  • Patent number: 11661464
    Abstract: A protein transduction domain and a fusion compound, which are more efficient, are proposed. As a result of selecting and testing a number of candidate peptides, the present inventors found that a GK1 peptide comprising 18 amino acids and a modified sequence obtained by replacing, adding, or deleting some sequences are bonded to high-molecular-weight materials such as proteins based on the basic sequence of the peptide, thus enabling the high-molecular-weight materials to smoothly penetrate into living bodies, for example, cells, tissues, or blood. A fusion compound, oligonucleotide, or vector using the same may be applied as a pharmaceutical composition for preventing or treating diseases.
