Cut&tag: a powerful epigenetic tool for chromatin profiling

Area of Science:

• Epigenetics and Molecular Biology
• Genomics and Bioinformatics

Background:

• Genome-wide analysis of transcription factors and chromatin modifications is crucial for understanding gene regulation, cell differentiation, and cellular responses.
• Chromatin immunoprecipitation is a standard method for chromatin mapping, with newer enzyme-tethering techniques emerging for live cells.

Purpose of the Study:

• To review the applications of Cleavage Under Targets and Tagmentation (CUT&Tag) and its derivatives.
• To provide a detailed explanation of the advantages and disadvantages of CUT&Tag.
• To discuss the future development trends and applications of CUT&Tag in epigenetics.

Main Methods:

• Cleavage Under Targets and Tagmentation (CUT&Tag) is a novel chromatin profiling technique rapidly adopted since 2019.
• CUT&Tag has been adapted across species to map chromatin modifications and transcription factors (TFs).
• Scalable single-cell CUT&Tag enables distinguishing cellular identity, epigenetic features, and spatial chromatin profiling.

Main Results:

• CUT&Tag effectively maps chromatin modifications and TFs, revealing associations with physiological and pathological processes.
• The technique supports joint profiling of the epigenome, transcriptome, or proteome from the same sample.
• CUT&Tag offers versatility across different biological platforms and species.

Conclusions:

• CUT&Tag is a versatile and powerful epigenetics tool for genome-wide chromatin profiling.
• Its adaptability to single-cell analysis and multi-omic profiling highlights its potential in diverse research areas.
• Continued development promises expanded applications in understanding complex biological processes.
