Expression of GAL-CLA4t delays degradation of Cdc20/APC substrates with a mechanism partially dependent on Swe1. Wild-type (ySP1969), 1X GAL-CLA4t (ySP3073), swe1Δ 1X GAL-CLA4t (ySP3098), and CDC28 Y19F 1X GAL-CLA4t (ySP3074) cells expressing myc-tagged securin (Pds1myc18) were grown in YEPR, arrested in G1 with α-factor, and released in YEPRG (t = 0). Samples were collected at the indicated times for Western blot analysis (A) to score nuclear division (B) and for FACS® analysis of DNA contents (not depicted). 10 μg/ml α-factor was added back to the cultures at t = 110'.
