    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.

  • 產品提供形式：
    Lyophilized powder Warning: in_array() expects parameter 2 to be array, null given in /www/web/cusabio_cn/public_html/caches/caches_template/default/content/show_product_protein.php on line 662
    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：
    Histone methyltransferase that catalyzes methyl group transfer from S-adenosyl-L-methionine to the epsilon-amino group of 'Lys-4' of histone H3 (H3K4) via a non-processive mechanism. Part of chromatin remodeling machinery predominantly forms H3K4me1 and H3K4me2 methylation marks at active chromatin sites where transcription and DNA repair take place. Likely plays a redundant role with KMT2C in enriching H3K4me1 marks on primed and active enhancer elements. Plays a central role in beta-globin locus transcription regulation by being recruited by NFE2. Plays an important role in controlling bulk H3K4me during oocyte growth and preimplantation development. Required during the transcriptionally active period of oocyte growth for the establishment and/or maintenance of bulk H3K4 trimethylation (H3K4me3), global transcriptional silencing that preceeds resumption of meiosis, oocyte survival and normal zygotic genome activation.

    1. Gene silencing experiments of MLL4 and the subunits PA1 and PTIP confirm TGF-beta-specific genes to be regulated by the MLL4 complex, which links TGF-beta signaling to transcription regulation by the MLL4 methyltransferase complex. PMID: 28976802

    4. In the univariate analyses, TP53, PPP1R3A, and KMT2B were significantly more frequently mutated in interval cancers than in screen-detected cancers. PMID: 27587435
    5. we describe a method to seamlessly modify a putative CDK2 phosphorylation site on MLL2 to restrict its phosphorylation and activation. Specifically, by utilizing dimeric CRISPR RNA-guided nucleases, RFNs (commercially known as the NextGENtrade mark CRISPR), in combination with an excision-only piggyBactrade mark transposase, we demonstrate how to generate a point mutation of threonine-542, a predicted site to prevent M...

    8. Results show that KMT2B interacts with ERalpha to bind the ERalpha-binding sites of IL-20 and other ERalpha target genes with H3K4 modifications suggesting an important role for KMT2B in the epigenetic transcriptional regulation of cytokine IL-20, and other ERalpha-responsive genes, in breast cancer cells. PMID: 27806114
    9. findings thus establish generalized dystonia as the human phenotype associated with haploinsufficiency of KMT2B; moreover, we provide evidence for a causative role of disordered histone modification, chromatin states, and transcriptional deregulation in dystonia pathogenesis PMID: 27839873
    10. The results explain how the MLL SET domains of MLL1 and MLL4 are able to add multiple methyl groups to the target histone H3 lysine. PMID: 26320581
    11. The Aven RGG/RG motif bound G4 structures within the coding regions of the MLL1 and MLL4 mRNAs increasing their polysomal association and translation, resulting in the induction of transcription of leukemic genes. PMID: 26267306
    12. We propose that MLL3 and MLL4 are broadly required for controlling MAFA and MAFB transactivation during development and postnatally. PMID: 26180087
