    摘要: Provided is a screening method for a more effective Ras inhibitor. Further provided are amino acid residues at a site important for an interaction with a Ras inhibitor in a Ras polypeptide. By confirming a difference between structural information on the Ras polypeptide by NMR and structural information between a complex of the Ras polypeptide and a seed compound by NMR, a more effective lead compound than the seed compound can be selected. As a result of analysis based on the structural information on the Ras polypeptide by NMR, the amino acid residues capable of interacting with a Ras inhibitor candidate (a) are K5, E37, D38, S39, L56, E63, Y64, A66, M67, Q70, Y71, R73, and T74 with reference to an amino acid sequence set forth in SEQ ID NO: 1.
