Cdc55 regulates sister chromatid segregation independently of Pds1 in response to DNA damage. (A) Pds1 is stabilized in cdc13–1 Δcdc55 mutants. G1-arrested cells of cdc13–1 PDS1-Myc18 and cdc13–1 Δcdc55 PDS1-Myc18 were released into YPD medium at 34°C. Crude protein extracts were prepared for Western blotting analysis. Cell-budding profile is shown in Right. (B) Mcd1 protein level is persistent in Δcdc55 mutants in the presence of DNA damage. G1 cells of cdc13–1 MCD1-HA6 and cdc13–1 Δcdc55 MCD1-HA6 were released at 34°C and withdrawn to prepare protein extracts for immunoblotting of Mcd1-HA6. The budding index is shown in Right.
