    Avi-tag Biotinylated

    E. coli biotin ligase (BirA) is highly specific in covalently attaching biotin to the 15 amino acid AviTag peptide. This recombinant protein was biotinylated in vivo by AviTag-BirA technology, which method is BriA catalyzes amide linkage between the biotin and the specific lysine of the AviTag.

  • 蛋白标签：
    Tag type will be determined during the manufacturing process.
    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.
  • 产品提供形式：
    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.
  • 复溶：
    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.
  • 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：
    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 ：

  • 功能：
    Ancillary protein that assembles as a beta subunit with a voltage-gated potassium channel complex of pore-forming alpha subunits. Modulates the gating kinetics and enhances stability of the channel complex. May associate with KCNQ1/KVLTQ1 and inhibit potassium current.
  • 基因功能参考文献：
    1. The KCNE1 (rs1805127) appears to an independent risk factor for AF in the Uygur population. And the KCNE4 (rs12621643) was an independent risk factor for AF among both Uygurs and Hans. PMID: 28981946
    2. the tertiary structure of the C-terminal domain of Kv1.3 is necessary and sufficient for Kv1.3- KCNE4 interaction. PMID: 27802162
    3. the association of the KCNE4 gene variability with allergic rhinitis PMID: 23866632
    4. KCNE4 juxtamembrane region is required for interaction with calmodulin and for functional suppression of KCNQ1. PMID: 21118809
    5. MiRP3 modulates Kv4.2 current activation, inactivation and recovery from inactivation. MiRP3 shifts the half-maximal voltage for activation and slows time to peak ~ 100%. PMID: 20498229
    6. KCNE4 E145D polymorphism may be related to atrial fibrillation. PMID: 16563243
    7. KCNE4 (potassium voltage-gated channel subfamily E member 4), but not KCNE2, functions as an inhibitory Kv1.3 partner in leukocytes. PMID: 19773357
    8. expressed strongly in heart, skeletal muscle, and kidney, less in placenta, lung, and liver, and weakly in brain and blood cells. Electrophysiological study showed that KCNE4 modulates the activation of the KCNQ1 channel. PMID: 12670483
    9. KCNE4 beta-subunit has a drastic inhibitory effect on currents generated by Kv1.1 and Kv1.3 potassium channels PMID: 12944270
    10. Based upon previous studies and the present results, it is concluded that both hKCNE4 and mKCNE4 have a drastic inhibitory impact on both hKCNQ1 and mKCNQ1 currents. PMID: 15707997
    11. The non-synonymous single nucleotide polymorphism E145D may be associated with the atrial fibrillation phenotype. PMID: 17016049
    12. KCNE4 directly associates with KCNQ1, and can co-associate together with KCNE1 in the same KCNQ1 complex to form a 'triple subunit' complex (KCNE1-KCNQ1-KCNE4). PMID: 18279388
    13. MiRP3 (encoded by the KCNE4 gene) plays a role in modulation of BK-dependent urinary potassium excretion. PMID: 18463315
    14. Specific KCNE4 domains responsible for the inhibitory effects on heterologously expressed KCNQ1 were identified. The KCNE4 C-terminus is critical for KCNQ1 modulation and physically interacts with KCNQ1. PMID: 19029186
