| Extraction protocol |
Capture-C probes at CCNE1 promoter regions was designed using CapSequm. Approximately 1 × 107 cells were crosslinked by 2% formaldehyde, followed by lysis, homogenization, DpnII digestion, ligation and de-crosslinking. DNA was sonicated using a Covaris to 150–200 bp to produce DNA suitable for oligo capture. Three micrograms of sheared DNA was used for sequencing library preparation (New England Biolabs). The promoter sequence of CCNE1 was double captured by sequential hybridization to customized biotinylated oligos (IDT, Supplementary Table 14) and enrichment with Dynabeads (LifeTech). Captured DNA was sequenced on the Illumina HiSeq 3000 instrument with the 2x150 bp configuration.

| Description |
Capture-C in YCC11
|
| Data processing |
Library strategy: Capture-C
Pre-processing of raw reads was performed to remove adaptor sequences (trim_galore, http://www.bioinformatics.babraham.ac.uk/projects/trim_galore/) and overlapping reads were merged using FLASH. In order to achieve short read mapping to the hg19 reference genome, the resulting pre-processed reads were then in-silico digested with DpnII and aligned using Bowtie (using p1, m2, best and strata settings). Aligned reads were processed using Capture-C analyser to (i) remove PCR duplicates, and (ii) classify sub fragments as ‘capture’ if they were contained within the capture fragment; ‘proximity exclusion’ if they were within 1 Kb on either side of the capture fragment; or ‘reporter’ if they were outside of the ‘capture’ and ‘proximity exclusion’ regions. We additionally used the r3Cseq package on the capture and reporter fragments to identify significant interactions of the viewpoint against a scaled background (q-value <0.05, FDR).
