F. Percentage of RNAchIP peaks overlapping with indicated chromatin features in MEF samples from ENCODE database (green bars). Overlaps was evaluated by comparison with the list of merged peaks whose genomic location was randomized among genes with one hundred permutations (random, gray bars). Data information: Histograms represent mean and s.d. Dots represent individual data points. P-values indicate significantly higher difference between IP in HP1γ and in KO cells (***P < 0.001; two-tailed Student's t-test).
