    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.

    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.

靶点详情

  • 功能：
    Plays a key role in the activation of the host resting B-cell and stimulation of B-cell proliferation. Acts by up-regulating the expression of viral EBNA1-6, LMP1, LMP2A and LMP2B genes, as well as several host genes including CD21, CD23 and MYC. Activates transcription by acting as an adapter molecule that binds to cellular sequence-specific DNA-binding proteins such as host CBF1, SMARCB1 and SPI1. Once EBNA2 is near promoter sites, its acidic activating domain recruits basal and activation-associated transcription factors TFIIB, TAF40, TFIIH components ERCC2 and ERCC3, and CBP in order to promote transcription. Alternatively, EBNA2 can affect activities of cell cycle regulators and retard cell cycle progression at G2/M phase. It also induces chromosomal instability, by disrupting mitotic checkpoints, multi-nucleation and formation of micronuclei in infected cells.

    1. Identified three independent domains within EBNA2 that act through species-specific mechanisms. Importantly, the EBNA2 orthologues and species-specific EBNA2 domains separate unique roles for EBNA2 in the initiation of B cell immortalization from those responsible for maintaining the immortalized state. PMID: 29261800
    2. This study identifies the BS69 C-terminal domains as an inhibitor of EBNA2. PMID: 26845565
    3. s show that human herpesvirus 4 EBNA2 represses BIK in B-cell lymphoma-derived cell lines and that this host-virus interaction can inhibit the proapoptotic effect of transforming growth factor beta1. PMID: 24554662
    4. PRMT5 triggers the symmetric dimethylation of EBNA2 RG domain to coordinate with EBNA2-mediated transcription. PMID: 23261437
    5. present data suggest that EBNA2 might contribute to EBV-induced B-cell transformation by increasing oncomiR-like miR-21 and by affecting the antiviral responses of the innate immune system through downregulation of its key regulator miR-146a PMID: 22614176
    6. The subtypes E2-A and E2-C were the dominant genotypes of the EBNA-2 gene in nasopharyngeal and gastric carcinomas. PMID: 22348267
    7. mechanism by which the PhiW PhiP motif of RAM and EBNA2 compete with one another for binding at the hydrophobic pocket of the beta-trefoil domain (BTD) of CSL using overlapping but specific interactions that are unique to each BTD ligand. PMID: 20028974
    8. Inhibition of methylation in EBV-infected cells results in reduced expression of the EBNA2-regulated viral gene LMP1, evidencing that methylation is a prerequisite for DNA-binding by EBNA2 via association with the transcription factor RBPJkappa. PMID: 19969318
    9. data implicate EBNA2 Ser243 as a cdc2/cyclin B1 site of phosphorylation important for EBNA2's cotranscriptional function in mitosis PMID: 16439560
    10. results identify FcRH5 as a novel, direct target of EBNA2 that may contribute to the development of Epstein-Barr virus-associated tumors (Epstein-Barr virus nuclear antigen 2) PMID: 16439682
    11. EBNA2 trans-activates bfl-1, which requires CBF1 (or RBP-J kappa). PMID: 16873269
    12. p55alpha is thus a functional target of EBNA2 in EREB2.5 cells PMID: 16963743

    15. results indicate that differential gene regulation by Epstein-Barr virus type 1 and type 2 EBNA2 may be the basis for the much weaker B-cell transformation activity of type 2 Epstein-Barr virus strains compared to type 1 strains. PMID: 18480445
    16. EBNA2 is a transcriptional coactivator of STAT3 by influencing its DNA-binding activity. PMID: 19032945
    17. EBNA2 was shown to be able to downregulate mitotic arrest deficient 2 (MAD2) approximately 2- to 3-fold and upregulate polo-like kinase 1 (PLK1) approximately 2-fold. PMID: 19126642
    18. Both EBNA2 and Notch-IC induced the expression of proapoptotic genes, but only in EBNA2-expressing cells were antiapoptotic genes strongly up-regulated. PMID: 19339697
