Background: Insulin R/IGF-I R Heterotetramer

The heterotetrameric receptors for insulin (INS R) and IGF-I (IGF-I R) are receptor tyrosine kinases that consist of two ligand-binding alpha subunits and two beta subunits. Ligand binding induces autophosphorylation on multiple tyrosine residues of beta  subunits. Phosphorylation of Tyr1162 and 1163 on INS R and Tyr1135 and 1136 on IGF?I R stimulates intrinsic kinase activity.
