| Outline of Final Research Achievements |
Fpr1/FKBP12 make complex with rapamycin, a medically important immunosuppressive drug. This complex binds to and inhibits the kinase activity of TORC1, a key regulator of cellular responses to nutritional environment, thereby prohibiting a synthesis of ribosomal components. However, function(s) of Fpr1 in the natural cellular-condition without the drug has been unknown. In this study, we identified fpr1 mutation that showed synthetic lethality with the deletion mutant of HMO1 gene, which is involved in a coordinated synthesis of ribosomal components. As the results of genome wide ChIP-seq analysis and the ChIP analysis using variously modified promoters, we demonstrated that Fpr1 bound to the promoter of ribosomal protein genes dependently on Rap1, a master transcriptional regulator of those genes.
