NCIt definition : Insulin receptor (1382 aa, 156 kDa) is encoded by the human INSR gene. This protein
plays a role in both signal transduction and glucose homeostasis.;
NCIt note : Insulin receptor is cleaved to generate and alpha chain and a beta chain. The mature
receptor is a tetramer of 2 alpha and 2 beta chains linked by disulfide bonds. The
alpha chains contribute to the formation of the ligand-binding domain, while the beta
chains carry the kinase domain. (UniProt);
