ChIP assay.Relative enrichment was measured by a ratio ofP1-rrtoP1-wwof % input, which was calculated as a percentage of DNA amount in a fraction of chromatin immuno-precipitation by anti-P1 antibody to total DNA amount in an input fraction. Error bar indicates standard error taken from three independent ChIP experiments. Asterisk showsP < 0.05 (t-test).
