Sp/Klf motifs are enriched at Klf9 peaks, they correlate with peak features, and they are required for transcriptional repression by Klf9. a Position weight matrices showing the Klf9 consensus motif (left) and the four most commonly occurring Sp/Klf motifs that were partially redundant with the consensus motif (right). b Histogram showing the probability of the Klf9 consensus motif occurrence (solid) and average enrichment (number of mapped reads; dashed) across all Klf9 peaks. c Number of non-redundant Sp/Klf motifs correlates with the mean tag density across a peak (R = .245, p = .0000002)
