Genetic dependency of Rad55–Ser378 phosphorylation in response to a single double strand break in G1-arrested cells. Cultures of wild-type (WDHY2172) and mutant strains (WDHY2534 ddc2-Δ, WDHY2523 rad24-Δ, WDHY2511 rad50-Δ, WDHY2452 rad9-Δ, WDHY2449 mrc1-Δ) were left untreated (lanes 1), HO-endonuclease was induced (lanes 2) or the cells were treated with 0.1% MMS for 2 h (lanes 3) during G1-arrest. Rad55 was immunoprecipitated from equal amounts of cell extracts and analyzed by immunoblotting using polyclonal anti-Rad55 antibodies (left panels, panels 1–3). Rad53 was detected by immunoblotting in total cell extracts of the corresponding samples (right panels, lanes 4–6).
