| peptide-protein complex | Protein-peptide interaction (PPI) is one of the most important biological interactions and plays a vital role in many diseases including cancer. Therefore, the understanding of PPI provides valuable insights for all cellular processes, functional mechanisms and peptide drug discovery. The PPI can be analyzed by the study of the protein-peptide complex structures. However, only a small part of them has a known complex structure, and the experimental determination of PPI is expensive and inefficient. |
