The calcitonin receptor (CT) is a G protein-coupled receptor which binds the peptide hormone calcitonin and is involved in maintenance of calcium homeostasis1, particularly with respect to bone formation and metabolism 234.

CT works by activating the G-proteins Gs and Gq5.

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) 6.
