Plasmids can be amazing and simple tools for studying gene regulation. They are used to study how transcription factors and other trans-regulatory elements (TREs) and some cis-regulatory elements (CREs), like promoters, influence gene expression. However, scientists frequently return to native chromosomes because chromatin context matters. The impact of TREs and CREs on gene expression is commonly investigated via Chromatin Immunoprecipitation (ChIP) and chromatin capture techniques, respectively, but these two separate methods are not without their own technical challenges. Enter the Xu Lab's CAPTURE, a method for identifying TREs and CREs that partners CRISPR’s targeting abilities with the strength of the biotin-streptavidin interaction. CAPTURE is capable of identifying old and new TREs and CREs, CRE-CRE interactions, and has even provided enough data for Liu et al to re-draw the beta-globin locus regulation model.
