Overexpression of Recombinant Human Teriparatide rhPTH (1–34) in Escherichia coli : An Innovative Gene Fusion Approach

摘要

Background:Parathyroid hormone is an 84-amino acid peptide secreted by the parathyroid glands. Its physiological role is maintenance of normal serum calcium level and bone remodeling. Biological activity of this hormone is related to N-terminal 1–34 amino acids. The recombinant form of hormone (1–34) has been approved for treatment of osteoporosis from 2002. In this study, a novel fusion partner has been developed for preparation of high yield recombinant 1–34 amino acids of hPTH.
