    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
  • 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：
    Lyophilized from Tris/PBS-based buffer, 6% Trehalose, pH 8.0
  • 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：
    Basically, we can dispatch the products out in 1-3 working days after receiving your orders. Delivery time may differ from different purchasing way or location, please kindly consult your local distributors for specific delivery time.
    Note: All of our proteins are default shipped with normal blue ice packs, if you request to ship with dry ice, please communicate with us in advance and extra fees will be charged.
  • 注意事项：
    Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

  • 功能：
    Required for entry into the host cell through presentation or delivery of SipC at the host cell plasma membrane. Along with SipC, is necessary for the transfer of other effector proteins into the host cell. Induces macrophage apoptosis either by binding and activating the proapoptotic enzyme caspase-1 (caspase-1 dependent), resulting in the release of interleukin-1 beta active form, or by disrupting mitochondria and inducing autophagy (caspase-1 independent). The former is dependent of its membrane-fusion activity. The SipBC complex, in association with its chaperone SicA, is regulated by binding of InvE.
  • 基因功能参考文献：
    1. The results showed that the SipB does not affect the growth of Salmonella, but the adherence, invasion, and virulence of the mutant were significantly decreased compared with wild-type Salmonella Typhimurium SL1344. PMID: 26341924
    2. these findings provide the first evidence that the Salmonella virulence translocon SipB affects membrane fluidity and alters bacterial osmotolerance. PMID: 22975346
    3. These newly identified domains are composed of extended-length (114 A in IpaB and 71 A in SipB) coiled-coil motifs that display a high degree of structural homology to one another despite the fact that they share only 21% sequence identity. PMID: 22321794
    4. SipB translocon component binds cholesterol with high affinity, cholesterol-dependent association of the translocon with the target cell plasma membrane is essential for translocon activation and effector delivery into mammalian cells PMID: 15819617
    5. Residues 3-8 of the SipB protein are essential for its secretion from the bacterial cell and that the SicA chaperone binds to SipB somewhere between amino acids 80 and 100 of the SipB N-terminal region. PMID: 17768243
