靶标

  • 功能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.
  • 序列相似性Belongs to the eukaryotic initiation factor 4E family.
  • 翻译后修饰Phosphorylation increases the ability of the protein to bind to mRNA caps and to form the eIF4F complex.

  • Anti-eIF4E antibody (ab1126) + 30ug bovine kidney extract

    Predicted band size : 25 kDa
    Observed band size : 28 kDa (why is the actual band size different from the predicted?)
  • ab1126 at 1/100 staining human epithelial cells by ICC/IF. The cells were paraformaldehyde fixed and blocked with BSA prior to incubation with the antibody for 1 hour. An Alexa-Fluor ® 647 conjugated goat anti-rabbit IgG was used as the secondary.

    See Abreview

  • IHC image of ab1126 staining in human breast carcinoma formalin fixed paraffin embedded tissue section, performed on a Leica BondTM system using the standard protocol F. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20 mins. The section was then incubated with ab1126, 1/1000 dilution, for 15 mins at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX.

    For other IHC staining systems (automated and non-automated) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times.
