Usually, receptors are proteins found on or within the membrane. Many different types of molecules can bind to receptors on the cell surface, including hormones. An insulin receptor is an example of a receptor that binds to a hormones, specifically insulin.
The insulin receptor's endogenous ligands include insulin, IGF-I and IGF-II. The binding of ligand to the Î±-chains of the IR ectodomain induces structural changes within the receptor leading to autophosphorylation of various tyrosine residues within the intracellular TK domain of the Î²-chain.
