T1R1

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.

T1R1 is essentially a recognition receptor for the nitrogen signal in the body, and it may recognize the umami substance through its amino group.In our experiments, we used this gene to express umami taste receptors in Saccharomyces cerevisiae.

Usage and Biology

Putative taste receptor. TAS1R1/TAS1R3 responds to the umami taste stimulus (the taste of monosodium glutamate). Sequence differences within and between species can significantly influence the selectivity and specificity of taste responses.We acquire it from synthesis company.
