From: Promoter-like epigenetic signatures in exons displaying cell type-specific splicing
K-means clustering based on epigenetic signatures of regulated exons. a, b boxplots represent differential ChIPSeq signal for more included (a) and less included (b) exons. Each square represents one group of exons identified by K-means clustering. The number of exons present in each cluster is indicated to the left of each cluster. Three clusters of exons show strong differential signal for H3K9ac, H3K27ac, and H3K4me3 in the direction of the inclusion level change. These exons were called ‘promoter-like’ exons due to the nature of these histone modifications
