4E-BP1 binds to eIF4E, preventing its assembly into the EIF4F complex and inhibiting cap-dependent translation. Phosphorylation of 4E-BP1 disrupts this binding, activating cap-dependent translation. Mediates the regulation of protein translation by hormones, growth factors and other stimuli that signal through the PI3 kinase pathway. Note: This description may include information from UniProtKB.
