Amino Acid Sequence
Cys-Ser-Asn-Leu-Ser-Thr-Cys-Val-Leu-Gly-Lys-Leu-Ser-Gln-Glu-Leu-His-Lys-Leu-Gln-Thr-Tyr-Pro-Arg-Thr-Asp-Val-Gly-Ala-Gly-Thr-Pro-NH2 [Disulfide bridge: 1–7]
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
A 32 amino acid polypeptide, 8 of which are conserved across all species.
