  • 蛋白標簽：
    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.
  • 產品提供形式：
    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.
  • 復溶：
    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.
  • 儲存條件：
    Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw cycles.
  • 保質期：
    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.
  • 貨期：
    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.
  • 注意事項：
    Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.
  • Datasheet ：

靶點詳情

  • 功能：
    Sequence-specific RNA-binding protein that binds to the cytoplasmic polyadenylation element (CPE), an uridine-rich sequence element (consensus sequence 5'-UUUUUAU-3') within the mRNA 3'-UTR. RNA binding results in a clear conformational change analogous to the Venus fly trap mechanism. Regulates activation of unfolded protein response (UPR) in the process of adaptation to ER stress in liver, by maintaining translation of CPE-regulated mRNAs in conditions in which global protein synthesis is inhibited. Required for cell cycle progression, specifically for cytokinesis and chromosomal segregation. Plays a role as an oncogene promoting tumor growth and progression by positively regulating translation of t-plasminogen activator/PLAT. Stimulates proliferation of melanocytes. In contrast to CPEB1 and CPEB3, does not play role in synaptic plasticity, learning and memory.
  • 基因功能參考文獻：
    1. Silencing of CPEB4 induces reactive oxygen species generation, thus suppressing the Akt expression, which finally prevents non-small cell lung cancer cells invasion and migration. PMID: 29286212
    2. This study identified a lineage-specific requirement of CPEB4 in malignant melanoma. PMID: 27857118
    3. Survival analysis revealed a significant association between progression free survival (PFS) and overall survival (OS) and CPEB4 immunohistochemical expression, which was independent in the multivariate analysis. CPEB4 behaves as a significant predictor of prognosis in stage IV colorectal carcinoma. PMID: 28551384
    4. The results implicate the potential role of CPEB4 and Vimentin in breast cancer metastasis, which is further confirmed by the finding that there is a physical interaction between the two proteins. PMID: 28536077
    5. CPEB4 and IRF4 expression in peripheral mononuclear cells are potential prognostic factors for advanced lung cancer PMID: 27113098
    6. downregulation of CPEB4 likely occurs at the late cancer stage to facilitate HCC progression. Biphasic alteration of CPEB4 expression during HCC progression suggests its complicated role in tumorigenesis PMID: 27158894
    7. positive cytoplasmic polyadenylation element binding protein 4 expression predicted a worse prognosis in glioma patients, and cytoplasmic polyadenylation element binding protein 4 could represent a useful biomarker or therapeutic target for glioma. PMID: 28381179
    8. high expression of CPEB4 was found to be an independent prognostic biomarker for overall survival in colorectal cancer patients PMID: 27771769
    9. Our studies first validated that CPEB4 interacts with Vimentin and indicated that high CPEB4 expression in astrocytic tumors correlates closely with a clinically aggressive future, and that CPEB4 might represent a valuable prognostic marker for patients with astrocytic tumors. PMID: 26546435
    10. Low CPEB4 expression and high CPEB1 expression were independent predictors of overall survival in glioma patients. PMID: 27000226
    11. findings imply that posttranscriptional deregulation of CPEB4 contributes to the inhibited cell proliferation and the enhanced cell apoptosis in colorectal cancer, and directly targeting CPEB4 by miR-203 might be a strategy in colorectal cancer treatment PMID: 26361147
    12. Evidence that CPEB4 uses both its RNA recognition motifs to maintain optimal RNA binding. PMID: 25081215
    13. CPEB4 is a candidate biomarker for defining metastatic cancers and directing personalized therapies. PMID: 24045092
    14. Knockdown of CPEB4 expression significantly facilitated HCC cell migration and invasion. PMID: 23145039
    15. CPEB4, an RNA binding protein that mediates meiotic mRNA cytoplasmic polyadenylation and translation, is overexpressed in pancreatic ductal adenocarcinomas and glioblastomas, where it supports tumor growth, vascularization and invasion. PMID: 22138752
