Note: The complete sequence may include tag sequence, target protein sequence, linker sequence and extra sequence that is translated with the protein sequence for the purpose(s) of secretion, stability, solubility, etc.
If the exact amino acid sequence of this recombinant protein is critical to your application, please explicitly request the full and complete sequence of this protein before ordering.
蛋白標(biāo)簽：

C-terminal 6xHis-tagged
產(chǎn)品提供形式：

Liquid or Lyophilized powder
Note: We will preferentially ship the format that we have in stock, however, if you have any special requirement for the format, please remark your requirement when placing the order, we will prepare according to your demand.
緩沖液：

If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol. If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose.
復(fù)溶：

We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20℃/-80℃. Our default final concentration of glycerol is 50%. Customers could use it as reference.
儲存條件：

Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw cycles.
保質(zhì)期：

The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself.
Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C.
貨期：

3-7 business days
注意事項(xiàng)：

Repeated freezing and thawing is not recommended. Store working aliquots at 4℃ for up to one week.

功能：

Putative taste receptor. TAS1R2/TAS1R3 recognizes diverse natural and synthetic sweeteners.
基因功能參考文獻(xiàn)：
1. genetic association studies in population of preschool-aged children in Guelph, Ontario: Data suggest that SNPs in CD36 (rs1761667), TAS1R2 (rs35874116), and TAS2R38 (rs713598) are associated with snacking behavior in the population studied. [PILOT PROJECTS] PMID: 29385734
2. We observe that binding of agonists to VFD2 of TAS1R2 leads to major conformational changes to form a TM6/TM6 interface between TMDs of TAS1R2 and TAS1R3, which is consistent with the activation process observed biophysically on the metabotropic glutamate receptor 2 homodimer. PMID: 28228527
3. Alleles from each TAS1R2 locus (GG compared with AA alleles of rs12033832, and CT/CC compared with TT alleles of rs35874116) were related to higher consumption of carbohydrates (% energy) and higher amount of sweet foods, respectively (P<0.05). PMID: 29110749
4. The molecular anatomy of sweet taste receptor dimers T1R2-T1R3 has been presented. PMID: 27936499
5. no significant associations between GLUT2 and/or TAS1R2 polymorphisms and fillings were found, but allele frequencies of the TAS1R2 variant were marginally significantly different between children with DMFT = 0 and DMFT >/=1. no significant interaction between both genes and risk of dental caries was found. GLUT2 and TASR1 polymorphisms may influence the risk of caries in the Czech population PMID: 26112465
6. In conclusion, the Val/Val genotype of TAS1R2 was associated with a higher carbohydrate intake and HTG. PMID: 26907331
7. high-risk caries experience (>8 caries) was found to be associated with TAS1R2 rs35874116 homozygous polymorphic genotype. PMID: 25924601
8. The rs12033832 single nucleotide polymorphism in TAS1R2 is associated with sucrose taste and sugar intake, but the effect differs depending on BMI PMID: 26279452
9. human and mouse membrane trafficking systems for sweet taste receptors T1r2 and T1r3 PMID: 25029362
10. effects of artificial sweeteners on adipose tissue may be largely independent of the classical sweet taste receptors, T1R2 and T1R3 PMID: 24068707
11. Interaction between brazzein and the amino terminal domain of the sweet receptor subunit T1R2 showed a stronger interaction at 7 degrees C than at 37 degrees C.; the low temperature conformation, alters the orientations of 2 loops known to be critical for the sweetness of brazzein, may represent the bound state of brazzei in the complex with the human sweet receptor. PMID: 23349025
12. associated with caries risk PMID: 23257979
13. Genetic ablation of the sweet TR protein T1R2 obliterates fructose-induced insulin release and its potentiating effects on glucose-stimulated insulin secretion in vitro and in vivo. PMID: 22315413
14. T1R2/T1R3 is involved in glucose-dependent secretion of satiation peptides PMID: 21540445
15. Our findings show that a genetic variation in TAS1R2 affects habitual consumption of sugars and may contribute to interindividual differences in changing behaviors in response to dietary counseling. PMID: 20943793
16. significant associations were seen in TAS1R2 for caries risk and/or protection. PMID: 20858777
17. Data show that Positive allosteric modulators of the sweet taste receptor could help reduce the caloric content in food and beverages while maintaining the desired taste. PMID: 20173092
18. Results from mutagenesis and chimeras of the receptor indicated that brazzein interacts with both T1R2 and T1R3 and that the Venus flytrap module of T1R2 is important for brazzein agonism. PMID: 20302879
19. Interactions between the human sweet-sensing T1R2-T1R3 receptor and sweeteners detected by saturation transfer difference NMR spectroscopy. PMID: 19664591
20. The mechanism of interaction of the sweet protein monellin with the T1R2-T1R3 receptor. PMID: 12706725
21. sweet and umami taste are strictly dependent on T1R-receptors, and show that selective elimination of T1R-subunits differentially abolishes detection and perception of these two taste modalities PMID: 14636554
22. water rinses remove the inhibitor from the heteromeric sweetener receptor TAS1R2-TAS1R3, which activates cells and results in the perception of strong sweetness from pure water PMID: 16633339
23. Some of the amino acid positions crucial for activation of hTAS1R2+hTAS1R3 by neohesperidin dihydrochalcone are involved in the binding of allosteric modulators in other class C GPCRs PMID: 17935609
