Biochem/physiol Actions
Hypocalcemic hormone produced by the parafollicular C cells of the thyroid or by the ultimobranchial bodies of nonmammalian vertebrates. Decreases blood calcium and phosphate due to inhibition of resorption by osteoblasts and osteocytes.
Other Notes
32 amino acid polypeptide, 8 of which are conserved across all species.
