| Extraction protocol |
Flash-frozen minced tissue was thawed in cell culture medium (Gibco® Keratinocyte-SFM (1X) Catalog #17005-042) with 1% formaldehyde for 10 minutes under rotation for cross-linking, which was then quenched with 2M Glycine (final concentration of 100mM). Minced tissue was then washed twice with ice-cold PBS with Protease Inhibitor Cocktail (PIC) and resuspended in 1mL ChIP Lysis Buffer (1% SDS, 50mM Tris HCl pH 8.1, 10mM EDTA) with PIC. The suspension was ground in a dounce homogenizer 10-15 times and then passed through a 40µM filter and checked for lysis with Trypan Blue under a microscope. The nuclei were then sonicated using a probe sonicator (Branson Sonifier® Cell Disruptor 185, 4.5 Output Control, 12 cycles, 10 seconds ON/30 seconds OFF) and centrifuged at 12,000rpm for 10 minutes at 4°C.
Libraries were constructed using the KAPA DNA library preparation kit (KK8230)

| Data processing |
Basecalls performed using CASAVA version 1.8.2
Sequencing reads were aligned to hg19 using BWA-0.6.2
Data were filtered by removing nonuniquely mapping reads and PCR duplicates
ChIP-seq reads were extended to sequencing library’s mean fragment size, estimated using the default setting of HOMER v.4.3’s makeTaqDirectory command
Each data set was normalized into a single value for each genomic position using the Wiggler tool with default settings and “globalmap_k20tok54” as the mappability parameter
Mean Wiggler values were calculated in 10-bp bins, and Z-score transformation by subtracting the mean Wiggler value across the genome and dividing by the standard deviation of the genome-wide Wiggler subtraction value
Genome_build: hg19/GRCh37
Supplementary_files_format_and_content: bigwig files were generated using the Wiggler tool; values represent Z-scores for each 10bp bin
