IF4E protein plays multiple roles in cells, regulating processes such as protein synthesis, mRNA export, RNA processing and splicing. As part of the eIF4F protein complex, IF4E recognizes the mRNA cap and promotes ribosome binding. It is also involved in translation repression and regulation of mRNA stability. In P bodies, IF4E is involved in storing translationally inactive mRNA. In addition, IF4E also plays a role in spermatogenesis, neurogenesis, and mRNA nuclear-cytoplasmic transport. The ability of IF4E to participate in mRNA export relies on binding to the m7G cap and the EIF4E-sensitive element (4ESE) . LRPPRC promotes the formation of EIF4E-dependent mRNA export complexes. The action of IF4E changes the composition of nuclear pores and promotes the nuclear export of specific mRNAs. EIF4E Protein, Human is the recombinant human-derived EIF4E protein, expressed by E. coli , with tag free.
