While much attention has been focused on chromatin at promoters and exons, human genes are mostly composed of intronic sequences. Analyzing published surveys of nucleosomes and 41 chromatin marks in humans, we identified histone modifications specifically associated with 5′ intronic sequences, distinguishable from promoter marks and bulk nucleosomes. These intronic marks were spatially reciprocal to H3K36me3, typically transitioning near internal exons. Several marks transitioned near bona fide exons, but not near nucleosomes at exon-like sequences. Thus, we interrogated splicing for a role in histone marking. Despite dramatic changes in regulated alternative splicing, histone marks were stable. Notably, these findings are consistent with a role for exon definition in influencing histone marks. In summary, we demonstrate that the location of many intragenic marks in humans can be distilled into a simple organizing principle: association with 5′ intronic or 3′ exonic regions.
