TAS1R1 (taste 1 receptor member 1) is a 7 transmembrane (7TM) receptor belonging to the family 3 (also known as family C) of the G-protein-coupled receptors (GPCRs). Structurally they are composed of 4 elements; an N-terminal signal peptide; a large hydrophilic extracellular agonist-binding region; a region containing 7TM domains; and a C-terminal cytoplasmic domain of variable length. Family 3 members include the metabotropic glutamate receptors (mGluRs), the extracellular calcium-sensing receptors (CASRs), the gamma-amino-butyric acid (GABA) type B receptors, and the vomeronasal type-2 receptors.  These GPCRs regulate many important physiological processes and many of them are promising targets for drug development.  TAS1R1 is a putative taste receptor. It is a component of the heterodimeric amino acid taste receptor consisting of TAS1R1 and TAS1R3. The receptor compex responds to the umami taste stimulus (the taste of monosodium glutamate). Most amino acids that are perceived as sweet activate the TAS1R1 and TAS1R3 complex and this activation is strictly dependent on an intact heterodimer of TAS1R1 and TAS1R3. Sequence differences within and between species can significantly influence the selectivity and specificity of taste responses.

Product Details

 

Gene Symbol: TAS1R1; TR1; T1R1; GM148; GPR70

 

NCBI Gene ID: 80835

 

Uniprot Entry: Q7RTX1

 

Construct Details: Full length human TAS1R1 gene is subcloned into the Lentiviral expression vector pLTC with an upstream CMV promoter and with or without a selection marker, which can be used for both transient and stable expression in mammalian cells.  It can be co-transfected with the LentiPAK DNA mix (SKU# LP-001) into HEK293 cells to produce high titer lentiviral particles. Multiple choices of a stable antibiotic selection marker are available.

 

Vector Type: pLTC or pLTC-IRES-Marker (lentiviral expression vector containing a heterologous CMV promoter +/- a selection marker, see the vector map above)

 

Formulation: Supplied with 10 μg of endotoxin-free plasmid DNA at 200 ng/μl in sterile TE buffer (pH8.0)

 

Gene Insert Size: 2526 (bp)

Primers: Gene insert coding sequence can be confirmed by following primers:

(a) forward (or 5'-end) primer: 5’-CAAATGGGCGGTAGGCGTG-3’;

(b) reverse (or 3'-end) primer: 5’-CCAGGTTTCCGGGCCCTCAC-3’

 

 

Note: The sequence may vary due to the naturally occurring variants or mutations, such as single nucleotide polymorphism, or the artifact during PCR amplification.  High fidelity PCR systems should always be used.
