Wide range of motif spacings for TF dimers predicted in K562 cells. Predicted dimers that varied only in their spacing (same motif pair and orientation) were grouped together and ranked by the p-value of the most significant spacing. For each such group of dimer predictions in K562 ChIP-seq peaks, we show the motif complex enrichment p-value as a function of motif spacing. Spacings to the left of the red line correspond to overlapping motifs.
