Function |
Regulates eIF4E activity by preventing its assembly into the eIF4F complex: hypophosphorylated form competes with EIF4G1/EIF4G3 and strongly binds to EIF4E, leading to repress translation. Mediates the regulation of protein translation by hormones, growth factors and other stimuli that signal through the MAP kinase and mTORC1 pathways.

Summary |
4E-BP1 (eIF4E-binding protein) also known as PHAS, is a 10-12 kDa acidic protein that compete with eIF4G for binding of eIF4E to the mRNA 5 cap structure (1). Binding of the 4E-BPs to eIF4E is reversible and is dependent on the phosphorylation status of 4E-BP1. Non-phosphorylated 4E-BP1 will bind strongly to eIF4E while, the phosphorylated form will no (2). Akt, TOR, MAP kinase, S6 kinase, and Cdc2 are known kinases capable of inactivating 4E-BP1 binding to eIF4E by phosphorylating either threonines 35, 45, 70 or serine 64. Although, not all phosphorylation events equally block the 4EBP1-eIF4E interaction (3). It has been reported previously that phosphorylation of 4E-BP1 on Thr 37 and Thr 46 is relatively insensitive to serum deprivation and rapamycin treatment, and that phosphorylation of these residues is required for the subsequent phosphorylation of a set of unidentified serum-responsive sites (4)
