The invention relates to a transdermal peptide with a nuclear localization ability and having an amino acid sequence as shown in SEQ ID NO: 1. The invention provides a fusion protein with a nuclear localization ability, which comprises a macromolecular protein with one end being linked to the transdermal peptide. The invention also discloses the use of the transdermal peptide in the preparation of a medicament or a transdermal preparation for treating skin diseases. The invention further provides a medicament for treating a skin disease, comprising the transdermal peptide and a pharmaceutically acceptable excipient. The transdermal peptide enters the cells autonomously to locate in the nuclei, and can penetrate through the stratum corneum of the skin into cells in the dermis. The peptide is conveniently synthesized artificially and suitable for transdermal administration, and has a therapeutic potential via transdermal administration by carrying a drug for treating skin diseases. 1. A transdermal peptide with a nuclear localization ability , having an amino acid sequence as shown in SEQ ID NO: 1 , wherein the transdermal peptide enters the eukaryotic cells autonomously.2. The transdermal peptide according to claim 1 , wherein the transdermal peptide is further linked to fluorescein.3. The transdermal peptide according to claim 2 , wherein the fluorescein is fluorescein isothiocyanate claim 2 , rhodamine or carboxyfluorescein (FAM).4. The transdermal peptide according to claim 1 , wherein the eukaryotic cells are HaCaT cells claim 1 , WS1 cells claim 1 , TE-1 cells claim 1 , Eca-109 cells claim 1 , or HeLa cells.5. A fusion protein with a nuclear localization ability claim 1 , comprising a macromolecular protein claim 1 , one end of which is linked to the transdermal peptide according to .6. The fusion protein with a nuclear localization ability according to claim 5 , wherein the other end of the macromolecular protein is linked to a fluorescent protein.7. The fusion ...
