NOVEL PEPTIDE COMPLEX AND HYBRID COMPLEX THEREOF, AND USE OF SAID HYBRID COMPLEX

摘要

The present invention provides a means for delivering a substance of interest into a cell, which, even when the substance of interest is a protein, can introduce the protein into a cell with high efficiency regardless of the type of the protein, enables a given function of the protein to be exerted without inhibiting the function after the introduction of the protein into the cell, and does not use any metal that may affect a living body. A peptide complex [A] according to the present invention is characterized by comprising a leucine zipper peptide [LZ(K)] comprising the amino acid sequence represented by SEQ ID NO: 1: N'-EYQALKKKVAQLKAKNQALKKKVAQLKHK-C' or the like or a leucine zipper peptide [LZ(E)] comprising the amino acid sequence represented by SEQ ID NO: 2: N'-EYQALEKEVAQLEAENQALEKEVAQLEHE-C' or the like and an intracellular invasion peptide [CPP] linked to the leucine zipper peptide.
