The active N-terminal 34 residues of parathyroid hormone, made recombinantly.
Also known as: Forteo · PTH(1-34)
Part of the Foundational & therapeutic peptides cluster
Overview
Teriparatide is the first 34 amino acids of human parathyroid hormone (PTH), produced by recombinant technology and retaining the receptor-binding activity of the full hormone. It is an approved prescription drug used in bone research and osteoporosis medicine. This page is educational and not medical advice.
Source & context
Biological / chemical source: Recombinant N-terminal 1-34 fragment of human PTH
Primary research or clinical context: Prescription medicine approved in Canada and the US
Structure and origin
Full-length PTH has 84 residues, but its biological activity resides in the N-terminus. Teriparatide reproduces residues 1-34 (SVSEIQLMHNLGKHLNSMERVEWLRKKLQDVHNF), enough to activate the PTH1 receptor. It is a classic example of using a defined hormone fragment as a therapeutic peptide.
Approval and status
Sold as Forteo, teriparatide was approved by the FDA in 2002 and is likewise a prescription medicine in Canada. Because it is a scheduled drug, it is used only under medical supervision. This educational summary describes the peptide fragment and its receptor target without offering dosing or treatment recommendations.
