Disclosed are a cell-permeable p53 recombinant protein in which a macromolecule transduction domain (MTD) is fused to the tumor suppressor p53, a polynucleotide encoding the same, a recombinant expression vector for producing the same, and a pharmaceutical composition of the treatment of cancer, comprising the same. Having high cell permeability, the p53 recombinant protein is effectively transduced into cells so that the tumor suppressor p53 can be translocated into cell nuclei. Within nuclei, p53 inhibits the formation of cyclin-CDK complexes to halt the cell cycle, thus suppressing excessive cell proliferation and inducing apoptosis of tumor cells. Therefore, the p53 recombinant protein can be useful as an anticancer agent in the treatment of various cancers. |
