Two families of candidate taste receptors in zebrafish, T1Rs and T2Rs, show significant identity to mammalian T1Rs and T2Rs, respectively.
Genetic variants in TAS1R were associated with dietary consumption, which may be associated with gastric cancer risk
The study provides human psychophysical evidence that TAS1R1 polymorphisms associate with modest differences in overall taste intensity, which were independent from other well-studied markers of variation in oral sensation.
A complex molecular mechanism involving changes in the properties of both the orthosteric and non-orthosteric sites of T1R1 underlies the determination of ligand specificity in mammalian T1R1/T1R3.
Data show that that Tas1r1 and Tas1r3 are expressed in murine and human spermatozoa.
amino acid substitutions (A110V and R507Q) in the N-terminal ligand-binding domain of T1R1 severely impair receptor functions in vitro
sequence differences in T1R receptors within and between species (human and mouse) can significantly influence the selectivity and specificity of taste responses
findings demonstrate the different functional roles of T1R3 and T1R2 and the presence of multiple ligand binding sites on the sweet taste receptor
In vivo taste bud signaling may proceed primarily through hT1R1 and hT1R2.
human duodenal L cells express sweet taste receptor T1r.
Taken together, these results suggest that Tas1R1-Tas1R3 receptor variants found in human fungiform papillae might contribute to inter-individual differences of sensitivity to L-glutamate.
In our sample of subjects, the frequencies of 2 nsSNPs, C329T in tas1r1 and C2269T in tas1r3, were significantly higher in [glutamate] nontasters than expected, whereas G1114A in tas1r1 was more frequent in tasters.
residual sensitivity by the T1R1+T1R3 KO mice demonstrates that a T1R-independent mechanism can contribute to the detectability of high concentrations of this prototypical umami compound stimulus
T1R1/T1R3 modulates the mTOR pathway to regulate milk protein synthesis in the mouse mammary gland in vivo.
siRNA silencing of T1R1 repressed beta-casein synthesis in HC11 cells both with and without essential amino acids present in the culture medium. T1R1/T1R3 serves as sensor of extracellular amino acids in mouse mammary epithelial cells and involved in milk protein synthesis regulation.
T1R1/T1R3 have roles in regulating ERK1/2 and mTORC1 in MIN6 cells
Involvement of multiple taste receptors in umami taste: analysis of gustatory nerve responses in metabotropic glutamate receptor 4 knockout mice
This study demonstrated that that genetic transsynaptic tracing from bitter and umami receptor cells does not selectively label taste-specific neuronal circuits and reveal local taste receptor gene expression in the gustatory ganglia and the brain.
cell surface G protein coupled receptor (GPCR) TAS1R1-TAS1R3 (T1R1-T1R3) can sense extracellular amino acids, activate MTORC1, and inhibit autophagy
examined the function of umami taste receptor, which has a dimeric protein structure composed of Tas1r1 and Tas1r3, as an amino acid sensor
Data sugget that heterodimer of Tas1R1 and Tas1R3 is the fundamental receptor for the sensing amino acids and regulates the amino acid-induced insulin secretion in pancreatic beta-cells.
T1R1 and T1R3 combine to function as a broadly tuned L-amino-acid sensor responding to most of the 20 standard amino acids, but not to their D-enantiomers or other compounds
behavioral and physiological characterization of T1R1, T1R2, and T1R3 knockout mice
These results suggested that in fungiform papillae, gustducin might play a role in the sweet taste signal transduction cascade mediated by a sweet receptor based on the T1r2 and T1r3 combination, in fungiform papillae.
The protein encoded by this gene is a G protein-coupled receptor and is a component of the heterodimeric amino acid taste receptor T1R1+3. The T1R1+3 receptor responds to L-amino acids but not to D-enantiomers or other compounds. Most amino acids that are perceived as sweet activate T1R1+3, and this activation is strictly dependent on an intact T1R1+3 heterodimer. Multiple transcript variants encoding different isoforms have been found for this gene.
