Distribution of total Pol II or its phosphorylated forms in RNAi COMPASS subunit-knockdown lines.

1The average of the ChIP-PCR values ± SD, n = 4, for wdr5R1, wdr5R2, ash2R7, and ash2R16 RNAi knockdown lines, as a percent of wild type. The 5′ and 3′-end regions correspond to regions 2 and 6 in Figure 2; for the shorter LTP7 gene the 3′ end corresponds to region 3. P-values are for the significance of the differences between the 5′-end and 3′-ends.
