Chromatin Transposase Accessibility Sequencing is a new high-throughput sequencing technique developed by Professor William Greenleaf in 2013 which uses DNA transposase to probe chromatin accessibility with Tn5 transposase. This technique, which is simpler and more sensitive than DNase-seq, MNase-seq and FAIRE-seq and requires fewer cells, has been used to study chromatin accessibility using Tn5 transposase. ATAC-seq is important for the study of epigenetic molecular mechanisms because it can map chromatin accessibility on a genome-wide scale, compare open chromatin regions in different tumour samples, compare differences in transcription factor binding between treatments, reveal nucleosome localisation information and transcription factor binding sites, and can be used to locate specific unknown transcription factors, which can be used in combination with other methods to screen for specific transcription factors of interest. It is possible to combine this approach with others to investigate specific regulatory factors. Herein, ATAC-seq is systemically profiled to present that ATAC-seq has enormous potential to drive future discoveries in the field of genomics and beyond.
