Background: IGF1-R is a receptor tyrosine kinase which mediates actions of insulin-like growth factor 1 (IGF1). Ligand binding activates the receptor kinase, leading to receptor autophosphorylation, and tyrosines phosphorylation of substrates including, the insulin-receptor substrates (IRS1/2), Shc and 14-3-3 proteins and finally to the activation of two main signaling pathways: the PI3K-AKT/PKB pathway and the Ras-MAPK pathway. IGF1R signals also through the Janus kinase/signal transducer and activator of transcription pathway (JAK/STAT) and modulates gene transcription.
