    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.

    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：
    Associates with KCNQ2 or KCNQ5 to form a potassium channel with essentially identical properties to the channel underlying the native M-current, a slowly activating and deactivating potassium conductance which plays a critical role in determining the subthreshold electrical excitability of neurons as well as the responsiveness to synaptic inputs. Therefore, it is important in the regulation of neuronal excitability.
  • 基因功能參考文獻(xiàn)：
    1. Phylogenetic analysis, electrostatic potential mapping, in silico docking, electrophysiology, and radioligand binding assays reveal that the anticonvulsant binding pocket evolved to accommodate endogenous neurotransmitters including gamma-aminobutyric acid, which directly activates KCNQ5 and KCNQ3 via W265. PMID: 29748663
    2. Tannic acid activates Kv7.4 and Kv7.3/7.5 K(+) channels resulting in vasodilation. PMID: 26969140
    3. Carboxyl terminus helix C-D linker residues play a role in KCNQ3 current amplitudes by controlling the exit of the KCNQ3 channel from the endoplasmic reticulum. PMID: 26692086
    4. In bipolar disorder patients' prefrontal cortex, Kcnq3 expression was decreased, DNA methylation was decreased, and Kcnq3 mRNA was decreased compared to controls. PMID: 25041603
    5. the clinical and EEG features of this patient further on expand the phenotypic variability of KCNQ3 gene mutations PMID: 25278462
    6. mutations in KCNQ3, similarly to KCNQ2, can be found in patients with more severe phenotypes including intellectual disability PMID: 25524373
    7. We monitored KCNQ2/3 channel currents and translocation of PHPLCdelta1 domains as real-time indicators of PM PI(4,5)P2, and translocation of PHOSH2x2, and PHOSH1 domains as indicators of plasma membrane and Golgi PI(4)P, respectively. PMID: 24843134
    8. This study demonistrated that benign neonatal sleep myoclonus can show autosomal dominant inheritance but not allelic to KCNQ3. PMID: 22447848
    9. KCNQ3 mutations might be involved in families with infantile seizures. PMID: 23360469
    10. Data show that KCNQ3 and KCNE5 mRNA expressions were significantly upregulated in preeclampsia. PMID: 21730298
    11. Different structural determinants, identified at the N and C termini of KCNQ3, prevent the effects of syntaxin 1A and calmodulin, respectively. PMID: 21976501
    12. This study reported that the presence of this uncommon residue at position 315 has a strong impact on the stability of the homotetramers and on channel trafficking. PMID: 20610766
    13. There may be a genetic contribution of this gene in juvenile myoclonic epilepsy in a South Indian population. PMID: 12928862
    14. Several BFNC mutations of KCNQ2 and KCNQ3 disrupt surface expression or polarized surface distribution of KCNQ channels, thereby revealing impaired targeting of KCNQ channels to axonal surfaces as a benign familial neonatal convulsions (BFNC) etiology. PMID: 16735477
    15. ICA-27243 is a novel and selective KCNQ3 potassium channel activator. PMID: 18089837
    16. The expression of KCNQ3 increased in late fetal life to infancy in brain. PMID: 18166285
    17. This study identified a novel missense mutation of KCNQ3, c.988C>T located within exon 6. c.988C>T led to the substitution Cys for Arg in amino acid position 330 (p.R330C) in KCNQ3 potassium channel. PMID: 18249525
    18. A three-dimensional homology model in the W309R mutant indicated that the R side chain of pore helices is too far from the Y side chain of the selectivity filter to interact via hydrogen bonds with each other and stabilize the pore structure. PMID: 18425618
    19. Sequence variations of the KCNQ2 (and KCNQ3)genes may contribute to the etiology of common idiopathic epilepsy syndromes. PMID: 18625963
    20. among the allowed assembly conformations are KCNQ3/4 and KCNQ4/5 heteromers. PMID: 18786918
    21. most wild-type channels are functionally silent, with rearrangements of the pore-loop architecture induced by the presence of a hydroxyl-containing residue at the 315 position "unlocking" the channels into a conductive conformation PMID: 18790849
