    摘要: An object of the present invention is to provide a co-crystal of a Ras polypeptide which adopts a conformation having a pocket on the molecular surface of Ras and GTP or a GTP analog, a production method for the crystal, and a screening method for a Ras function inhibitor based on information about the conformation obtained by X-ray crystallographic analysis using the crystal. The object is achieved by focusing on a mutation which adopts a conformation having a pocket on the molecular surface of Ras, acquiring a mutant Ras polypeptide having introduced therein such mutation, producing a co-crystal of the mutant Ras polypeptide and a GTP analog, and further subjecting the co-crystal to X-ray crystallographic analysis to acquire structural information about the conformation including information about the structure surrounding the pocket.
