  • Interferon-? (IFN-?) fused proteins comprising IFN-? and a cytoplasmic transduction peptide (CTP)
    Patent number: 8623348
    Abstract: Disclosed is an interferon-? (IFN-?) fused protein having IFN-? fused to a cytoplasmic transduction peptide (CTP). The disclosure relates to a fused protein wherein a CTP, which binds well to cell-membrane barriers and enables translocation into the liver, is genetically fused to a human IFN-?, thereby enhancing the conjugation capacity of cell membranes and antiviral activity, inhibiting CTP transport into the cell nucleus, and enhancing the translocation and settlement of the fused protein into the liver and of transduction to the liver tissue. Accordingly, it is possible to develop protein-based medicines effective for preventing or treating various liver diseases associated with viral infection at low doses.
    Type: Grant
