PrePPI: Predicting Protein-Protein Interactions by Combining Structural and non-Structural Information
PrePPI is a database of predicted and experimentally determined protein-protein interactions (PPI) for the human proteome. Predicted interactions in the database are determined using a Bayesian framework that combines structural, functional, evolutionary and expression information. Currently, PrePPI contains 1.35 million PPIs for ~85% of the human proteome. The PrePPI database also contains experimentally determined interactions compiled from a set of publicly available databases that curate interactions from the literature, e.g., DIP, IntAct, HPRD, etc.
The references indicated below provide detailed descriptions of the methods used and how the database was constructed.
