Differential occupancy by Pol III in various cell types.

<p><b>A.</b> Venn diagram showing intersection of Pol III-bound annotated genes in four different cell types, H1 (red), HeLa (cyan), Human Foreskin Fibroblasts - HFF (green) and HEK293T cells (blue). <b>B–D.</b> Pol III QValFDR tracks at example tDNAs that are differentially bound in H1 cells (red) compared to HeLa (cyan) and HEK293 (blue) cells. Arrows mark the genes that differ in Pol III occupancy. Asterisks mark the tDNAs that are similarly occupied in all the cell types. The axes are as described in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0085648#pone-0085648-g001" target="_blank">Figure 1</a>. <b>E–G.</b> Pol III QValFDR tracks at example Type II (<b>E</b>) and Type III (<b>F,</b>G) loci that are similarly bound in the three cell types. Asterisks mark the genes that are bound by Pol III in all cell types.
