When cancer cells are treated with the peptide and the pharmaceutical composition containing the same, the peptide can specifically bind to CP2c by passing, with very high stability, through the cell membrane and can inhibit the DNA binding ability of CP2c, thereby disturbing CP2c-mediated cancer cell-specific transcriptional activity through the inhibition of CP2c activity. Thus, the peptide and pharmaceutical composition containing the same can be effectively used for specifically treating only cancer cells and can be utilized for cancer prevention and as a dietary supplement additive therefor.
