Modified coagulation factor vila with extended half-life

摘要

The present invention relates to the fields of Factor VII (FVII) and Factor Vila (FVIIa) albumin linked polypeptides. More specifically, the invention relates to cDNA sequences coding for human Factor VII and Factor Vila and derivatives genetically fused to a cDNA coding for human serum albumin which may be linked by oligonucleotides which code for intervening peptidic linkers such encoded derivatives exhibiting improved stability and extended functional plasma half-life, recombinant expression vectors containing such cDNA sequences, host cells transformed with such recombinant expression vectors, recombinant polypeptides and derivatives which do have biological activities of the unmodified wild type protein but having improved stability and prolonged shelf-life and processes for the manufacture of such recombinant proteins and their derivatives. The invention also covers a transfer vector for use in human gene therapy, which comprises such modified DNA sequences.
