eIF4E, a protein modulates translation of maternal mRNAs in early embryos before the onset of zygotic transcription. eIF4E also influences the overall rate of translation. eIF4E binds to the 7 methyl GTP cap structure of eukaryotic mRNAs. Phosphorylation of eIF4E on serine 209 regulates the affinity of this protein for the 7 methyl GTP cap and/or RNA. Phosphorylation also enhances the interaction of eIF4E with eIF4G, which form a complex known as eIF4F. eIF4E phosphorylation is correlated with increased translational rate in a number of cell types. Several kinases are currently being investigated as potential regulators of eIF4E including PKC and/or the MAP kinase activated Mnk.
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. Subunit: eIF4F is a multi-subunit complex, the composition of which varies with external and internal environmental conditions. It is composed of at least EIF4A, EIF4E and EIF4G1/EIF4G3. EIF4E is also known to interact with other partners. The interaction with EIF4ENIF1 mediates the import into the nucleus. Nonphosphorylated EIF4EBP1, EIF4EBP2 and EIF4EBP3 compete with EIF4G1/EIF4G3 to interact with EIF4E; insulin stimulated MAP-kinase (MAPK1 and MAPK3) phosphorylation of EIF4EBP1 causes dissociation of the complex allowing EIF4G1/EIF4G3 to bind and consequent initiation of translation. Rapamycin can attenuate insulin stimulation, mediated by FKBPs. Interacts mutually exclusive with EIF4A1 or EIF4A2. Interacts with NGDN and PIWIL2. Component of the CYFIP1-EIF4E-FMR1 complex composed of CYFIP, EIF4E and FMR1. Interacts directly with CYFIP1 (By similarity). Interacts with Lassa virus Z protein. Binds to MKNK2 in nucleus. Interacts with LIMD1, WTIP and AJUBA. Subcellular Location: Cytoplasm, P-body. Post-translational modifications: Phosphorylation increases the ability of the protein to bind to mRNA caps and to form the eIF4F complex. Similarity: Belongs to the eukaryotic initiation factor 4E family.

核細胞翻譯起始因子4E-EIF4E是蛋白合成的一個主要調控因子，它表達量增加會促進多種腫瘤的生長的增值、分化，因此EIF4E是一種非常重要的抗癌藥物靶標。eIF-4E是一種涉及核糖體與mRNA帽子結構結合的真核生物翻譯起始因子。它以2種形式存在：游離形式（25kDa）和作為多蛋白復合物eIF-4F的一個組分。 eIF-4E 是數量最少的一種起始因子，涉及翻譯起始的限速步驟，磷酸化調節蛋白質的生物合成。 |
