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
Strongly activates transcription when bound to HCFC1. Suppresses the expression of HSV proteins in cells infected with the virus in a HCFC1-dependent manner. Also suppresses the HCFC1-dependent transcriptional activation by CREB3 and reduces the amount of CREB3 in the cell. Able to down-regulate expression of some cellular genes in CREBZF-expressing cells.
Gene References into Functions
  1. Zhangfei/CREBZF stabilizes p53 and co-localizes with it in cellular nuclei; the bLZip domain of Zhangfei is required for its profound effects on cell growth and interaction with p53. PMID: 24200963
  2. Zhangfei had a suppressive effect on most unfolded protein response genes. PMID: 24155933
  3. Results indicate that Ursodeoxycholic acid (UDCA) activates SMILE gene expression, which leads to repression of liver X receptor alpha (LXRalpha)-mediated hepatic lipogenic enzyme gene expression. PMID: 24265317
  4. Our objective was to determine the molecular mechanisms by which Zhangfei influences medulloblastoma cell lines PMID: 22798206
  5. The transcription factor CREBZF is a novel positive regulator of p53. PMID: 22983008
  6. CREBZF, a novel Smad8-binding protein. PMID: 22707059
  7. a microarray study of SMILE knock-down and PMA activation in HeLa cells was compared to earlier analysis based on microarray data of kidney allograft tolerance and rejection to determine possible new genes and gene networks involved in kidney transplantation PMID: 22134986
  8. the curcumin/LKB1/AMPK/SMILE/PGC1alpha pathway differentially regulates ER stress-mediated gene transcription PMID: 21994947
  9. SMILE is involved in the endoplasmic reticulum stress response, by modulating proteasome activity and XBP-1 transcript expression. This function of SMILE may influence immune cell behavior in the context of transplantation. PMID: 21603654
  10. These results indicate that SMILE isoforms regulate the inhibition of estrogen receptor transactivation by SHP in a cell-type-specific manner and act as a novel transcriptional co-regulator in ER signalling. PMID: 18657049
  11. findings showed Zhangfei activated the expression of trkA and Egr1 in medulloblastoma cells and caused these cells to display markers of apoptosis PMID: 18719857
  12. SMILE is a novel corepressor of ERRgamma, and SIRT1 has a role as a novel repressive mechanism for SMILE and ERRgamma inverse agonist PMID: 19690166
  13. ZF suppresses the ability of Luman/CREB3 to activate gene expression PMID: 15705566
  14. ZF suppresses the ability of VP16 to activate herpes simplex virus IE gene expression PMID: 16282471
  15. ZF binds ATF4/CREB2 and enhances its response to MEK1 activation. PMID: 16343488
  16. Zhangfei causes medulloblastoma cells to undergo apoptosis PMID: 18719857
  17. In differentiated PC12 cells, Zhangfei activated the trkA promoter and induced the expression of endogenous trkA. PMID: 19016376
