| Outline of Final Research Achievements |
Since numerous side effects of CN inhibitors are mostly caused by the diversity of the NFAT family, control of a part, not all, of the function of NFAT family members is desirable. By comparing the binding activity of CN with each NFAT, we identified a new CN-binding region into NFATc1. The CN-binding affinity of this region was much different among the NFAT family. By means of competition assay using sequential partial peptides, we determined the core peptide and essential amino acids in it. By analyzing the gene expression in NFATc4-siRNA expressing cells, and the NFATc4 promoter activity in siRNA library-transfected cells, several candidate molecules related with the selectivity among NFAT family members were identified. The molecular mechanisms useful for the regulation of a part of NFAT family members were clarified.
