    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.
  • Datasheet ：

  • 功能：
    One of the multiple factors required for polyadenylation and 3'-end cleavage of mammalian pre-mRNAs. This subunit is directly involved in the binding to pre-mRNAs.
  • 基因功能参考文献：
    1. hnRNP H binds to two specific G-runs in exon 5a of ACHE and activates the distal alternative 3 splice site (ss) between exons 5a and 5b. Furthermore, hnRNP H competes for binding of CstF64 to the overlapping binding sites in exon 5a, and suppresses the selection of a cryptic polyadenylation site, which additionally ensures transcription of the distal 3 ss required for the generation of AChET isoform. PMID: 28180311
    2. CstF-64 is dispensable for the expression/3'-end processing of Star-PAP target mRNAs.CstF-64 and 3'-UTR cis-element determine Star-PAP specificity for target mRNA selection by excluding poly A polymerase. PMID: 26496945
    3. CstF64, an essential polyadenylation factor, is a master regulator of 3'-UTR shortening across multiple tumour types. PMID: 25409906
    4. CstF64 is central to the function of a heat-labile factor, composed of cleavage/polyadenylation specificity factor, symplekin, and cleavage stimulation factor 64 and appears to be at least partly responsible for its cell cycle regulation. PMID: 25266659
    5. CstF64 and CstF64tau modulate one another's expression and play overlapping as well as distinct roles in regulating global alternative polyadenylation profiles. PMID: 24149845
    6. CstF64 binds to thousands of dormant intronic PASs that are suppressed, at least in part, by U1 small nuclear ribonucleoproteins PMID: 23112178
    7. CSTF2 is likely to play an important role in lung carcinogenesis and be a prognostic biomarker in the clinic. PMID: 21813631
    8. nuclear accumulation of CstF-64 depends on binding to CstF-77 not symplekin; interaction between CstF-64/CstF-64Tau and CstF-77 are important for maintenance of nuclear levels of CstF complex components and intracellular localization, stability, function PMID: 21119002
    9. The Hinge domain is necessary for CstF-64 interaction with CstF-77 and consequent nuclear localization. PMID: 19887456
    10. dynamics of the CstF-64 RNA-binding domain, both free and bound to two GU-rich RNA sequences that represent polyadenylation regulatory elements, by NMR Spectroscopy PMID: 15769465
    11. The inactivity of the RSV poly(A) site was at least in part due to poor CstF binding since tethering CstF to the RSV substrate activated polyadenylation. PMID: 18272196
    12. CstF64 (cstf2) and not other CstF subunits induced by lipopolysaccharide (LPS) in murine macrophages and changes polyA site use PMID: 16207706
    13. Describes the induction of CSTF2 in the growth phase of cells. PMID: 9736695
