However, PrRP and its analogs also activate the neuropeptide FF ...Prolactin-releasing peptide (PrRP) is an endogenous ligand for the PrRPR, whose activation has been linked to anti-obesity effects. However, PrRP and its analogs also activate the neuropeptide FF receptor 2 (NPFF2R), which is associated with adverse cardiovascular effects. Understanding how PrRP-related peptides differentially engage these two distinct receptors is critical for developing safer, more selective therapeutics. In this study, we present cryo-EM structures of the PrRP analog GUB08248 bound to PrRPR-Gα and NPFF2R-Gα at resolutions of 2.45 Å and 2.85 Å, respectively. These structures reveal a conserved ligand recognition mode across both receptors, while highlighting distinct receptor-specific interactions. The NPFF2R-Gα complex further uncovers key features of receptor activation and G protein coupling. Together, our results offer structural insights that could guide structure-based drug design strategies favoring PrRPR selectivity, thereby advancing the therapeutic potential of the PrRP-PrRPR axis for obesity treatment. | ||||||||||||||||||
