    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.
  • 儲存條件：
    Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw cycles.
  • 保質期：
    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：
    Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

靶點詳情

  • 功能：
    Functions as an E3 ubiquitin-protein ligase and as an E3 SUMO1-protein ligase. Probable tumor suppressor involved in cell growth, cell proliferation and apoptosis that regulates p53/TP53 stability through ubiquitin-dependent degradation. May regulate chromatin modification through sumoylation of several chromatin modification-associated proteins. May be involved in DNA damage-induced cell death through IKBKE sumoylation.
  • 基因功能參考文獻：
    1. A novel mutation of the TOPORS gene was identified, c.2539C>T p.(Arg847Ter), resulting in a premature termination codon and suggesting haploinsufficiency as the pathological mechanism. PMID: 28453362
    2. P26s4 Associates with the C-Terminal Region of TOPORS. PMID: 26872363
    3. Data suggest that TOPORS plays key role in turnover of H2AX (H2A histone family, member X protein) depending on the type of oxidative stress/DNA damage; TOPORS may act as an E3 ubiquitin ligase for histones. PMID: 22972498
    4. Disturbed flow induces peroxynitrite production and binding to the E3 SUMO (small ubiquitin-like modifier) ligase PIASy (protein inhibitor of activated STATy). PMID: 21624951
    5. In photoreceptors, TOPORS localizes primarily to the basal bodies of connecting cilium and in the centrosomes. PMID: 21159800
    6. Polo-like kinase 1 (Plk1)-associated phosphorylation of Topors at S718 is essential for nocodazole-induced degradation of Topors. PMID: 19821153
    7. We present a novel mutation in the TOPORS gene co-segregating with a distinct phenotype of adPRD in a large Norwegian family. PMID: 19183411
    8. Topors, a p53 and topoisomerase I binding protein, interacts with the adeno-associated virus (AAV-2) Rep78/68 proteins and enhances AAV-2 gene expression PMID: 11842245
    9. topors localizes in punctate nuclear regions associated with PML protein nuclear bodies. PMID: 12083797
    10. Multiple SUMO-1 modified forms of Topors could be detected after cotransfection of exogenous SUMO-1 and Topors induced the colocalization of a YFP tagged SUMO-1 protein in a speckled pattern in the nucleus. PMID: 14516784
    11. topors functions as a negative regulator of cell growth, and possibly as a tumor suppressor PMID: 15107820
    12. topors has a role as an E3 ubiquitin ligase with specific E2 enzymes and ubiquitinates p53 PMID: 15247280
    13. Results show that the ATR/checkpoint kinase 1 pathway plays a predominant role in the response to topoisomerase I inhibitors in carcinoma cells. PMID: 15699047
    14. topors mediates p53-dependent cellular responses induced by DNA damage, suggesting its physiological role as a tumor suppressor PMID: 15735665
    15. Data show that Topors enhances the conjugation of the small ubiquitin-like modifier 1 (SUMO-1) to p53 in vivo and in a reconstituted in vitro system. PMID: 16122737
    16. The findings suggest that TOPORS may function as a tumor suppressor by regulating mSin3A and other proteins involved in chromatin modification. PMID: 17803295
    17. Mutations in the gene for topoisomerase I-binding RS protein (TOPORS) in patients with autosomal dominant retinitis pigmentosa (adRP) linked to chromosome 9p21.1 (locus RP31), is reported. PMID: 17924349
    18. Topors enhances the formation of high-molecular weight SUMO-1 conjugates of TOP1 in a reconstituted in vitro system and also in human osteosarcoma cells PMID: 17976381
    19. NKX3.1 can be ubiquitinated by TOPORS in vitro and in vivo, and overexpression of TOPORS leads to NKX3.1 proteasomal degradation in prostate cancer cells PMID: 18077445
    20. Point mutations and small insertions or deletions in TOPORS cause approximately 1% of autosomal dominant retinitis pigmentosa. PMID: 18509552
    21. Mutations in TOPORS cause autosomal dominant retinitis pigmentosa (adRP). PMID: 19373681
