From: Identification and prediction of developmental enhancers in sea urchin embryos
ATAC-, Pol II ChIP- and PRO-seq sea urchin embryos at the SpHox11/13b locus. For ATAC- and PRO-seq, the scale in reads per million at the start of each track is maintained at the same range between states and equal between plus and minus strands. The whole region was scanned for enhancer activity by overlapping 3–5 Kb reporter constructs [24], only active CRMs are indicated, in green those active in both stages, and in gray those inactive or with unknown activity in these stages as indicated in the text
