Figure 4From: A quantitative atlas of histone modification signatures from human cancer cellsProteomic analysis of histone H4 PTMs across cell lines. Hierarchical clustering of the 24 lines was performed based on abundances of histone H4 PTMs (shown in right vertical axis). Data are shown as log2 enrichment of histone PTM levels for a given line based on average PTM levels across all 24 lines.Back to article page
