20080260755 | Proteolytically cleavable fusion proteins with high molar specific activity - The invention relates to therapeutic fusion proteins in which a coagulation factor is fused to a half-life enhancing polypeptide, and in which both are connected by a linker peptide that is proteolytically cleavable. The cleavage of such linkers liberates the coagulation factor from activity-compromising steric hindrance caused by the half-life enhancing polypeptide and thereby allows the generation of fusion proteins may show relatively high molar specific activity when tested in coagulation-related assays. Furthermore, the fact that the linker is cleavable can enhance the rates of inactivation and/or elimination after proteolytic cleavage of the peptide linker compared to the rates measured for corresponding therapeutic fusion proteins linked by the non-cleavable linker having the amino acid sequence GGGGGGV. | 10-23-2008 |
