Figure 1.

Classification of structural CEs variants with respect to and conservation of anchor and partner motifs (A), their mutual orientation (B), overlap or spacer (C). Cyan, green and light green colors on the panel B distinguish CEs with a spacer, partial and full overlaps, respectively. The color range from red to pink on the panel A denotes the conservation level of a motif; brown/orange and grey colors mark imbalance in CEs with more conserved anchor/partner motifs and a balance between conservation of motifs.
