The human sweet taste receptor, a class C G protein-coupled receptor (GPCR) heterodimer composed of TAS1R2-TAS1R3, senses a wide range of sweet compounds - including natural sugars, artificial sweeteners and sweet proteins - impacting metabolic regulation beyond taste. However, the lack of three-dimensional structures hinders our understanding of its precise working mechanism. Here, we present cryo-EM 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 sweeteners recognition modes in TAS1R2. Structural comparisons further uncover the conformational changes upon ligand binding and unique activation mechanism. These findings illuminate the signal transduction mechanisms of chemosensory receptors in class C GPCRs and provide molecular basis for new-generation sweetener design.
