  • Application notes
    Is unsuitable for ICC.
  • Target

    • Function
      Its translation stimulation activity is repressed by binding to the complex CYFIP1-FMR1 (By similarity). Recognizes and binds the 7-methylguanosine-containing mRNA cap during an early step in the initiation of protein synthesis and facilitates ribosome binding by inducing the unwinding of the mRNAs secondary structures. Component of the CYFIP1-EIF4E-FMR1 complex which binds to the mRNA cap and mediates translational repression. In the CYFIP1-EIF4E-FMR1 complex this subunit mediates the binding to the mRNA cap.
    • Sequence similarities
      Belongs to the eukaryotic initiation factor 4E family.
    • Post-translational
      modifications
      Phosphorylation increases the ability of the protein to bind to mRNA caps and to form the eIF4F complex.

    Images

    • Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) analysis of human ovarian cancer tissue labelling eIF4E with ab33768 at a dilution of 1/500. Antigen retrieval was performed ab93684, Tris/EDTA buffer, pH 9. A ready to use goat anti-rabbit IgG H&L (HRP Polymer) was used as the secondary antibody. Counter stained with Hematoxylin.

      This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab33768).

    • eIF4E was immunoprecipitated from 10 µg NIH/3T3 (Mouse embryonic fibroblast) whole cell lysate with ab33768 at a 1/30 dilution. Western blot was performed from the immunoprecipitate using ab33768 at 1/1000 dilution. VeriBlot for IP Detection Reagent (HRP) (ab131366), was used for detection at 1/1000 dilution.

    • Overlay histogram showing HEK293 cells stained with ab33768 (red line). The cells were fixed with 4% paraformaldehyde (10 min) and then permeabilized with 0.1% PBS-Tween for 20 min. The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions followed by the antibody (ab33768, 1/50 dilution) for 30 min at 22ºC. The secondary antibody used was DyLight® 488 goat anti-rabbit IgG (H+L) (ab96899) at 1/500 dilution for 30 min at 22ºC. Isotype control antibody (black line) was rabbit IgG (monoclonal) (1µg/1x106 cells) used under the same conditions. Acquisition of >5,000 events was performed. This antibody gave a positive signal in HEK293 cells fixed with 80% methanol (5 min)/permeabilized with 0.1% PBS-Tween for 20 min used under the same conditions.

      This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab33768).
