The taste receptor type I (Tas1R) family consists of three G protein-coupled receptors (T1R1, T1R2, and T1R3) that form heterodimers recognizing sweet compounds (T1R2/T1R3) or amino acids (T1R1/T1R3). These receptors are nutrient sensors that facilitate appropriate physiological responses with nutrient availability. However, their contribution to the development of pathologies associated with overnutrition (e.
