Title Efficient transcription-coupled chromatin accessibility mapping in situ
Organism Homo sapiens
Experiment type Genome binding/occupancy profiling by high throughput sequencing
Summary Chromatin accessibility mapping is a powerful approach to identify potential regulatory elements. In the popular ATAC-seq method, Tn5 transposase inserts sequencing adapters into accessible DNA (‘tagmentation’). CUT&Tag is a tagmentation-based epigenomic profiling method in which antibody tethering of Tn5 to a chromatin epitope of interest profiles specific chromatin features in small samples and single cells. Here we show that by simply modifying the tagmentation conditions for histone H3K4me2/3 CUT&Tag, antibody-tethered tagmentation of accessible DNA sites is redirected to produce accessible DNA maps that are indistinguishable from the best ATAC-seq maps. Thus, DNA accessibility maps can be produced in parallel with CUT&Tag maps of other epitopes with all steps from nuclei to amplified sequencing-ready libraries performed in single PCR tubes in the laboratory or on a home workbench. As H3K4 methylation is produced by transcription at promoters and enhancers, our method identifies transcription-coupled accessible regulatory sites.
Overall design We used Cleavage under targets and Tagmentation (Cut-and-Tag), a chromatin profiling strategy in which antibody-targeted controlled integration of DNA sequencing adapters produces libraries for paired-end DNA sequencing.
