    N-terminal 10xHis-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：
    Lyophilized from Tris/PBS-based buffer, 6% Trehalose, pH 8.0

靶點詳情

  • 功能：
    Highly selective inward-rectifying potassium channel. This voltage-gated 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. Also permeable to ammonium ions. Blocked by tetraethylammonium and barium ions.
  • 基因功能參考文獻：
    1. Data show that in KAT-type K(+) channel KAT1, residue K85 within the linker forms a hydrogen bond with C211 that enables the pH activation. PMID: 26846460
    2. Plant stress metabolite acrolein inhibits light-induced stomatal opening through inhibition of KAT1 potassium channels in Arabidopsis thaliana. PMID: 25144495
    3. Mutations of the central Phe residue favored the closed KAT1 channel, whereas mutations affecting the countercharge centers favored the open channel PMID: 25185120
    4. instead of single key amino acids, several titratable residues contribute to the pH-sensor of the plant Kin channel KAT1 PMID: 22070190
    5. trafficking of KAT1 has been shown to depend on ER export signals PMID: 20712625
    6. Results indicate that, in plant cells, a kinase analogous to protein kinase C might exist that may modulate KAT1 channel activity through calcium-dependent phosphorylation at some of the pinpointed residues in the cytosolic region of KAT1. PMID: 20423459
    7. Phosphatidylinositol phosphates were identified as essential regulators for the voltage-dependent and -independent activation of A. thaliana potassium channels expressed in X. laevis oocytes. [KAT1] PMID: 15842627
    8. KAT1 was expressed in mammalian HEK293 cells and measured with patch clamp technology in the whole cell configuration. The data show that a depletion of extracellular potassium results in a decrease in channel conductance. PMID: 16263909
    9. This study demonstrated trafficking of plant plasma membrane ion channels is controlled via a conserved mechanism. PMID: 16950859
    10. Structure prediction for the down state of the Kat1 voltage sensor PMID: 17187053
    11. Study reports that the hormone abscisic acid, which controls ion transport and transpiration in plants under water stress, triggers the selective endocytosis of the KAT1 K+ channel protein in epidermal and guard cells. PMID: 17683934
    12. The combination use of the selected detergents enabled the effective purification of functional KAT1 with affinity and gel-filtration chromatography. PMID: 18638455
