    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.

  • 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.

  • 功能：
    Component of the RNF20/40 E3 ubiquitin-protein ligase complex that mediates monoubiquitination of 'Lys-120' of histone H2B (H2BK120ub1). H2BK120ub1 gives a specific tag for epigenetic transcriptional activation and is also prerequisite for histone H3 'Lys-4' and 'Lys-79' methylation (H3K4me and H3K79me, respectively). It thereby plays a central role inb histone code and gene regulation. The RNF20/40 complex forms a H2B ubiquitin ligase complex in cooperation with the E2 enzyme UBE2A or UBE2B; reports about the cooperation with UBE2E1/UBCH are contradictory. Required for transcriptional activation of Hox genes. Recruited to the MDM2 promoter, probably by being recruited by p53/TP53, and thereby acts as a transcriptional coactivator. Mediates the polyubiquitination of isoform 2 of PA2G4 in cancer cells leading to its proteasome-mediated degradation.

    1. the RNF20/40 complex, a major ubiquitin ligase catalysing histone H2B monoubiquitination, interacts with the motor protein Eg5 during mitosis and participates in spindle assembly. PMID: 27557628
    2. data indicate that RNF20 and PARP1 are synthetic lethal interactors PMID: 28462496
    3. RNF20 depletion stabilizes the ZSCAN4 protein half-life, suggesting that RNF20 negatively regulates ZSCAN4 stability. PMID: 29477841
    4. The effects of RNF20 on mammary tumorigenesis are subtype dependent: In basal-like cancers cells, RNF20 suppresses the NF-kappaB-dependent expression of cytokines, known to contribute to the growth of this tumor subtype. PMID: 28157208
    5. The authors also show that the RING domains of RNF20 and RNF40 can form a stable heterodimer that is active. PMID: 27569044
    6. Manipulation of key H2Bub1 E3 ubiquitin ligases, RNF20, RNF40 and BRCA1, in ovarian cancer cell line models modulated H2Bub1 levels, indicative of the role of these RING finger ligases in monoubiquitination of H2Bub1 in vitro PMID: 27798111
    7. RNF20 and H2Bub1 promotes chronic colonic inflammation and inflammation-associated colorectal cancer in mice and humans, partly by augmenting NF-kappaB activity and attenuating the antitumoral T cell response. PMID: 26854224
    8. It was observed that RE-IIBP induces MEIS1-mediated apoptosis, which was dependent on H2BK120 ubiquitination by RNF20. PMID: 26206755

    11. model whereby cotranscriptional recruitment of Rnf20 at MLL-fusion target genes leads to amplification of Dot1l-mediated H3K79 methylation, thereby rendering leukemia cells dependent on Rnf20 to maintain their oncogenic transcriptional program PMID: 23412334
    12. We show that Bre1 (human BRE1A/B (RNF20/40) and mouse Bre1a/b (Rnf20/40)) acts as an important suppressor of chromosomal instability PMID: 22354749
    13. our results suggest that RNF20 and RNF40, either via ubiquitylation of H2B or other targets, are coupled to the proliferation of prostate cancer cells. PMID: 22155569
    14. Studies indicate that H2B monoubiquitylation is driven primarily by an E3 ubiquitin ligase composed of the two RING finger proteins RNF20 and RNF40. PMID: 21827756
    15. RNF20, presumably via H2Bub, selectively represses oncogenic genes by interfering with chromatin recruitment of TFIIS, a factor capable of relieving stalled RNA polymerase II. RNF20 inhibits the interaction between TFIIS and the PAF1 complex. PMID: 21596312
    16. RNF20-mediated H2B ubiquitination at DSBs plays a critical role in HRR through chromatin remodeling PMID: 21362548
    17. the observed defects in the radiation response of Bre1a/b-deficient cells PMID: 20738173
    18. RNF20 overexpression leads to elevated histone 2B monoubiquitination, subsequently higher levels of methylation at H3 lysines 4 and 79, and stimulation of homeobox gene expression. PMID: 16307923
    19. The Bre1 protein specifically increases the global level of H2B ubiquitylation at lysine 120 and enhances activator-dependent transcription. PMID: 16337599
    20. identified as one of five genes containing 11 somatic mutations in a panel that included 132 colorectal cancers, then demonstrated that down-regulation of such homologs resulted in chromosomal instability and chromatid cohesion defects in human cells PMID: 18299561
    21. RNF20 suppresses the expression of several proto-oncogenes, which reside preferentially in closed chromatin and are modestly transcribed despite bearing marks usually associated with high transcription rates. PMID: 18832071
