A graphical user interface for analysis and design of protein–peptide interactions

Proteins function through interactions with other proteins or peptides, a complex process that is still not fully understood. Current research focuses on how amino acid residues interact in protein-protein or protein-peptide interactions to establish specific recognition. However, identifying key residues that are critical for binding affinity and specificity remains a challenge, and the design of specific protein-protein interaction interfaces remains a challenge for protein engineering.
