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
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.
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.
Troubleshooting and FAQs
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

Function
Binds to the X-box motif of MHC class II genes and represses their expression. May play an important role in regulating the duration of an inflammatory response by limiting the period in which MHC class II molecules are induced by interferon-gamma. Isoform 3 binds to the X-box motif of TERT promoter and represses its expression. Together with PABPC1 or PABPC4, isoform 1 acts as a coactivator for TERT expression. Mediates E2-dependent ubiquitination.
Gene References into Functions
  1. This study identifies NFX1-123 as a critical host protein partner through which 16E6 is able to subvert the immune response and in turn permit a long-lived high-risk Human papillomavirus infection. PMID: 29117186
  2. The results showed that a repressor complex composed of NFX1-91, mSin3A and histone deacetylase 1 was involved in the PKC-delta-induced repression of the hTERT promoter, which resulted in the repression of hTERT transcription. PMID: 27311997
  3. Human papillomavirus 16 E6 (16E6) interacts with the cellular protein NFX1-123, and they collaboratively increase the growth and differentiation master regulator, Notch1. PMID: 25723053
  4. NFX1-123 and human papillomavirus 16E6 upregulated Notch 1 expression in keratinocytes. PMID: 24109236
  5. HuD acts as a novel adaptor protein to recruit TAP for efficient export of ARE-containing mRNAs in neuronal cells PMID: 15358174
  6. the induction of hTERT telomerase by the HPV-16 E6/E6-AP complex involves targeting of NFX1-91, a newly identified repressor of telomerase, for ubiquitination and degradation. PMID: 15371341
  7. Nrf1 is normally targeted to the endoplasmic reticulum membrane and endoplasmic reticulum stress may play a role in modulating Nrf1 function as a transcriptional activator PMID: 16687406
  8. data suggest that NFX1-123 is integral to hTERT regulation in HPV16 E6-expressing epithelial cells and that the interaction between NFX1-123 and poly(A) binding proteins is critical to hTERT activity PMID: 17267499
  9. These data demonstrate that targeted degradation of NFX1-91 by E6/E6AP dissociates the mSin3A/HDAC complex from the hTERT promoter and induces hTERT transcription. PMID: 18505829
  10. NFX1-123 is a cytoplasmic protein that colocalizes with poly(A) binding proteins, and binds hTERT mRNA in HPV16 E6-expressing keratinocytes. PMID: 19369336
