Calcitonin is a hormone that plays a role in regulating the level of calcium in your blood by decreasing it. The C-cells in your thyroid gland produce calcitonin.

Calcitonin is formed by the proteolytic cleavage of a larger prepropeptide, which is the product of the CALC1 gene (CALCA). It is functionally an antagonist with PTH and Vitamin D3.

Calcitonin is a hormone produced by the thyroid gland, a butterfly-shaped organ located at the front of your neck. This hormone plays a vital role in regulating calcium levels in the body and serves as an …
