    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.

    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.

靶点详情

  • 功能：
    Ubiquitin-protein ligase that probably functions as an E3 ligase in conjunction with specific E1 and E2 ligases. May also function as an E4 ligase mediating the assembly of polyubiquitin chains on substrates ubiquitinated by another E3 ubiquitin ligase. May regulate myosin assembly in striated muscles together with STUB1 and VCP/p97 by targeting myosin chaperone UNC45B for proteasomal degradation.
  • 基因功能参考文献：
    1. miR-1301 functions as a tumor suppressor that inhibits tumor cell migration and invasion in multiple human cancer cells by regulating the UBE4B-p53 pathway. PMID: 28483517
    2. UBE4B promotes endogenous phospho-p53(S15) and phospho-p53(S392) degradation in response to gamma irradiation. UBE4B plays an important role in regulating phosphorylated p53 following DNA damage. PMID: 26673821
    3. UBE4B overexpression promotes the oncogenic properties of HCC and is correlated with an unfavorable prognosis in HCC patients. PMID: 25557723
    4. UBE4B regulates p53 in breast cancer PMID: 24587254
    5. We propose a model in which the coordinated action of UBE4B, ESCRT-0, and the deubiquitinating enzyme USP8 enable the endosomal sorting and lysosomal degradation of the EGFR. PMID: 24344129
    6. UBE4B-mediated growth factor receptor trafficking may contribute to the poor prognosis of patients who have neuroblastoma tumors with 1p36 deletions. PMID: 22990745
    7. The regulated expression of these UFD2a isoforms most likely imparts divergent functions that are important for myogenesis. PMID: 22174917
    8. we found somatic mutations of HERC2, HERC3, TRIP12, UBE2Q1 and UBE4B genes in gastric carcinoma and colorectal carcinomas with microsatellite instability PMID: 22124266
    9. data indicate that amplification and overexpression of UBE4B represent previously undescribed molecular mechanisms of inactivation of p53 in brain tumors PMID: 21317885
    10. determined structures of E4B U box free and bound to UbcH5c and Ubc4 E2s; findings show E4B U box is a monomer stabilized by a network of hydrogen bonds; findings suggest allosteric regulation of UbcH5c and Ubc4 by E4B U box PMID: 20696396
    11. A splice site mutation was found in UBE4b. UBE4B expression was diminished in the high-stage/poor-outcome tumors.UBE4B stands out as the strongest candidate NBL tumor suppressor gene in the region at this stage. PMID: 12700669
    12. E4B serves as a ubiquitin ligase for FEZ1 and thereby regulates its function but not its degradation PMID: 15466860
    13. we have identified a novel domain (the MPAC domain: Mitotically Phosphorylated, Apoptotically Cleaved) present at the N-terminus of Ufd2a, which is regulated both by cleavage during cell death, and by phosphorylation during mitosis. PMID: 16870146
    14. Our current study provides an insight onto the regulation of DeltaNp63alpha protein levels in response to cisplatin and also suggests that UFD2a might play an important role in the regulation of cisplatin mediated cell death mediated by p63. PMID: 18418053
