    摘要: The present invention relates to a fusion protein comprising IGF-I or an IGF-I variant N-terminally linked to the C-terminus of a propeptide. The invention relates also to a method involving the use of the aforementioned fusion protein in the production of a lysine-PEGylated IGF-I or IGF-I variant. The method comprises the steps of cultivating a prokaryotic host cell comprising an expression vector containing a nucleic acid encoding the fusion protein and causing the cell to express the fusion protein, recovering and PEGylating said fusion protein, cleaving said PEGylated fusion protein with IgA protease, and recovering lysine-PEGylated IGF-I or IGF-I variant. The invention relates also to a lysine-PEGylated IGF-I or IGF-I variant produced using the above method. In addition, the invention relates to a method for treating a neurodegenerative disorders like Alzheimer's Disease using the lysine-PEGylated IGF-I or IGF-I variant and a composition comprising the lysine-PEGylated IGF-I or IGF-I variant.
