eIF4EBP1 is a member of a family of translation repressor proteins. The protein directly interacts with eukaryotic translation initiation factor 4E (eIF4E), which is a limiting component of the multisubunit complex that recruits 40S ribosomal subunits to the 5' end of mRNAs. Interaction of this protein with eIF4E inhibits complex assembly and represses translation. This protein is phosphorylated in response to various signals including UV irradiation and insulin signaling, resulting in its dissociation from eIF4E and activation of mRNA translation.
eIF4EBP2 regulates eIF4E activity by preventing its assembly into the EIF4F complex. It mediates the regulation of protein translation by hormones, growth factors and other stimuli that signal through the MAP kinase pathway. Nonphosphorylated EIF4EBP2 interacts with EIF4E.
eIF4EBP2 is phosphorylated on serine and threonine residues in response to insulin, EGF and PDGF, and belongs to the eIF4E binding protein family.
eIF4EBP3 is a member of the EIF4EBP family which derives it name from proteins that bind to eukaryotic initiation factor 4E and that prevent its assembly into EIF4F. Cotranscription of this gene and the neighboring upstream gene (MASK) generates a transcript (MASK-BP3) which encodes a fusion protein comprised of the MASK protein sequence for the majority of the protein and a different C terminus due to an alternate reading frame for the EIF4EBP3 segments.
