  • 共軛：
    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.

  • 蛋白標簽：
    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.
  • 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.
  • Datasheet ：

靶點詳情

  • 功能：
    Component of the cleavage and polyadenylation specificity factor (CPSF) complex that play a key role in pre-mRNA 3'-end formation, recognizing the AAUAAA signal sequence and interacting with poly(A) polymerase and other factors to bring about cleavage and poly(A) addition. CPSF4 binds RNA polymers with a preference for poly(U).
  • 基因功能參考文獻：
    1. The authors define the molecular architecture of the core human CPSF complex comprising CPSF160, WDR33, CPSF30 and Fip1 and identify specific domains involved in inter-subunit interactions. Together, these results shed light on the function of CPSF in mediating polyA signal-dependent RNA cleavage and polyadenylation. PMID: 29274231
    2. Residues F103 and M106 within the NS1-CPSF4 binding region are important for viral replication. PMID: 28554059
    3. Cleavage and polyadenylation specific factor 4 targets NF-kappaB/cyclooxygenase-2 signaling to promote the growth and survival of non-small cell lung carcinoma cells. PMID: 27450326
    4. These findings support a role for iron in some zinc-finger proteins. Using electrophoretic mobility shift assays and fluorescence anisotropy, we report that CPSF30 selectively recognizes the AU-rich hexamer (AAUAAA) sequence present in pre-mRNA, providing the first molecular-based evidence to our knowledge for CPSF30/RNA binding. PMID: 27071088
    5. unexpectedly found that CPSF subunits CPSF30 and Wdr33 directly contact AAUAAA PMID: 25301780
    6. CPSF4 upregulates human TERT promoter activity, human TERT expression and telomerase activity. PMID: 24618080
    7. Data show that 4 drug-like compounds from traditional Chinese Medicine (TCM) database were selected as potential inhibitors for the cleavage and polyadenylation specific factor CPSF30-binding site of influenza A virus of non-structural protein 1 (NS1A). PMID: 24562912
    8. CPSF4 plays a critical role in regulating lung cancer cell proliferation and survival and may be a potential prognostic biomarker and therapeutic target for lung adenocarcinoma. PMID: 24358221
    9. Data show that the NS1A protein of the pathogenic H5N1 influenza A/Hong Kong/483/97 (HK97) virus isolated from humans has an intrinsic defect in CPSF30 binding. PMID: 17522219
