Hyperglycosylated human growth hormone fusion protein and preparation method and application thereof
2016
The invention discloses hyperglycosylated human growth hormone fusion protein. The human growth hormone fusion protein sequentially contains a human growth hormone (hGH), a flexible peptide joint (L), human chorionic gonadotropin beta-carboxyl terminal rigid peptide (CTP) and a human immunoglobulin Fc fragment from the N terminal to the C terminal. The invention further discloses a method for efficiently preparing the fusion protein. Compared with a recombinant hGH, the built fusion protein has more excellent in-vivo drug efficacy, the in-vivo circulation half-life period is prolonged, the administration frequency is greatly decreased, and the bioavailability is improved; meanwhile, the production process is simpler and more efficient.
