    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：
    N-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, pH 8.0.
  • 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(chǔ)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：
    Delivery time may differ from different purchasing way or location, please kindly consult your local distributors for specific delivery time.
  • 注意事項(xiàng)：
    Repeated freezing and thawing is not recommended. Store working aliquots at 4℃ for up to one week.
  • Datasheet & COA：

靶點(diǎn)詳情

  • 功能：
    Gustatory receptor which mediates acceptance or avoidance behavior, depending on its substrates. Gr43a is the main sugar receptor in larvae. Functions as a narrowly tuned fructose receptor in taste neurons but also as a fructose receptor in the brain. Necessary and sufficient to sense hemolymph fructose and promote feeding in hungry flies but suppress feeding in satiated flies.
  • 基因功能參考文獻(xiàn)：
    1. Here we sought to decipher the genes required for fructose response among Gr64a-Gr64f genes. Unexpectedly, the qPCR analyses for these genes show that labellar expression levels of Gr64d and Gr64e are higher in fructose low-sensitivity flies than in high-sensitivity flies PMID: 29047261
    2. Gr43a is the main receptor for larval sugar preference.Late sugars preference is mediated by Gr43a-expressing brain neurons. PMID: 23850280
    3. Studies indicate that the Gr43a-expressing brain neurons function as a nutrient sensor for hemolymph fructose and assign opposing valence to feeding experiences in a satiation-dependent manner. PMID: 23178127
  • 亞細(xì)胞定位：
    Cell membrane; Multi-pass membrane protein.
  • 蛋白家族：
    Insect chemoreceptor superfamily, Gustatory receptor (GR) family, Gr21a subfamily
  • 組織特異性：
    Expressed in the adult labellar chemosensory neurons and in the adult head, abdomen, leg and wing. In larvae, is expressed in taste organs, as well as the brain and the gastrointestinal system.
