    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.
  • Datasheet & COA：

  • 功能：
    Highly selective inward-rectifying potassium channel. This voltage-dependent channel could mediate long-term potassium influx into guard cells leading to stomatal opening. Assuming opened or closed conformations in response to the voltage difference across the membrane, the channel is activated by hyperpolarization. The channel activity is enhanced upon external acidification.

    1. The Arabidopsis K(+) channel KAT1 complements in K(+)-limited medium the growth of the K(+) uptake defective Saccharomyces cerevisiae mutant strain CY162, while another K(+) channel, AKT2, does not. PMID: 28933647
    2. CPK13 reduces stomatal aperture through its inhibition of the guard cell-expressed KAT2 and KAT1 channels. PMID: 25037208
    3. The nine-amino acid stretch 312TVRAASEFA320 that composes the first C-linker alpha-helix located just below the pore is a crucial determinant of KAT2 channel activity. PMID: 24406792
    4. KAT2 contributes to the synthesis of substituted hydroxybenzoylcholines.KAT2 plays the primary role in benzoic acid synthesis. PMID: 24254312
    5. KAT2 was able to re-locate AtKC1 fused to GFP from endomembranes to the plasma membrane, indicating that heteromeric AtKC1-KAT2 channels are efficiently targeted to the plasma membrane. PMID: 21518051
    6. KAT2 may function downstream of an important WRKY transcription repressor WRKY40, which may link KAT2 with the ABA receptor ABAR/CHLH-mediated signaling. PMID: 21257607
