[Problem] The purpose of the present invention is to provide a cell-permeable peptide that exhibits a higher selective toxicity for a target cell. Another purpose is to provide a cell-permeable peptide that functions as an active agent delivery carrier. [Solution] An isolated cell-permeable peptide that contains a motif selected from the group consisting of RGN, RGH, RYN, LYN, FFN, and QYN, and a motif selected from the group consisting of NGR, SEQ ID NO: 44, and SEQ ID NO: 45, and that has a β-strand structure between these respective motifs. |
