PrePPI: Predicting Protein-Protein Interactions by Combining Structural and non-Structural Information

PrePPI is a database of predicted protein-protein interactions (PPIs). PrePPI currently contains approximately 1.3 million predicted PPIs for the human proteome and predictions for additional proteomes will be released soon. Predicted interactions in the database are determined using a Bayesian framework that combines structural, functional, evolutionary and expression information.

The references indicated below provide detailed descriptions of the methods used and how the database was constructed.
