  • Patent number: 5905185
    Abstract: Methods for producing protein C in transgenic non-human mammals are disclosed. The protein C is modified at the two-chain cleavage site between the light and heavy chains of protein C from Lys-Arg to R.sub.1 -R.sub.2 -R.sub.3 -R.sub.4 where R.sub.1 through R.sub.4 are individually Arg or Lys. DNA segments encoding modified protein C are introduced into the germ line of a non-human mammals, and the mammal or its female progeny produces milk containing protein C expressed from the introduced DNA segments. The protein C expressed from the introduced DNA segments has anticoagulant activity when activated. Non-human mammalian embryos and transgenic non-human mammals carrying DNA segments encoding heterologous protein C are also disclosed.

  • Patent number: 5766921
    Abstract: Human protein C molecules are modified to provide increased resistance to inactivation by human plasma factors while retaining substantially the biological activity of human protein C. The modifications are generally to the heavy chain of protein C, which chain may be substituted with a protein C heavy chain of non-human origin, such as bovine, yielding a chimeric protein C molecule. The human protein C heavy chain may also be modified to be human-like, in that at least one amino acid from a non-human sequence may be substituted for the corresponding residue(s) of the human sequence, thereby allowing the molecule to retain substantially human characteristics yet having increased resistance to inactivation. Also included are methods for producing the modified protein C molecules and pharmaceutical compositions thereof.
