Research Areas

Small molecular ligands with unique activities must have the specific target molecules that exist in their cells or organisms. Identification of the target molecules is critical for elucidating the mode of action of the molecular ligands and for drug development. However, drug target identification has been difficult in general, because the mode of interactions between the molecular ligands and their targets is not uniform. Our team aims at developing innovative techniques based on global analysis of yeast genetic interaction and physical interaction using mass spectrometry, which leads to quick and accurate detection of the ligand-target interactions. Furthermore, novel assay systems for mode-of-action studies based on protein post-translational modifications and epigenetics will be established.
