The interactions between ATP-dependent chromatin remodeling and covalent modification of histones. (A) Rows represent ATP-dependent chromatin remodelers, and columns represent histone modifications. Ac represents acetylation, while me indicates methylation (e.g. me2 indicates dimethylation). For each remodeler-modification pair, if it satisfies P < 0.05 in both statistical tests, it was colored red (positive regulation by the remodeler) or green (negative regulation by the remodeler), otherwise it was colored white. (B) The correlation between transcriptional activity  and modification enrichment at promoters for the histone modification indicated in each column. Colors indicate Pearson correlation coefficients.
