintseris / Steven P Gygi / Debora S Marks / Xiaojing Cong / Andrew C Kruse / ![]() Abstract: The relaxin family peptide receptor 1 (RXFP1) is the receptor for relaxin-2, an important regulator of reproductive and cardiovascular physiology. RXFP1 is a multi-domain G protein-coupled receptor ...The relaxin family peptide receptor 1 (RXFP1) is the receptor for relaxin-2, an important regulator of reproductive and cardiovascular physiology. RXFP1 is a multi-domain G protein-coupled receptor (GPCR) with an ectodomain consisting of a low-density lipoprotein receptor class A (LDLa) module and leucine-rich repeats. The mechanism of RXFP1 signal transduction is clearly distinct from that of other GPCRs, but remains very poorly understood. In the present study, we determine the cryo-electron microscopy structure of active-state human RXFP1, bound to a single-chain version of the endogenous agonist relaxin-2 and the heterotrimeric G protein. Evolutionary coupling analysis and structure-guided functional experiments reveal that RXFP1 signals through a mechanism of autoinhibition. Our results explain how an unusual GPCR family functions, providing a path to rational drug development targeting the relaxin receptors. | |||||||||
