Eukaryotic translation initiation factor 4E-binding protein 1
Phosphorylated heat- and acid-stable protein regulated by insulin 1
機能Regulates eIF4E activity by preventing its assembly into the eIF4F complex. Mediates the regulation of protein translation by hormones, growth factors and other stimuli that signal through the MAP kinase and mTORC1 pathways.
配列類似性Belongs to the eIF4E-binding protein family.
翻訳後修飾Phosphorylated on serine and threonine residues in response to insulin, EGF and PDGF. Phosphorylation at Thr-37, Thr-46, Ser-65 and Thr-70 is regulated by mTORC1. Phosphorylated upon DNA damage, probably by ATM or ATR.
