Supplementary Figure 5: Expression of 80 bp native promoter fragments.
From: Deciphering eukaryotic gene-regulatory logic with 100 million random promoters
Distributions of measured expression levels (x axis) for 80 bp fragments of native yeast promoters, corresponding to different regions of the promoter (colors). Although each region included sequences from all promoters, the regions upstream of -200 are covered by nucleosomes in many promoters, which may explain their tendency to express at lower levels.
