| Outline of Final Research Achievements |
The purpose of this study is to efficiently search for peptide targets, which is considered important in middle molecule drug discovery, and to develop a prediction method reveals binding target.
I have performed large-scale parallelization to predict protein-protein interactions based on three-dimensional structure information. In addition, an all-to-all prediction was performed on representative human protein structures, and an web-interface was constructed to find the prediction results via a web browser. In addition, I have developed computational methods that conducting binding analysis of peptide molecules and proteins, LIK method which is a molecular target prediction method based on bipartite graph prediction by machine learning, and another molecular target prediction method named PKRank based on learning-to-rank.
