Calcitonin is a peptide hormone that regulates the metabolism of calcium and phosphate. It is synthesized by the parathyroid gland, but also found in other tissues, including the pancreas, brain, and stomach. Calcitonin was first discovered as a protein in plasma membranes of chicken cells incubated with radioactive calcitonin. The plasma membranes were then collected and assayed for calcitonin protein. Binding studies showed that calcitonin binds to receptors on the surface of cells. Dose-dependent binding curves show that calcitonin has a high affinity for its receptor. Radioligand binding studies have shown that calcitonin binds to receptors in porcine membranes as well as human erythrocytes. These results indicate that calcitonin acts through G-protein coupled receptors with an affinity similar to those of other peptide hormones such as thyrotropin-releasing hormone (TRH) and glucagon.
