Summary of HoxB4 ChIP-Seq binding peaks at 3 stages of ESC differentiation to hematopoietic cells. (A) Venn diagram of the HoxB4 ChIP-Seq peaks from day 6 (D6), 16 (D16), and 26 (D26) cells. (B) Distribution of the distance between HoxB4 peak center and nearest RefSeq transcription start site (TSS). Distance is shown in log scale of base 10. Red dashed line shows the median distance. (C) Genomic distribution of HoxB4 peaks. (D) HoxB4 DNA-binding motif identified by a motif search using the top 500 HoxB4 peaks (ranked by ChIP-Seq enrichment ratio) from day 6 cells.
