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

Target Background

Plays an essential role for the activation and immortalization of human B-cells. Represses transcription of viral promoters TP1 and Cp through interaction with host RBPJ, and inhibits EBNA2-mediated activation of these promoters. Since Cp is the promoter for all EBNA mRNAs, EBNA6 probably contributes to a negative autoregulatory control loop. Alternatively, EBNA6 also regulates the transcription of the EBV oncogene LMP1 in a cell cycle-dependent manner. Modulates the activity of several host proteins involved in cell cycle regulation including host cyclin A, MYC, RB, p21 and p27 mainly through binding to the host SCF(SKP2) complex. Inhibits the promoter of host H2AX and targets H2AX to proteasomal degradation in order to promote latency and cell proliferation.
Gene References into Functions
  1. Our results provide novel insights into the function of EBNA3C on cell progression by regulating the cyclin D2 protein and raise the possibility of the development of new anticancer therapies against EBV-associated cancers. PMID: 29997218
  2. EBNA3B restrains the oncogenic capacity of EBV, so it acts as a tumour suppressor.[review] PMID: 26428372
  3. EBNA3C is necessary to overcome an EBV-driven increase in p16(INK4a) expression and concomitant block to proliferation 2-4 weeks post-infection. PMID: 23436997
  4. The p73-mediated apoptotic pathway is inhibited in the presence of EBNA3C. PMID: 24314664
  5. During latency, out of a subset of viral genes expressed, EBNA-3C is one of the essential antigens required for in vitro primary B-cell transformation. PMID: 23464371
  6. This study provided formal proof that when EBV represses BIM transcription in B cells, expression of both EBNA3A and EBNA3C is necessary for the assembly of PRC2 on the BIM promoter and the deposition of the epigenetic repressive mark H3K27me3. PMID: 22584624
  7. EBNA3BKO virus caused highly proliferative, monomorphic B cell lymphomas in humanized mice. EBV+ human lymphoma samples had EBNA3B mutations. EBNA3B is a virus-encoded tumor suppressor. Loss promotes immune evasion & lymphomagenesis. PMID: 22406538
  8. we have unveiled key cellular pathways repressed by EBNA 3C that are likely to contribute to the ability of EBV-immortalized cells to modulate immune responses, adhesion, and B-lymphocyte migration to facilitate persistence in the host. PMID: 22357270
  9. EBNA3C gene variations are geographically restricted rather than tumor-specific polymorphisms. PMID: 22302288
  10. we report that EBNA3C directly interacts with Gemin3 through its C-terminal domains PMID: 22174681
  11. Epstein-Barr virus nuclear antigen 3C facilitates G1-S transition by stabilizing and enhancing the function of cyclin D1. PMID: 21347341
  12. EBNA3C negatively regulate p53-mediated functions by interacting with ING4 and ING5. PMID: 21177815
  13. EBV nuclear antigen 3C (EBNA3C) is an essential transcription factor for EBV transformed lymphoblast cell line growth, regulating 550 genes, 106 of which are recognized in protein networks. PMID: 21173222
  14. EBNA3C interacts with Gadd34, activating the upstream component of the unfolded protein response UPR (eIF2alpha phosphorylation) while preventing downstream UPR events (XBP1 activation and ATF6 cleavage). PMID: 20040105
  15. EBNA3C forms a stable complex with Rb in cells when the proteasome machinery is inhibited and interacts with Rb in vitro, mapping to a conserved domain at the terminus of EBNA3C PMID: 16352731
  16. findings show that both EBNA3C and Rhesus EBNA3C bind to a conserved region of mammalian cyclins, regulate pRb stability, and modulate SCF(Skp2)-dependent ubiquitination PMID: 16364389
  17. current knowledge of functions of EBNA 3C, the roles played by the different domains in these functions, and summary of recent work that provides the first structural and functional analysis of the putative bZIP domain of EBNA 3C [review] PMID: 16611138
  18. The effects of the EBV nuclear antigen 3C on the activities of Nm23-H1 via GATA-1 and Sp1 are reported. PMID: 16631833
