EIF4E EIF4EL1 EIF4F Eukaryotic translation initiation factor 4E mRNA cap-binding protein eIF-4F 25 kDa subunit
Molecular Weight(MW)
25097 Da
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
Tissue Specificity
A synthetic peptide corresponding to residues in human eIF-4E, was used as immunogen. The antibody detects a band on western blot of approximately 28 kDa.
