Protein found in humans
The calcitonin receptor (CT ) is a G protein-coupled receptor that binds the peptide hormone calcitonin and is involved in maintenance of calcium homeostasis ,[ 5] particularly with respect to bone formation and metabolism.[ 6] [ 7] [ 8]
CT works by activating the G-proteins Gs and Gq often found on osteoclasts, on cells in the kidney, and on cells in a number of regions of the brain.[ 9] It may also affect the ovaries in women and the testes in men.
The function of the CT receptor protein is modified through its interaction with Receptor activity-modifying proteins (RAMPs), forming the multimeric amylin receptors AMY1 (CT + RAMP1), AMY2 (CT + RAMP2), and AMY3 (CT+ RAMP3).[ 10]
Preclinical studies have suggested that dual amylin and calcitonin receptor agonists may be more effective than amylin receptor agonists for obesity and type II diabetes .[ 11]
