KK4A is a synthetic peptide enriched in lysine residues that confer high cationic charge and aqueous solubility. Its simple architecture supports studies of electrostatic interactions with nucleic acids and membranes. Researchers use it as a model for arginine/lysine-rich binding motifs. The peptide aids design of cell-penetrating and DNA-binding sequences.
