    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 ：

靶点详情

  • 功能：
    Histone chaperone that facilitates histone deposition and histone exchange and removal during nucleosome assembly and disassembly. Cooperates with chromatin assembly factor 1 (CAF-1) to promote replication-dependent chromatin assembly. Does not participate in replication-independent nucleosome deposition which is mediated by ASF1A and HIRA. Required for spermatogenesis.
  • 基因功能参考文献：
    1. histone binding to ASF1B is required for the induction of beta-cell proliferation. PMID: 27753532
    2. Data indicate Tousled-like kinases (TLK1) phosphorylation has an impact on cell cycle proteins Asf1a and Asf1b function. PMID: 24598821
    3. Co-depletion of the histone chaperones ASF1a and ASF1b in human cells induces all hallmarks of alternative lengthening of telomeres in both primary and cancer cells. PMID: 24413054
    4. Data indicate that miR-214 down-regulated the expression of PSMD10 (gankyrin) and ASF1B, and gankyrin inhibition induced an increase of P53 mRNA levels. PMID: 23100276
    5. study of the interaction of the histone H3-H4 complex with the RbAp48 and their exchange with a second histone chaperone, anti-silencing function protein 1 (ASF1); exchange of histones H3-H4 between these two histone chaperones has a central role in the assembly of new nucleosomes PMID: 23178455
    6. Asf1b, the necessary Asf1 isoform for proliferation, is predictive of outcome in breast cancer. PMID: 21179005
    7. Data show that Asf1b localizes with HCF-1 in viral replication foci and depletion of Asf1b results in significantly reduced viral DNA accumulation. PMID: 20133788
    8. Identify marks on histones H3-H4 bound to Asf1 and changes induced upon replication stress. PMID: 20227376
    9. ASF1 cellular levels are tightly controlled by distinct pathways and provide a molecular mechanism for post-translational regulation of dASF1 and hASF1a by TLK kinases. PMID: 20016786
    10. model is proposed in which the synergism between hAsf1 and CAF-1 for nucleosome formation during DNA repair is achieved through a transient physical interaction allowing histone delivery from Asf1 to CAF-1 [asf1(anti-silencing function 1)] PMID: 11897662
    11. data suggest that CIA-II is a histone chaperone and is implicated in the regulation of mammalian spermatogenesis PMID: 12842904
    12. Studies provide evidence for TLK1B-mediated phosphorylation of Asf1 triggering DNA repair. PMID: 17054786
    13. the expression of human ASF1A and ASF1B are upregulated followed by cell proliferation signal, but that of ASF1B is uniquely regulated by transcription factors E2F during cell cycle progression PMID: 17328667
    14. data link Asf1 chaperone function, histone supply, and replicative unwinding of DNA in chromatin; proposed that Asf1, as a histone acceptor and donor, handles parental and new histones at the replication fork via an Asf1-(H3-H4)-MCM2-7 intermediate PMID: 18096807
    15. ASF1A and ASF1B play a role in the efficiency of nucleosome assembly in vivo in human cells. PMID: 18378699
