4E-BP1 (human)

Overview 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. Protein type: Translation; Translation initiation Cellular Component: protein complex; cytoplasm; nucleolus; cytosol; nucleus Molecular Function: protein binding; eukaryotic initiation factor 4E binding Biological Process: negative regulation of translational initiation; cellular protein metabolic process; TOR signaling pathway; translation; translational initiation; insulin receptor signaling pathway; gene expression; positive regulation of mitotic cell cycle; negative regulation of protein complex assembly; G1/S transition of mitotic cell cycle Reference #:  Q13541 (UniProtKB) Alt.
