Overview:
EIF4E is a eukaryotic translation initiation factor involved in directing ribosomes to the cap structure of mRNAs. EIF4E and is the rate-limiting component in protein synthesis. Overexpression of EIF4E causes malignant transformation (1). Overexpression of EIF4E in transgenic mice causes a marked increase in tumorigenesis. EIF4E is a potential physiological substrate for MNK1 and MNK2. MNK1 interacts with the EIF4F complex via its interaction with the C-terminal region of EIF4G, not through a direct interaction with EIF4E (2).
