PEPTIDES IMPARTING CELL PERMEABILITY TO LIPID MEMBRANE STRUCTURE AND/OR ENHANCING CELL PERMEABILITY OF LIPID MEMBRANE STRUCTURE, AND LIPID MEMBRANE STRUCTURE COMPRISING LIPID BOUND TO SUCH PEPTIDE AS CONSTITUENT LIPID AND HAVING CELL PERMEABILITY OR SHOWING ENHANCED CELL PERMEABILITY

摘要

Provided are peptides imparting cell permeability to a lipid membrane structure and/or enhancing the cell permeability of a lipid membrane structure, and a lipid membrane structure which comprises, as a constituent lipid, a lipid bound to such a peptide and has cell permeability or shows enhanced cell permeability. The amino acid sequences of the peptides imparting cell permeability to a lipid membrane structure and/or enhancing the cell permeability of a lipid membrane structure are represented by: LX1X2X1X1X1L, LLX2X1X1X1L and LX1X2X1X1L (wherein L represents a leucine residue; X1 represents a polar amino acid residue; and X2 represents a polar, non-charged and branched chain amino acid residue).
