The NuA4 complex genetically interacts with the DNA damage tolerance (DDT) pathway. (A) Schematic of the NuA4 complex. Esa1 and Yng2 are part of the smaller piccolo NuA4 complex that also includes Epl1 and Eaf6. The large NuA4 complex forms when Epl1 in piccolo interacts with Eaf1. (B) Cell survival was measured after transient exposure to increasing concentrations of MMS for 1 hr at 30° for wild type (JC470), esa1-L254P (JC2767), ubc13Δ (JC2291), esa1-L254P/ubc13Δ (JC2775), rev3Δ (JC2289), and esa1-L254P/rev3Δ (JC2771), (C) yng2Δ (JC2036), yng2Δ/ubc13Δ (JC2285) and yng2Δ/rev3Δ (JC2281), or (D) rad51Δ (JC1362), esa1-L254P/rad51Δ (JC3253) and yng2Δ/rad51Δ (JC2437). Multiple experiments (three or more) were averaged with standard deviation being reported.
