Introduction #

MLCPP (machine learning cell-penetrating peptides) is a two-layer machine learning method to predict the cell-penetrating peptides (CPPs) from the given peptides. In first layer, it predicts CPPs and in second layer, it predict the uptake efficiency of peptides. In first layer, the extremely randomized tree (ERT) performing well, and in second layer, the random forest performing well. CPPs are typically 5 to 30 amino acids in length and can pass through cell membranes via energy-dependent and -independent mechanisms without specific receptor interaction. CPPs can transport to the inside of cells while carrying a wide variety of covalently or non-covalently linked cargo, including nanoparticles, peptides, proteins, antisense oligonucleotides, small-interfering RNA, double-stranded DNA, and liposomes. Interestingly, pre-clinical evaluations of CPP-derived therapeutics showed promising results in various disease models, which subsequently translated into clinical trials. Therefore, CPPs represent an effective approach for delivering bioactive molecules into cells for various biomedical applications.
