Outline of Final Research Achievements

This study applied previously developed PSOPIA, a method for predicting an interaction between two proteins, for developing a new computational method to predict proteins that interact with a given protein. The new method was trained on a highly imbalanced and large training dataset of human protein-protein interactions and successfully achieved higher prediction performance than PSOPIA. I have also developed a fast system that can automatically make predictions of interactions between a given protein and all the proteins registered in a public database. Furthermore, I have developed a graphical user interface with the new method developed in this study for identifying drug targets and biomarkers.
