Ubc4 is required in the nucleus for tolerance to hydroxyurea. (A) Successive 10-fold dilutions of ABy448 (W303-1a), ABy607 (ubc4Δ), ABy662 (UBC4-NES-3HA), ABy597 (not4Δ), ABy764 (ubc5Δ), ABy013 (mcm10-1), ABy342 (mcm10-1, ubc4Δ), ABy455 (mcm10-1, UBC4-NES-3HA), ABy529 (mcm10-1, not4Δ), and ABy363 (mcm10-1, ubc5Δ) were grown for 3 d at 30°C on YPD plates and YPD containing 50 mM, 100 mM, and 200 mM HU. (B) Asynchronous cultures of ABy597 (not4Δ) and ABy529 (mcm10-1, not4Δ) were grown to midlog phase. Cdc17–3HA and α-tubulin were analyzed by Western blot in undiluted extracts and extracts diluted 10-fold, 25-fold, and 50-fold.
