    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.

  • 功能：
    Dual specificity kinase acting on both serine/threonine and tyrosine-containing substrates. Phosphorylates serine- and arginine-rich (SR) proteins of the spliceosomal complex and may be a constituent of a network of regulatory mechanisms that enable SR proteins to control RNA splicing. Phosphorylates: SRSF1, SRSF3 and PTPN1. Regulates the alternative splicing of tissue factor (F3) pre-mRNA in endothelial cells and adenovirus E1A pre-mRNA.
  • 基因功能参考文献：
    1. We now show that the ability of SRPK1 to mobilize SRSF1 from speckles to the nucleoplasm is dependent on active CLK1. Diffusion from speckles is promoted by the formation of an SRPK1-CLK1 complex that facilitates dissociation of SRSF1 from CLK1 and enhances the phosphorylation of several serine-proline dipeptides in this SR protein PMID: 29335301
    2. Data suggest that CLK1 activity in both transformed and normal cells is carefully regulated via CLK1 alternative splicing through both exon 4 skipping and intron 4 retention. CLK1 autoregulates by favoring the expression of truncated isoforms, CLK1T1 and CLKT2 in environmental stress. PMID: 29802995
    3. These results thus reveal a large program of CLK1-regulated periodic alternative splicing intimately associated with cell cycle control. PMID: 27015110
    4. Global CLK-dependent exon recognition and conjoined gene formation revealed with a novel small molecule inhibitor has been described. PMID: 28232751
    5. that mitochondrial Clk1 regulated chemoresistance in glioma cells through AMPK/mTOR/HIF-1alpha mediated glycolysis pathway PMID: 28581641
    6. SRPK1 interacts with an RS-like domain in the N terminus of CLK1 to facilitate the release of phosphorylated SR proteins, which then promotes efficient splice-site recognition and subsequent spliceosome assembly. PMID: 27397683
    7. Clk1, Clk2 and Clk4 prevent chromatin breakage by regulating the Aurora B-dependent abscission checkpoint. PMID: 27126587
    8. removal of the N-terminus or dilution of CLK1 induces monomer formation and reverses this specificity. CLK1 self-association also occurs in the nucleus PMID: 26443864
    9. Nuclear CLK-1 mediates a retrograde signalling pathway that is conserved from Caenorhabditis elegans to humans and is responsive to mitochondrial reactive oxygen species, thus acting as a barometer of oxidative metabolism. PMID: 25961505
    10. Data suggest that proline phosphorylation by CLK1/CDC-like kinase 1 (but not by SRPK1/serine/arginine-rich splicing factor kinase 1) regulates conformation and alternative splicing function of SFRS1 (serine/arginine-rich splicing factor 1). PMID: 25529026
    11. findings suggest that CLK1-dependent hyperphosphorylation is the result of a general mechanism in which the N-terminus acts as a bridge connecting the kinase domain and the RS domain of the SR protein. PMID: 24869919
    12. The data establish a new view of SRSF1 protein regulation in which SRPK1 and CLK1 partition activities based on Ser-Pro versus Arg-Ser placement rather than on N- and C-terminal preferences along the RS domain. PMID: 23707382
    13. CLK1 Increases While CLK2 Decreases HIV-1 Gene Expression. PMID: 21682887
    14. Clk/Sty is found in the nucleus of several different cell types and is a factor directly involved in splicing control PMID: 12773558
    15. ASF/SF2 is phosphorylated by SRPK1 and Clk/Sty PMID: 16223727
    16. Cdc2-like kinases and DNA topoisomerase I regulate alternative splicing of tissue factor in human endothelial cells. PMID: 19168442
