| Treatment protocol |
Cells containing inducible Ikaros were generated by transducing mouse pre-B cell line B3 with mouse stem cell virus (MSCV) retroviral vectors encoding a fusion protein of haemagglutinin-tagged wild type Ikaros (HA-Ikaros) and the estrogen receptor hormone-binding domain (ERt2), followed by an internal ribosomal entry site (IRES) and GFP. B3 cells containing inducible Ikaros (HA-Ikaros-ERt2-IRES-GFP) were plated at a density of 0.5 million cells/ml in IMDM medium containing 10% FCS and 1% penicillin-streptomycin. 0.5uM 4 hydroxy-tamoxifen was added to the cells 2h before collection.

| Extraction protocol |
B3 cells containing inducible Ikaros were plated at a density of 0.5 million cells/ml in IMDM medium supplemented with 10% FCS and 1% penicillin/streptomycin. Time point samples were collected by 5 min centrifugation at 1200 rpm. Cell pellets were washed 2 times in PBS, frozen in liquid nitrogen and storaged at -80. Control vector-ERt2 B3 cells were plated at a density of 0.5 million cells/ml in IMDM medium supplemented with 10% FCS and 1% penicillin/streptomycin. Samples were collected by 5 min centrifugation at 1200 rpm. Cell pellets were washed 2 times in PBS, frozen in liquid nitrogen and storaged at -80.
DNase-seq libraries were generatedas previously described (Myers protocol: http://myers.hudsonalpha.org/documents/Myers%20Lab%20Sequencing%20Library%20Protocol%20061508.pdf). Libraries were sequenced as 43bp paired-end on the NextSeq 500 Illumina platform. DNase-seq libraries were sequenced to a minimum depth of ~20 million reads per each biological replicate.

| Data processing |
Data were aligned to the mm10 reference using Bowtie
Capture narrow and broad chromatin elements using HOMER
Sort and merge with Bedtools software
Quantitate read counts over regions using coverageBed options (Bedtools)
Region counts were normalized with both RPKM and TMM methods
Unknown sources of variation were removed by using ARSyN method (Batch correction)
Genome_build: mm10
Supplementary_files_format_and_content: tab-delimited text files containing DHS regions for each Sample (matrix) formatted as chr_start_end (i.e. Chromosome number, Start position and End position).
