The invention belongs to the field of biomedicine and relates to a human original cell permeable peptide hPP3 and usage thereof. The cell permeable peptide hPP3 provided by the invention has a cell membrane permeation function, thereby being capable of carrying such large molecules as protein to enter a plurality kind of cells in a transmembrane manner; since the peptide segment is derived from human protein, the possibility of causing human body immune response is small, the potential insecurity factors are relatively small, so that the hPP3 can serve as a transmembrane transport carrier having brilliant development prospect of such bioactive molecules as protein, polypeptide, and the hPP3 can be used as an intracellular drug transport carrier. |
