Histone code

Histone code

H3K4me3 is enriched in transcriptionally active promoters.[12]

H3K9me3 is found in constitutively repressed genes.

H3K27me3 is found in facultatively repressed genes.[7]

H3K36me3 is found in actively transcribed gene bodies.

H3K9ac is found in actively transcribed promoters.

H3K14ac is found in actively transcribed promoters.

H3K27ac distinguishes active enhancers from poised enhancers.

H3K122ac is enriched in poised promoters and also found in a different type of putative enhancer that lacks H3K27ac.
