The human sweet taste receptor, a class C G-protein-coupled receptor (GPCR) heterodimer composed of TAS1R2 and TAS1R3 (refs. ), senses a wide range of sweet compounds-including natural sugars, artificial sweeteners and sweet proteins-and affects metabolic regulation beyond taste. However, the lack of three-dimensional structures hinders our understanding of its precise working mechanism. Here we present cryo-electron microscopy structures of the full-length human sweet taste receptor in apo and sucralose-bound states. These structures reveal a distinct asymmetric heterodimer architecture, with sucralose binding exclusively to the Venus flytrap domain of TAS1R2. Combining mutagenesis and molecular dynamics simulations, this work delineates the sweetener-recognition modes in TAS1R2. Structural comparisons further uncover conformational changes upon ligand binding and a unique activation mechanism. These findings illuminate the signal transduction mechanisms of chemosensory receptors in the class C GPCR family and provide the molecular basis for the design of a new generation of sweeteners.
