Ikaros functions as a pioneer transcription factor. a Heatmaps of Ikaros ChIP-seq, ATAC-seq, H3K4me1 and H3K27Ac ChIP-seq signals at open chromatin regions gained at day 1 vs. day 0. b Examples of de novo open chromatin regions and associated genes. Ikaros-induced epigenetic changes are shaded in gray. c Motif analysis for de novo open chromatin regions. d De novo open chromatin regions classified by function of the DNA element. e, f Gene ontology and pathway enrichment analysis of genes associated with de novo open chromatin regions
