From: Core promoter structure and genomic context reflect histone 3 lysine 9 acetylation patterns
Four simplified instances of typical acetylation patterns. Cartoon representation of typical situations around single peak and broad promoters. In the upstream cluster of H3K9 acetylation, around ~40% of the promoters have a single peak architecture (A) while ~60% have a broad architecture (B). In the centered (C) and downstream (D) cluster, the broad architecture is even more prevalent with ~80% of all cases.
