Background Information

IGF1R, also named CD221, belongs to the protein kinase superfamily, Tyr protein kinase family, and INS receptor subfamily. IGF1R binds INS-like growth factor 1 (IGF1) with a high affinity and IGF2 with a lower affinity. It has a tyrosine-protein kinase activity, which is necessary for the activation of the IGF1-stimulated downstream signaling cascade. When present in a hybrid receptor with INSR, IGF1R binds IGF1. The hybrid receptors composed of IGF1R and INSR isoform Long are activated with a high affinity by IGF1, with low affinity by IGF2, and not significantly activated by INS, and that hybrid receptor composed of IGF1R and INSR isoform Short are activated by IGF1, IGF2, and INS. In contrast, the hybrid receptors composed of IGF1R and INSR isoform Long and hybrid receptors composed of IGF1R and INSR isoform Short have similar binding characteristics, both bind IGF1 and have a low affinity for INS. Defects in IGF1R may be a cause in some cases of resistance to INS-like growth factor 1 (IGF1 resistance).
