    摘要: Human recombinant G-CSF (hr-G-CSF), an mRNA fraction encoding hr-G-CSF, a DNA sequence encoding hr-G-CSF, modified DNA sequences encoding hr-G-CSF, that are expressed at high levels in recombinant hosts are disclosed. Modifications to the 5' DNA sequence encoding mature mG-CSF are also disclosed. The modifications to the third position nucleotide of at least one in the 5' region codon of the DNA sequence of G-CSF result in enhanced expression of mG-CSF protein in recombinant host cells, without changing the amino acid sequence of the protein. Other modifications yield muteins of G-CSF in which the NH 2 -terminal amino acid is not methionine when produced from a recombinant host cell. Expression vectors carrying the altered mG-CSF DNA sequence are disclosed and claimed.

    摘要: Novel plasminogen activators are disclosed. Of the novel plasminogen activators, one is a modified urokinase that is altered to make it less susceptible to forming two chain-urokinase and to increase the fibrin specificity of urokinase. Also among the novel plasminogen activators are fibrinolytic proteins comprised of at least one domain capable of interacting with fibrin and the protease domain of urokinase. The domain capable of interacting with fibrin may have an amino acid sequences substantially the same as those of kringle-2 of t-PA, kringle-1 and/or -4 of plasminogen and the finger domain of t-PA. The protease domain may have an amino acid sequence substantially the same as that of 30 Kd urokinase. DNA sequences encoding the novel plasminogen activators, expression vectors and expression systems therefor are also disclosed and claimed.
