RT Journal Article SR Electronic T1 Fusion Polypeptides That Inhibit Exocytosis: Fusing Aptamer and Cell-Penetrating Peptide Technologies and Pharmacologies JF Molecular Pharmacology JO Mol Pharmacol FD American Society for Pharmacology and Experimental Therapeutics SP 980 OP 982 DO 10.1124/mol.105.011429 VO 67 IS 4 A1 Lee E. Eiden YR 2005 UL http://molpharm.aspetjournals.org/content/67/4/980.abstract AB Cell-penetrating peptides are amphipathic or cationic oligopeptides able to transport covalently attached cargoes across cell membranes. Peptide aptamers are polypeptide fragments of endogenous proteins that mimic and thus perturb interactions with other cellular proteins. Combining aptamer and CPP technology can generate pharmacological reagents effective in cell culture models and in vivo.
