  • Patent number: 6706496
    Abstract: Compositions and methods for expression of heterologous mammalian proteins and their secretion in the biologically active mature form using a yeast host cell as the expression system are provided. Compositions of the invention are nucleotide sequences encoding a signal peptide sequence for a yeast secreted protein, an optional leader peptide sequence for a yeast secreted protein, a native propeptide leader sequence for a mature protein of interest, and a sequence for the mature protein of interest, all operably linked to a yeast promoter. Each of these elements is associated with a processing site recognized in vivo by a yeast proteolytic enzyme. Any or all of these processing sites may be a preferred processing site that has been modified or synthetically derived for more efficient cleavage in vivo. The compositions are useful in methods for expression of heterologous mammalian proteins and their secretion in the biologically active mature form.

  • Patent number: 6692907
    Abstract: The hypervariable region (E2HV) of the putative hepatitis C virus (HCV) glycoprotein E2/NS1, between about amino acid 384 to about amino acid 414, is a rapidly evolving region of HCV, and is likely to be under positive immune selection. A newly discovered motif within this hypervariable region is immunogenic and conserved with respect to the character of the amino acids. In many isolates, this motif falls between amino acids 401 to 406 or 407. The discovery of this motif allows for additional materials and methods to treat and diagnose HCV.
