From: Evolution of motif variants and positional bias of the cyclic-AMP response element
Variation of representation index (RI) of CRE motifs over human TSS-SR regions. The representation index of each 50 bp window along the human TSS-SRs are plotted for the 5 CRE motifs showing the strongest positional bias in the 3 windows from -1 to -150 bp away from the TSS.
