IGF1R (Insulin-like Growth Factor1 Receptor) is a receptor tyrosine kinase that mediates actions of insulin-like growth factor 1 (IFG1). It binds IGF1 with high affinity and IGF2/insulin with lower affinity. Activated IGF1R is involved in cell growth and survival control. IGF1R is crucial for tumor transformation and survial of malignant cells. Ligand binding activates the receptor kinase and leads to receptor autophosphorylation and tyrosines phosphorylation of multiple substrates that function as signaling adapter proteins.
