    The tag type will be determined during production process. If you have specified tag type, please tell us and we will develop the specified tag preferentially.
  • 產(chǎn)品提供形式：
    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.
  • 復(fù)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(chǔ)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.
    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.
  • 注意事項(xiàng)：
    Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

靶點(diǎn)詳情

  • 功能：
    Regulatory subunit of Kv4/D (Shal)-type voltage-gated rapidly inactivating A-type potassium channels. Modulates channel density, inactivation kinetics and rate of recovery from inactivation in a calcium-dependent and isoform-specific manner. In vitro, modulates KCND2/Kv4.2 and KCND3/Kv4.3 currents. Involved in KCND2 and KCND3 trafficking to the cell surface. May be required for the expression of I(To) currents in the heart.
  • 基因功能參考文獻(xiàn)：
    1. although there is a baseline presence of KChIP2 in the nucleus both in vivo and in vitro, KChIP2 does not directly regulate transcriptional activity. Moreover, the nuclear transport of KChIP2 is not dependent on Ca(2+). Thus, KChIP2 does not function as a conventional transcription factor in the heart. PMID: 27349185
    2. Our results do not support the notion that accessory KChIP2 binding is a prerequisite for dendritic trafficking and functional surface expression of Kv4.2 channels, however, accessory KChIP2 binding may play a potential role in Kv4.2 modulation during intrinsic plasticity processes. PMID: 29385176
    3. Results identify the KChIP2/miR-34 axis as a central regulator in developing cardiac electrical dysfunction. PMID: 28263709
    4. A novel KCNQ1-G229D mutation identified in a juvenile-onset AF patient altered the IKs activity and kinetics, thereby increasing the arrhythmogenicity to AF. PMID: 24096004
    5. mutations cause a gainoffunction of KV4.3/KChIP2encoded channels by increasing membrane protein expression and slowing channel inactivation. PMID: 26016905
    6. The "structurally minimal" isoform KChIP2d modulates recovery of K(v)4.3 N-terminal deletion mutant Delta2-39. PMID: 21422811
    7. KChIP2 differentially regulates total and cell surface Kv4.2 protein expression and Kv4 current densities. PMID: 20709747
    8. The I(to) activator NS5806 modified Kv4.3/KChIP2 gating in several ways that inhibit current. PMID: 20649599
    9. The cytoplasmic accessory subunit KChIP2 also assembles with Kv4.2 to increase peak current, shift V1/2 ~5mV, slow time to peak ~10%, slow inactivation ~100%, and speed recovery from inactivation ~250% without overshoot. PMID: 20498229
    10. N-linked glycosylation of DPP10 plays an important role in modulating Kv4.3 channel/KCHIP2 complex activities. PMID: 20354865
    11. Down-regulated atrial KChIP2 and Kv4.3 mRNA expressions in rheumatic heart disease patients with chronic atrial fibrillation might be one of the molecular bases responsible for the down-regulation of the I(to) current density of AF. PMID: 19927631
    12. Regulation of Kv4.3 current by KChIP2 splice variants PMID: 12135940
    13. Kv4.2 and K+ channel-interacting protein 2 make up a complex of Ito channels PMID: 14623880
    14. Data show that KChIP1, KChIP2.1, and KChIP2.2 could form homo- as well as hetero-oligomers, and that this oligomerization did not perturb their interaction with Kv4.2 potassium channel. PMID: 15358149
    15. Both Kv4.3 and KChIP2 may contribute to epicardial-endocardial gradients in the transient outward current in normal and failing hearts. PMID: 15498806
    16. Co-expression of SGK1, but not of SGK2 or SGK3, increased Kv 4.3/KChIP2b channel currents. [KChIP2b; AH010566] PMID: 15578212
    17. KChIP-2 is a Ca2+-dependent repressor of the immune response. PMID: 16177826
    18. the C-terminal domain of Kv4.2 plays a critical role in voltage-dependent activation and functional expression that is mediated by direct interaction between the Kv4.2 C terminus and KChIP2 PMID: 16820361
    19. The conformational change with metal-bound KChIP4.1 is crucial for its interaction with Kv channel but not for KChIP2.2, and that the Mg2+- and Ca2+-binding properties of KChIP2.2 and KChIP4.1 have different effects on their molecular structure. PMID: 16951992
