Defining the Architecture of CPPs
At their core, cell-penetrating peptides (CPPs) are defined as a diverse group of short peptides, typically consisting of 4 to 40 amino acids. My exploration of cell-penetrating peptides (CPP) research reveals that these sequences act as molecular couriers. They are essentially short, positively charged peptides that excel in their ability to enter cells without compromising the integrity of the cellular membrane.
These short peptides that facilitate cellular intake and uptake of molecules are often characterized by a high content of basic amino acids, such as arginine, lysine, histidine, and ornithine. This specific chemical composition is what allows them to function as short amphipathic and cationic peptides capable of interacting with the lipid bilayer.
Mechanisms of Translocation
