FIGURE 4: Analysis of Mek1 activation and localization in ndt80-arrested cells.
(A) Western blot analysis of different Mek1 phosphorylation forms in ndt80-arrested cells after 24 h in meiosis. PGK is shown as a loading control. Strains are DP424 (wild type), DP428 (zip1), DP996 (zip1 H4-K16R) and DP1002 (zip1 H4-K16Q). Two independent clones of DP966 and DP1002 were analyzed.
(B) Representative images of checkpoint-induced Mek1-GFP foci in wild type (DP584), zip1 (DP582), zip1 H4-K16R (DP1089) and zip1 H4-K16Q (DP1090) ndt80-arrested cells after 24 h in meiosis.
