1JQH - PubMed Abstract: 
The insulin-like growth-factor-1 (IGF-1) receptor, which is widely expressed in cells that have undergone oncogenic transformation, is emerging as a novel target in cancer therapy. IGF-1-induced receptor activation results in autophosphorylation of cytoplasmic kinase domains and enhances their capability to phosphorylate downstream substrates. Structures of the homologous insulin receptor kinase (IRK) exist in an open, unphosphorylated form and a closed, trisphosphorylated form.
