The mechanism by which relaxin activates the relaxin family peptide receptor-1 is poorly understood. Here, Sethi et al.identify a relaxin binding site in an extracellular linker between the LDLa and LRR domains and propose that relaxin binding stabilizes a helical conformation that leads to receptor activation.
