The development and application of cleavage under targets and tagmentation (CUT&Tag) technology.

Abstract

The regulation of chromatin structure and gene transcription in eukaryotic cells is an involved process mediated by histone modifications, chromatin-binding proteins, and transcription factors. Studying the distribution of histone modifications and transcription factors at the whole-genome level is crucial for understanding the mechanisms of gene transcription. Cleavage under targets and tagmentation (CUT&Tag) is a novel chromatin analysis method that has rapidly gained popularity in the field of epigenetics since its introduction. It has been widely used for the detection of chromatin modifications and transcription factors in different species. Furthermore, CUT&Tag has also been adapted to simultaneously detect multiple epigenetic modifications. Its integration with single-cell transcriptome, and spatial transcriptome analysis allows for a comprehensive examination of cell fate and functions. In this review, we aimed to provide an overview of the recent developments and applications of CUT&Tag and its derivatives, highlighting their significance in advancing our understanding of epigenetic regulation.
