| Outline of Final Research Achievements |
ras proto-oncogene products Ras, is a member of small GTPases, which is frequently activated in a wide variety of human cancers, making them promising anti-cancer drug targets. In the present study, we determined the novel druggable pocket structure of Ras by Synchrotron X-ray crystallography utilizing Humid Air and Glue-coating (HAG) mounting method, which unveiled the molecular basis of conformational transition between the open and closed pocket structures. Molecular Dynamics simulation of the solved structures lead us to a reasonable agreement with experimental observations and the consequent scenarios on the transition. Further, crystal structure analysis of Ras/fragment-compound complex by cross-linking method gave us useful information on the structure-based design of Ras inhibitors.
