Extraction protocol |
XL ChIP-seq: For ARID2, SS18, BRG1, TEAD4, FOSL2, CTCF, and MITF cells were cross-linked with 2 mM disuccinimidyl glutarate (DSG, Pierce 20593) in PBS for 45 min followed by 1% FA for 10 min at RT. For H3K27ac and H3K27me3 cells were cross-linked with 1% FA for 10 min at RT. ChIP was performed as previously described (Fontanals-Cirera B, Hasson D, Vardabasso C, Di Micco R et al. Harnessing BET Inhibitor Sensitivity Reveals AMIGO2 as a Melanoma Survival Gene. Mol Cell 2017 Nov 16;68(4):731-744.e9) ChIP-seq: Libraries for ChIP-seq were done as previously described (Fontanals-Cirera B, Hasson D, Vardabasso C, Di Micco R et al. Harnessing BET Inhibitor Sensitivity Reveals AMIGO2 as a Melanoma Survival Gene. Mol Cell 2017 Nov 16;68(4):731-744.e9) ATAC-seq: For all ATAC-seq libraries, 50k cells were harvested, tagmented with 2.5-5uL Nextera Tn5 Transposes from nextera for 30 min, amplified up to 10 cycles and purified essentially as previously described in ATAC protocols. Purified libraries were then size selected on 2% agarose gel (150-700bp).

Data processing |
XL ChIP-seq: Reads were aligned using Bowtie (version 0.12.7) with parameters -k 1 -m 1 --best -S -n 2 -l 65 -q. BAM files were generated using SAMtools. duplicated reads were removed using SAMtools. bigwig files were generated from BAM files using deepTools bamCoverage (version 2.4.1) with parameters –normalizeUsingRPKM –binsize 10. Significant peaks were called using MACS2 callpeak (version 2.1.1.2) with parameters -f BAM -g 2.7e9 -s 100 --bw 200 —slocal 1000 -q 0.01. ATAC-seq: Reads (40bp Paired-end) were aligned using Bowtie2 (version 2.1.0) with parameters -q -X 2000. BAM files were generated using SAMtools. Reads that align to mtDNA, with quality value Q<30, as well as duplicated reads, were discarded using in-house scripts and Samtools.. bigwig files were generated from BAM files using deepTools bamCoverage (version 2.4.1) with parameters –normalizeUsingRPKM –binsize 10. Significant peaks were called using MACS2 callpeak (version 2.1.1.2) with parameters –nomodel –nolambada –keepdup all –slocal 10000 Genome_build: GRCh37/hg19 Supplementary_files_format_and_content: fastq - raw illumina reads. bigwig - aligned reads pileup with deeptools
