  • 功能：
    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. In addition to its role in translation initiation, also acts as a regulator of translation and stability in the cytoplasm. Component of the CYFIP1-EIF4E-FMR1 complex which binds to the mRNA cap and mediates translational repression: in the complex, EIF4E mediates the binding to the mRNA cap. Component of a multiprotein complex that sequesters and represses translation of proneurogenic factors during neurogenesis. In P-bodies, component of a complex that mediates the storage of translationally inactive mRNAs in the cytoplasm and prevents their degradation. May play an important role in spermatogenesis through translational regulation of stage-specific mRNAs during germ cell development.

    4. Lack of regulation of the interaction between the eIF4E/eIF4G subunits of the translation initiation factor complex eIF4F is a hallmark of cancer. The inhibitor 4EGI-1 binds to eIF4E, thereby preventing association with eIF4G through an allosteric mechanism.

    6. The s show that the eukaryotic translation initiation factor eIF4E, an oncoprotein, drives hyaluronan biosynthesis. eIF4E stimulates production of enzymes that synthesize the building blocks of hyaluronan, UDP-Glucuronic acid and UDP-N-Acetyl-Glucosamine, as well as hyaluronic acid synthase which forms the disaccharide chain. PMID: 29111978

    18. Mitogen-activated protein kinase interacting protein kinases (Mnks) control translation by phosphorylation of eIF4E, whereas the mTOR kinase phosphorylates/de-activates the eIF4E inhibitor, 4E-BP1, to release translational repression. PMID: 27094611
    19. Elevated levels of p-Mnk1, p-eIF4E and p-p70S6K proteins are associated with tumor recurrence and poor prognosis in astrocytomas.
