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
modificationsPhosphorylation increases the ability of the protein to bind to mRNA caps and to form the eIF4F complex. - Information by UniProt

Western blot - Anti-eIF4E antibody (ab1126)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?
Western blot of 30µ g bovine kidney extract with anti-eIF-4E (GLO153). The arrow denotes the position corresponding to eIF-4E (~ 28 kDa). -
Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-eIF4E antibody (ab1126)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.
