CT works by activating the G-proteinsGs and Gq often found on osteoclasts, on cells in the kidney, and on cells in a number of regions of the brain.[5] 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).[6]
