| Extraction protocol |
For each batch of ChIP experiments ~12 million cells were crosslinked in 2% PFA for 45 min at 4°C. From this point onward, cells were processed via the ChIP-IT High Sensitivity kit (Active motif) as per manufacturer’s instructions, but using the NEXSON protocol for the isolation of nuclei [1]. Chromatin was sheared to 200-500 bp fragments on a Bioruptor Plus (Diagenode; 2x 20-26 cycles of 30s “on” and 30s “off”, at the highest power setting), and immunoprecipitations were carried out by adding 4 μg of the appropriate antiserum (CHD6, A301-221A Bethyl; TF3B, A303-673A Bethyl) to ~30 μg of chromatin and incubating on a rotator overnight at 4°C in the presence of protease inhibitors. Following addition of protein A/G agarose beads and washing, DNA was purified using the ChIP DNA Clean & Concentrator kit (Zymo Research) and used in qPCR or sequencing on a HiSeq4000 platform (Illumina).

| Data processing |
ChIP-seq reads were aligned to the hg19 using BWA, reads with mapping quality below 10 were filtered out, duplicates were removed using Picard.
peaks were called using MACS2 peak caller with the following arguments: -f BAM -g hs -s 100 --keep-dup 1 -q 0.01 (for CHD6)
Genome_build: hg19
Supplementary_files_format_and_content: The Wig file is generated from the bedGraph file, using an in-house script that computes the extended read coverage at a user-defined step size (default: 20 bp). The extended read coverage is normalized to a library size of one million mapped reads, and converted into the TDF format using the toTDF command from the igvtools package (http://www.broadinstitute.org/software/igv/igvtools).
