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.
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
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.
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.
Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

Target Background

Key regulator of inflammation, lipid metabolism and mitochondrion homeostasis that acts by inhibiting the activity of the ubiquitin-conjugating enzyme UBE2N/Ubc13, thereby inhibiting 'Lys-63'-linked ubiquitination. In the nucleus, can both acts as a corepressor and coactivator of transcription, depending on the context. Acts as a transcription coactivator in adipocytes by promoting the recruitment of PPARG to promoters: acts by inhibiting the activity of the ubiquitin-conjugating enzyme UBE2N/Ubc13, leading to stabilization of KDM4A and subsequent histone H3 'Lys-9' (H3K9) demethylation. Promotes cholesterol efflux by acting as a transcription coactivator. Acts as a regulator of B-cell development by inhibiting UBE2N/Ubc13, thereby restricting the activation of Toll-like receptors (TLRs) and B-cell antigen receptors (BCRs) signaling pathways. Acts as a key mediator of mitochondrial stress response: in response to mitochondrial depolarization, relocates from the mitochondria to the nucleus following desumoylation and specifically promotes expression of nuclear-encoded mitochondrial genes. Promotes transcription of nuclear-encoded mitochondrial genes by inhibiting UBE2N/Ubc13. Can also act as a corepressor as part of the N-Cor repressor complex by repressing active PPARG. Plays an anti-inflammatory role in macrophages and is required for insulin sensitivity by acting as a corepressor. Plays an anti-inflammatory role during the hepatic acute phase response by interacting with sumoylated NR1H2 and NR5A2 proteins, thereby preventing N-Cor corepressor complex dissociation. In the cytosol, also plays a non-transcriptional role by regulating insulin signaling and pro-inflammatory pathways. In the cytoplasm, acts as a negative regulator of inflammation by inhibiting the proinflammatory TNF-alpha pathway; acts by repressing UBE2N/Ubc13 activity. In the cytoplasm of adipocytes, restricts the activation of insulin signaling via inhibition of UBE2N/Ubc13-mediated ubiquitination of AKT. Able to suppress G-protein- and mitogen-activated protein kinase-mediated signal transduction. Acts as a tumor-suppressor in liposarcoma.; (Microbial infection) Required for efficient replication of hepatitis C virus (HCV) by promoting the interaction between VAPA and HCV virus protein NS5A.

  1. The study of adipose tissue from humans with and without obesity revealed correlations between reduced GPS2 expression in macrophages, elevated systemic and adipose tissue inflammation, and diabetic status. PMID: 27270589
  2. our studies identify GPS2 functions as a tumor suppressor in LPS and its downregulation is correlated to prognosis of LPS. PMID: 27460081
  3. Posttranslational modification of GPS2 by SUMOylation may serve as a key factor that regulates the function of GPS2 in vivo. PMID: 24943844
  4. regulation of GPS2 by posttranslational modifications provides an effective strategy for modulating its molecular function within the nuclear compartment. PMID: 26070566
  5. Chromosomal translocation in a pediatric undifferentiated spindle cell sarcoma have characterized this alteration to show rearrangement of the MLL4 and GPS2 genes, resulting in fusion gene MLL4-GPS2, the expression of which promotes independent growth. PMID: 25139254
  6. GPS2 is required for the association of viral NS5A with VAP-A and hepatitis C virus replication. PMID: 24223774
  7. expression of the transcriptional corepressor complex subunits GPS2 and SMRT was significantly reduced in obese adipose tissue, inversely correlated to inflammatory status PMID: 23221346
  8. Results show for the first time that GPS-2 is differentially methylated at a site that lacks known methylation motifs and that the methylation state is detected by the immune system PMID: 19917673
  9. metabolically important coregulator GPS2 functions as a hitherto unrecognized transrepression mediator of interactions between SUMOylated nuclear receptors and the N-CoR corepressor complex PMID: 20159957
