From: Genome-wide analysis of core promoter elements from conserved human and mouse orthologous pairs
Average sequence similarity between orthologous human and mouse promoter regions is very high at the transcription start site (vertical dotted line), and drops sharply both up- and downstream of this point. Points indicate the mean percent identity in sliding 20-base windows along our dataset of 9,010 orthologous mouse-human promoter pairs. 95% confidence interval bars are plotted at every 10 bases.
