Total number of genomic intervals	7,054	590*
Total number of base pairs	2,116,200	858,180
Regions overlap with at least one locus	83.5%	63.9%
Regions overlap with at least one exon	62.9%	34.4%
Regions overlap with at least one intron	65.2%	59.5%
Regions overlap with promoters	67.7%	30.8%

The ChIP-Seq data of this study are based on five established BL cell lines, the ChIP-PET data of Zeller and colleagues were produced by analysis of the model cell line P493-6 [24].

*A total of 590 regions were checked ( = 100%), 3 regions were skipped for overlap analysis (>10,000 bp).
