Figure 3. DCAF26 is essential for histone H3K9 trimethylation.

Figure 3

(A) Dense, cauliflower-like growth patterns of dcaf26KO, cul4KO, ddb1KO, and dim-5 KO strains on plates with minimal media (30°C, 32h). (B) Growth rate of the wild-type, ku70RIP, dcaf26KO, cul4KO, ddb1KO, dim-5KO, and dim-2KO strains, measured at 25°C using the racetube assay in constant darkness. (C) Loss of histone H3K9 trimethylation at ku70RIP, ζ-η, and ψ63 regions in the dcaf26KO strain. Levels of H3K9 trimethylation at the indicated locations were determined by ChIP assay. Myc antibody was used as the negative control, and H3 antibody was used as the positive control and as the control for integrity of the nucleosome structure. (D) Western blot analysis of global H3 and H3K9 trimethylation in the wild-type strain and mutants.
