Abstract: The present invention relates to a method for screening drug candidates for treating a disease using the interaction between calcium and phosphatidylinositol phosphate. Particularly in the present invention, it was confirmed that the concentration of calcium was increased in the obesity induced insulin resistance animal model and the increased calcium concentration inhibited the migration of Akt protein containing PH domain and the signal transduction, while the protein containing C2 domain was able to migrate to the cell membrane by binding to calcium/PIP complex even under the condition of high calcium concentration. Therefore, the investigation of the interaction between calcium and PIP can be a useful method for screening of drug candidates for treating metabolic disease, cancer or hypertension.
