Genome-wide maps of histone modification in mast cells
Epigenomic studies demonstrate that monomethylation of lysine residue 4 on histone 3 (H3K4me1) marks genes that are poised to be transcribed, whereas acetylation of lysine residue 27 on histone 3 (H3K27ac) identifies genes that are actively being transcribed. The combined presence of H3K4me1 and H3K27ac modifications predicts enhancer activity. To detect these marks genome-wide, we performed H3K4me1 and H3K27ac ChIP-seq analysis of mast cells to identify the putative mast cell enhancers. Overall design: H3K4me1 and H3K27ac ChIP-seq to identify the putative enhancers in mast cells.
