    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：
    Delivery time may differ from different purchasing way or location, please kindly consult your local distributors for specific delivery time.
  • Datasheet & COA：

靶點詳情

  • 功能：
    Alpha-tubulin-specific protease that is required for entry into epithelial cells and for subsequent intra- and intercellular spreading. Contributes to bacterial entry into epithelial cells by inducing microtubule (MT) destabilization and the formation of membrane ruffles. The membrane ruffling evoked by VirA results from the activation of host rac1, which is associated with the destruction of MT networks. Creates a tunnel inside the host cell cytoplasm by breaking down the microtubule infrastructure. This facilitates the bacterium's movement through the cytoplasm and also helps other bacteria move faster during the invasion of the eukaryotic cell. Is absolutely required for virulence.
  • 基因功能參考文獻：
    1. Study discovers that bacterial effectors including VirA from nonvacuole Shigella flexneri and EspG from extracellular Enteropathogenic Escherichia coli (EPEC) harbor TBC-like dual-finger motifs and exhibits potent RabGAP activities. Specific inactivation of Rab1 by VirA/EspG disrupts ER-to-Golgi trafficking. PMID: 22939626
  • 亞細胞定位：
    Secreted. Note=Translocated into the host cell via the type III secretion system (TTSS). Localizes in the cytoplasm of the infected cell.
  • 蛋白家族：
    Protease EspG/VirA family
