Calcitonin Receptor Information

The calcitonin receptor (CT) is a G protein-coupled receptor that binds the peptide hormone calcitonin and is involved in maintenance of calcium homeostasis[1], particularly with respect to bone formation and metabolism [2][3][4].

CT works by activating the G-proteins Gs and Gq[5].

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].

Interactions

Calcitonin receptor has been shown to interact with Apolipoprotein B[7][8] and LRP1.[9]
