Fig. 2. Cell-cycle-regulated genes affected in early cell cycle expression by perturbation of protein kinase CK2. Significantly deviating expression was defined as having at least a two-fold difference in transcription levels compared with the wildtype. (A) A Venn diagram showing numbers of deviating genes at at least one time point in the different CK2 subunit deletion strains. (B) Time point distribution of genes altered in at least one of the CK2 mutants.
