    Note: The complete sequence including tag sequence, target protein sequence and linker sequence could be provided upon request.
  • 蛋白标签：
    N-terminal 10xHis-tagged and C-terminal Myc-tagged
  • 产品提供形式：
    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.
  • 缓冲液：
    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.
  • 复溶：
    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.
  • 储存条件：
    Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw cycles.
  • 保质期：
    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.
  • 货期：
    3-7 business days
  • 注意事项：
    Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.
  • Datasheet & COA：

daf-7 Proteins

靶点详情

  • 功能：
    Under harsh environmental conditions, larvae enter a developmentally arrested state known as dauer; TGF-beta-like daf-7 acts to inhibit dauer larva formation and promote growth. May be a ligand to cell surface receptor daf-4. May act as a negative regulator of dauer larva development by transducing chemosensory information from ASI neurons. Involved in sensitivity to CO2 levels. In AWC neurons, acts to promote expression of srsx-3, a member of the GPCR family.
  • 基因功能参考文献：
    1. DAF-7 expression decreases as animals age during adulthood. Age-dependent diminished expression contributes to the reduced sensitivity of aging animals to the effects of dietary restriction. PMID: 28107363
    2. Using functional, fluorescently-tagged protein, we find that, in animals with mutant DAF-28/IGF, the wild-type DAF-7/TGF-beta is mislocalized to and accumulates in the proximal axon of the ASI neuron. Activation of two different branches of the unfolded protein response can modulate both the developmental phenotype and DAF-7 mislocalization in DAF-28(R37C) animals, but appear to act through divergent mechanisms PMID: 27926939
    3. GLR-1 protein and glr-1 transcription are increased in neurons of DAF-7 mutants. PMID: 26054666
    4. daf-7 has a role in larval development and specifically affects molting and excretory canal development PMID: 23526825
    5. We show that aggregation and bordering are genetically complex, with multiple contributing quantitative trait loci (QTLs), and refine one QTL to identify a new gene affecting the daf-7 pathway, the GABA receptor EXP-1. PMID: 23284308
