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 G_s and G_q 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]

Interactions

Structure of human calcitonin recptor-G_s complex. The transmembrane calcitonin receptor (blue) is bound to human calcitonin (red) and the G_s complex (yellow). PDB: 7TYO ​

Calcitonin receptor has been shown to interact with Apolipoprotein B ^{[12] [13]} and LRP1. ^[14]
