  • Patent number: 5441931
    Abstract: The present invention provides isolated DNA molecules comprising a DNA segment encoding a novel human amyloid protein precursor homologue and novel Kunitz-type inhibitors. Also provided are DNA constructs comprising a first DNA segment encoding a novel human amyloid protein precursor homologue or a novel Kunitz-type inhibitor wherein said first DNA segment is operably linked to additional DNA segments required for the expression for the first DNA segment, as well as host cells containing such DNA constructs and methods for producing proteins from the host cells.
    Type: Grant
    Filed: November 19, 1993
    Date of Patent: August 15, 1995
    Inventors: Cindy A. Sprecher, Donald C. Foster, Kjeld E. Norris

  • Patent number: 5358932
    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.

    Filed: September 23, 1993
    Date of Patent: October 25, 1994
    Assignee: ZymoGenetics, Inc.
    Inventors: Donald C. Foster, Richard D. Holly
  • Patent number: 5302529
    Abstract: Genomic and cDNA sequences coding for a protein having substantially the same biological activity as human protein C are disclosed. Recombinant plasmids and bacteriophage transfer vectors incorporating these sequences are also disclosed.
    Type: Grant
    Filed: April 23, 1990
    Date of Patent: April 12, 1994
    Assignee: The Board of Regents of the University of Washington
    Inventors: Donald C. Foster, Earl W. Davie
  • Patent number: 5225537
    Abstract: Methods are disclosed for producing hybrid phospholipid-binding proteins from eukaryotic cells. DNA constructs comprising a transcriptional promoter, at least one signal sequence and a hybrid phospholipid-binding protein coding sequence comprising at least one lipocortin lipid-binding domain joined to a gla-domainless, vitamin K-dependent protein and a transcriptional terminator are also disclosed.
    Type: Grant

    Date of Patent: July 6, 1993
    Assignee: ZymoGenetics, Inc.
    Inventor: Donald C. Foster
  • Patent number: 5200340
    Abstract: Zymogens of proteins having fibrinolytic activity are disclosed. The proteins are cleavable by thrombin, the cleavage resulting in the stimulation of fibrinolytic activity. Suitable proteins which may be modified in accordance with the present invention include tissue plasminogen activator, urokinase, and plasminogen variants. The modified molecules are substantially clot-specific, in view of the large amounts of thrombin associated with clots in vivo.

  • Patent number: 5073609
    Abstract: Genomic and cDNA sequences coding for a protein having substantially the same biological activity as human protein C are disclosed. Recombinant plasmids and bacteriophage transfer vectors incorporating these sequences are also disclosed.
    Type: Grant
    Filed: June 29, 1989
    Date of Patent: December 17, 1991

    Inventors: Donald C. Foster, Earl W. Davie
  • Patent number: 4968626
    Abstract: Genomic and cDNA sequences coding for a protein having substantially the same biological activity as human protein C are disclosed. Recombinant plasmids and bacteriophage transfer vectors incorporating these sequences are also disclosed.
    Type: Grant
    Filed: August 15, 1985
    Date of Patent: November 6, 1990
    Assignee: Board of Reagents of the University of Washington
    Inventors: Donald C. Foster, Earl W. Davie
  • Patent number: 4959318
    Abstract: Genomic and cDNA sequences coding for a protein having substantially the same biological activity as human protein C and recombinant transfer vectors comprising these sequences are disclosed.Methods are disclosed for producing a protein which has substantially the same biological activity as human protein C. The protein, which may be in the form of activated protein C, is produced by mammalian host cells transfected with a plasmid capable of integration in mammalian host cell DNA. The plasmid includes a promoter followed downstream by a nucleotide sequence which encodes a protein having substantially the same structure and/or activity as human protein C, the nucleotide sequence being followed downstream by a polyadenylation signal.
