Conjugate 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 Info The following tags are available.
N-terminal His-tagged
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.
Form 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.
Buffer before Lyophilization Tris/PBS-based buffer, 6% Trehalose, pH 8.0
Reconstitution 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.

Storage Condition Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw cycles.
Shelf Life 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.
Lead Time 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.
Notes Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

Target Background

Catalyzes the first step in ubiquitin conjugation to mark cellular proteins for degradation through the ubiquitin-proteasome system. Activates ubiquitin by first adenylating its C-terminal glycine residue with ATP, and thereafter linking this residue to the side chain of a cysteine residue in E1, yielding a ubiquitin-E1 thioester and free AMP. Essential for the formation of radiation-induced foci, timely DNA repair and for response to replication stress. Promotes the recruitment of TP53BP1 and BRCA1 at DNA damage sites.
Gene References into Functions
  1. Polyubiquitination and proteasomal degradation of ezrin and CUGBP1 require Uba6, but not Uba1, and that Uba6 is involved in the control of ezrin localization and epithelial morphogenesis. These data suggest that distinctive substrate pools exist for Uba1 and Uba6 that reflect non-redundant biological roles for Uba6. PMID: 28134249
  2. Results from a study on gene expression variability markers in early-stage human embryos shows that UBA1 is a putative expression variability marker for the 3-day, 8-cell embryo stage. PMID: 26288249
  3. recent findings put UBA1 at the center of cellular homeostasis and neurodegeneration [review] PMID: 26432019
  4. A ubiquitin shuttle DC-UbP reconciles protein ubiquitination and deubiquitination via linking UbE1 and USP5 enzymes. PMID: 25207809
  5. Conjugation of the ubiquitin activating enzyme UBE1 with the ubiquitin-like modifier FAT10 targets it for proteasomal degradation PMID: 25768649
  6. Ubiquitin-activating enzyme is necessary for 17beta-estradiol-induced breast cancer cell proliferation and migration. PMID: 25138535
  7. We expressed and purified the N-terminal domains of human E1 and determined their crystal structures, which contain inactive adenylation domain (IAD) and the first catalytic cysteine half-domain (FCCH) PMID: 25209502
  8. Diminished ubiquitylation phenotype observed in enteropathogenic Escherichia coli infected cells corresponds to a strong reduction in the abundance of both Ube1 and Uba6. PMID: 22999844
  9. Decrease in free ubiquitin levels under stress allows NEDD8 to be conjugated through Ube1. PMID: 22370482
  10. UBA1 knockdown impairs formation of ubiquitin conjugates at DNA double-strand breaks. PMID: 22456334
  11. Data show that largazole and ester/keto analogs inhibit ubiquitin E1 activation. PMID: 22279528
  12. In conclusion, nUBE1L is a novel human E1 like gene highly expressed in adult testis, which plays key role in ubiquitin system, and accordingly influences spermatogenesis and male fertility. PMID: 15202508
  13. analysis of ATP.Mg2+ binding in the catalytic cycle of ubiquitin-activating enzyme PMID: 16595681
  14. unusual type of regulation at the level of the E1 enzyme is likely to affect numerous cellular processes and may represent a strategy to coordinate multiple phenotypic changes upon differentiation by using E1 as a "master switch." PMID: 17060614
  15. Human Uba6 and Ube1 have distinct preferences for E2 charging in vitro, and their specificity depends in part on their C-terminal ubiquitin-fold domains, which recruit E2s PMID: 17597759
  16. Large-scale mutation analysis in genes resulted in detection of 3 rare novel variants in exon 15 of UBE1 that segregate with X-linked infantile spinal muscular atrophy. PMID: 18179898
  17. high-level expression of UBE1 was seen inextranodal NK/T cell lymphoma, nasal type; there was no significant difference between UBE1 expression and patients' outcome PMID: 18661401
