    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.

  • 蛋白标签：
    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.
  • 货期：
    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.
  • 注意事项：
    Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.
  • Datasheet ：

  • 功能：
    Coup (chicken ovalbumin upstream promoter) transcription factor binds to the ovalbumin promoter and, in conjunction with another protein (S300-II) stimulates initiation of transcription. Binds to both direct repeats and palindromes of the 5'-AGGTCA-3' motif. Represses transcriptional activity of LHCG.
  • 基因功能参考文献：
    1. Whole-exome sequencing identified a novel missense NR2F1 variant in each case, Cys86Phe in the DNA-binding domain in Case 1, and a Leu372Pro in the ligand-binding domain in Case 2. Using molecular modeling we are also able to demonstrate the putative effect of the two missenses on protein function, generating a hitherto undescribed molecular model for the ligand-binding domain of NR2F1 in the process. PMID: 28963436
    2. fifth of COUP-TFI cells also co-expressed COUP-TFII, and cells expressing either transcription factor followed posterior or anterio-lateral pathways into the cortex PMID: 28922831
    3. Bosch-Boonstra-Schaaf optic atrophy syndrome (BBSOAS)encompasses a broad range of clinical phenotypes. Functional studies help determine the severity of novel NR2F1 variants. Some genotype-phenotype correlations seem to exist, with missense mutations in the DNA-binding domain causing the most severe phenotypes PMID: 26986877
    4. COUP-TFII is expressed in a diverse subset of GABAergic interneurons predominantly innervating small dendritic shafts originating from both interneurons and pyramidal cells. PMID: 25787832
    5. our mechanistic in vitro assays and in vivo results suggest that a reduction in chemokine CXCL12 expression, with an enhancement of CXCR4 expression, provoked by COUP-TFI, could be associated with an increase in the invasive potential of breast cancer PMID: 24906407
    6. NR2F1 has an important role in the development of the visual system and that haploinsuffiency can lead to optic atrophy with intellectual impairment. PMID: 24462372
    7. Interaction of NSD1 with the NR2E/F subfamily including COUP-TFI, COUP-TFII, EAR2 and TLX requires an F/YSXXLXXL/Y motif. Interactions of NSD1 with liganded NRs require an overlapping LXXLL motif. PMID: 23975195
    8. COUP-TFI and related NRs such as the COUPTFs and PNR can selectively associate with the developmental corepressor BCL11A via a conserved motif F/YSXXLXXL/Y within the RID1 and RID2 domains. The interaction with BCL11A facilitates COUP-TFII-mediated repression of the RARb2 gene. PMID: 23975195
    9. study identifies two unique corticotroph tumor populations which differ in their expression of COUP-TFI, the presence of which occurs more frequently in macroadenomas. PMID: 19526345
    10. provide detailed experimental validation of each step and, as a proof of principle, utilize the methodology to identify novel direct targets of the orphan nuclear receptor NR2F1 (COUP-TFI) PMID: 20111703
    11. Transcriptional and posttranscriptional mechanisms involving NR2F1 and IRE1beta ensure low microsomal triglyceride transfer protein expression in undifferentiated intestinal cells and avoid apolipoprotein B lipoprotein biosynthesis. PMID: 20007910
    12. Inhibit aldehyde dehydrogenase 2 gene expression PMID: 11811951
    13. Regulation of retinoic acid-induced inhibition of AP-1 activity by orphan receptor chicken ovalbumin upstream promoter-transcription factor. PMID: 11934895

    16. Transcription of the LHR gene is repressed by EAR3. PMID: 12972613
    17. COUP-TF may be involved in repression of the human MGP gene promoter at the myoblast stage PMID: 15157742
    18. findings show that enhancer II of HBV genotype A is also repressed by COUP-TF1; in contrast, two different enhancer II constructs of HBV genotype D were activated by COUP-TF1 PMID: 17009409
    19. COUP-TFI selectively regulates the expression of endogenous E2-target genes and consequently modifies ER alpha positive mammary cells response to E2. PMID: 17674191
