Transcription Factor Binding Site Positioning in Yeast: Proximal Promoter Motifs Characterize TATA-Less Promoters
Figure 5
Estimated average affinity profiles for the initiator motif.
The horizontal axis shows position relative to TSS and the vertical axis shows the average WM score at the corresponding position, averaged over all TATA (red) and TATA-less (green) promoters. The inset shows the initiator motif. The upstream maximum in TATA promoters corresponds to the preferred position of the TATA motif, and the upstream maximum in the TATA-less promoters corresponds to the preferred position of alternative PPMs in TATA-less promoters.
