title: Membrane permeability commonly shared among arginine-rich peptides.
abstract: Delivery of proteins and other macromolecules using membrane-permeable carrier peptides is a recently developed novel technology, which enables us to modulate cellular functions for biological studies with therapeutic potential. One of the most often used carrier peptides is the arginine-rich basic peptide derived from HIV-1 Tat protein [HIV-1 Tat (48-60)]. Using this peptide, efficient intracellular delivery of molecules including proteins, oligonucleic acids and liposomes has been achieved. We have demonstrated that these features were commonly shared among many arginine-rich peptides such as HIV-1 Rev (34-50) and octaarginine. Not only the linear peptides but also branched-chain peptides showed efficient internalization with an optimum number of arginines (approximately eight residues). The structural and mechanistic features of the translocation of these membrane-permeable arginine-rich peptides are reviewed.
