Sir2 suppresses the checkpoint response in the rDNA. ISA was performed on asynchronous yeast cultures of GAL-FOB1 eRFB mre11Δ (LBy-649), GAL-FOB1 mre11Δ sir2Δ (LBy-909) and GAL-FOB1 sir2Δ (LBy-888) strains. Samples were taken before galactose induction and after 90 and 180 min of induction. The kinase assay was performed as described in ‘Material and Methods’ section and in Figure 6.
