T1R2/T1R3 dimer is a sweet taste receptor

A dimer of T1R2 and T1R3 receptors responds to diverse stimuli associated with the human sense of sweet taste, such as sucrose, d-tryptophan, aspartame, and saccharin. Signaling occurs via the Gi family G-protein Gustducin (Caicedo et al. 2003).T1R2和T1R3受体二聚体对与人类甜味感觉相关的一系列刺激作出反应，如蔗糖、D-色氨酸、阿斯巴甜和糖精。信号通过Gi家族G蛋白Gustducin（Caicedo等，2003年）进行传递。
