    • The present invention relates to modified cDNA sequences coding for vitamin K-dependent polypeptides, in particular human Factor VII, human Factor VIIa, human Factor IX and human protein C and their derivatives with improved stability and extended 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 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.
    • 本发明涉及编码维生素K依赖多肽,特别是人因子VII,人因子VIIa,人因子IX和人蛋白C及其衍生物的修饰cDNA序列,其具有改善的稳定性和延长的血浆半衰期,含有这样的重组表达载体 cDNA序列,用这种重组表达载体转化的宿主细胞,确实具有未修饰的野生型蛋白质的生物活性但具有改进的稳定性的生物活性的重组多肽和衍生物,以及制备这些重组蛋白及其衍生物的方法。 本发明还涵盖用于人基因治疗的转移载体,其包含这种修饰的DNA序列。
