    E. coli biotin ligase (BirA) is highly specific in covalently attaching biotin to the 15 amino acid AviTag peptide. This recombinant protein was biotinylated in vivo by AviTag-BirA technology, which method is BriA catalyzes amide linkage between the biotin and the specific lysine of the AviTag.

  • 功能：
    Receptor that may play a role in the perception of bitterness and is gustducin-linked. May play a role in sensing the chemical composition of the gastrointestinal content. The activity of this receptor may stimulate alpha gustducin, mediate PLC-beta-2 activation and lead to the gating of TRPM5.
  • 基因功能参考文献：
    1. bitter taste perception TAS2R38 diplotypes associated with vegetable consumption in participants enrolled in either an enhanced or a minimal nutrition counseling intervention, were examined. PMID: 29686110
    2. A QPCR analysis demonstrated that TAS2R38, a subtype of the bitter taste receptor, was associated with GLP-1 secretion. Berberine-mediated GLP-1 secretion was attenuated in response to small interfering RNA silencing of TAS2R38. PMID: 29363059
    3. 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
    4. genetic association studies in population in Italy: Data suggest that an SNP in TAS2R38 (RS713598) is associated with higher bitter taste perception threshold and higher/lower preferences for selected nutrient/energy dense foods, such as beer, butter, and cured meat; this SNP may be associated with overweight. PMID: 28738701
    5. The current study suggests that genetic variation in TAS2R38 and CA6 influences picky eating in preschoolers. PMID: 28858874
    6. this study demonstrated that a Bacillus cereus product(s) elicited an NO-mediated innate defense response in upper airway epithelium that seemed to be partially mediated by a T2R signaling pathway PMID: 28716170
    7. Findings suggest that TAS2R38 may be associated with the risk for gastric cancer in Koreans, although the TAS2R38 diplotype did not influence dietary intake. PMID: 27245112
    8. It is suggested that the risk and resistance of cancers is antagonistically controlled by the two TAS2R38 alleles, PAV and AVI, rather than by the AVI allele alone. PMID: 28552880
    9. In addition, we found signatures of ancient selective forces acting on different African TAS2R38 haplotypes. Collectively our results provide evidence for a relaxation of recent selective forces acting on this gene and a revised hypothesis for the origins of the present-day worldwide distribution of TAS2R38 haplotypes.
