PredUs: Prediction of Protein Interfaces Using Structural Alignment

PredUs is a method to predict protein-protein interfaces of a given monomeric query protein using its close and remote structural neighbors. Potential interfacial residues are identified by iteratively “mapping” interaction sites of each structural neighbor involved in a complex to individual residues in the query protein (see figure). Residues which frequently have interactions mapped to them are defined to be interfacial.
