Proteins usually do not act alone. From macromolecular machinery to antibody/antigen complexes, protein-protein interactions play an essential role in a living cell. How do proteins interact with each other? High resolution structures of protein-protein complexes provide valuable insights into the mechanisms of protein-protein interactions. Structural comparison of protein-protein interfaces further facilitates studies of protein-protein interaction modes and helps to infer relationship between proteins. iAlign is a program designed for the comparison of the structures of protein-protein interfaces.
Details of the program can be found in the following references:
