Insulin receptorPDB ID: 2DTG
Insulin binds to the insulin receptor on the surface of cells, telling the cells to transport glucose from the blood. This structure includes the part of the receptor that binds to insulin outside of cells. The structure also includes several antibodies—they were used for the crystallization and are not important for the function of the receptor.
