Cell cycle distribution of targets. Predicted targets were binned according to their expression peak in the mitotic cell cycle [20, 45]. Values on the x-axis are percentages of the whole duration of the cycle, as defined in . Beyer et al.'s  and Holloway et al.'s  predicted targets are also shown for comparison. MBF_SBF denotes targets controlled by both TFs; No_MBF_SBF refers to genes from our 445 candidates not classified as MBF or SBF targets.
