De novo motif enrichment

Shown are the nine top motifs from de novo analysis of 500-nt sequences from 4195 of NF-κB/RelA ChIP-Seq peaks (representing the highest 20% significance scores). Column 1, the Weblogo for the 11 nt de novo motif search; 2, motif name; 3, motif rank according to MEME; 4, the corrected empirical P-value computed by us (green indicates enrichment, red indicates depletion); 5 and 6, percentage and number of motif occurrences within Alu repeats; 7 Alu repeat enrichment; 8, P-value for Alu enrichment (green) or depletion (red); 9 and 10, enrichment of DNase hypersensitive sites (Genome Browser OpenChromSynth_K562_DNase track) and its P-value; 11 and 12, enrichment of CpG islands (Genome Browser CpG Islands track) and its P-value.
