L17E is an attenuated cationic amphiphilic lytic peptide that facilitates the delivery of macromolecules, including proteins, antibodies, and DNA nanostructures. Its mechanism involves membrane insertion and cleavage via electrostatic interactions, promoting intracellular escape. The effectiveness of L17E is closely linked to the expression of KCNN4, encoding the calcium-activated potassium channel KCa3.1, and it enhances cellular uptake through the induction of micropinocytosis. Additionally, L17E can be optimized through dimerization and combined with other delivery systems, such as nuclear localization signal peptides and cell membrane-coated nanoparticles, for improved performance in research applications.
