H3K4me1 ChIP-seq of untreated HeLa S3 cells

We used ATLAS-seq to map the sites of integration of an engineered LINE-1 (L1) retrotransposon into the genome of HeLa S3 cells. Then, we compared the position of these sites with publicly available genomic datasets. In order to cross-corroborate our findings with datasets obtained in the same cell stock as used in our retrotransposition assays, we also performed H3K4me1 ChIP-seq.
