Abstract
The present invention relates to the discovery that specific human taste receptors in the T2R taste receptor family respond to particular bitter compounds. Also, the invention relates to the discovery of specific hT2R9 alleles and their disparate activity in functional assays with the same biter ligands. The invention further relates to the use of these T2R receptors in assays for identifying ligands that modulate the activation of these taste receptors by specific bitter ligands and related compounds. These compounds may be used as additives and/or removed from foods, beverages, cosmetics and medicinals in order to modify (block) T2R-associated bitter taste. Also T2R ligands may be used as therapeutics to treat and modulate T2R associated gastrointestinal and metabolic functions as well as treat gastrointestinal and metabolic diseases such as eating disorders, food sensing, fod absorption, obesity, diabetes, Crohn's disease, celiac disease, et al.
