The insulin receptor is a transmembrane receptor that is activated by insulin, IGF-I, IGF-II and belongs to the large class of receptor tyrosine kinase. Metabolically, the insulin receptor plays a key
Ligand-induced conformation changes in the full-length human insulin receptor reconstituted in nanodiscs. Left - unactivated receptor conformation; right - insulin-activated receptor conformation. The changes are visualized with the electron microscopy of an individual molecule (upper panel) and schematically depicted as a cartoon (lower panel).
