TF motifs within TEs reside within an open chromatin environment. a) Pie charts displaying the proportions of accessible chromatin sites containing the indicated TF-binding motifs that reside within (black) or outside of (gray) annotated TEs. Accessible sites were identified using ATAC-seq data from a previous publication (Daugherty et al. 2017). TF-binding motif identifiers from the Cis-BP database (Weirauch et al. 2014) are shown in parentheses. Only TF motifs with greater than 10% of accessible motifs within TEs are displayed. b) List of the top 5 TEs that have the greatest numbers of each indicated TF motif within accessible chromatin sites. c) Number of protein-coding genes that have TEs containing accessible TF motifs from panel (a) residing within their promoter regions. The total number of genes with accessible TE-provided TF motifs in their promoters is 1,293.
