Assays for Transposase-Accessible Chromatin using sequencing, short for ATAC-Seq, is a next-generation sequencing (NGS)-based method to study the open regions of chromatin on a genome-wide scale. ATAC-Seq has the advantages of easy operation, no crosslinking required, high signal-to-noise ratio, and low requirement for sample amount. Combined the data of ATAC-Seq, RNA-Seq, and epigenomics, the relationship between gene differential expression and regulation can be studied more accurately and comprehensively.
The DNA of eukaryotes is tightly bound to a group of proteins called histones, which constitute half the mass of a eukaryotic chromosome. There are numerous units that DNA enwinds histone formed a bead like structure called nucleosome, and the chromatin looks like many beads on a string. DNA replication and gene transcription require the unwinding of the higher structure of DNA. Open chromatin regions are these folded regions that contain important binding sites for transcription factors and transcriptional regulatory elements. ATAC-Seq utilizes the hyperactive mutant Tn5 transposase to insert sequencing adapters into accessible DNA regions, through which the open chromatin sequence can be separated from the entire chromatin, followed by next-generation sequencing and corresponding bioinformatics analysis. The research on open chromatin addresses the needs for deeper understanding of gene regulation, transcription factors that relate to cell physiology and diseases, etc.
