Effect of Tbf1 and Rap1 cotethering on MRX association with nearby DNA ends. LacO8-TetO4-HO (KSC2863) and LacO8-TetO4-HO rif1Δ rif2Δ (KSC2864) cells expressing Mre11-myc and Tel1-HA were transformed with placI-TBF1, ptetR-RAP1, or the control vector, together with the GAL-HO plasmid. Cells were analyzed for Mre11 binding or Tel1 binding by ChIP assay as in Figure 1B. The LacO8-TetO4-HO construct is shown in Figure 4A. The strains used here contained a sir2Δ mutation to suppress inefficient HO cleavage resulting from Rap1 tethering nearby (Hirano et al., 2009).
