Abstract

Regulation of gene expression is primarily controlled by changes in the proteins that occupy genes' regulatory elements. We developed genomic locus proteomics (GLoPro), in which we combine CRISPR-based genome targeting, proximity labeling, and quantitative proteomics to discover proteins associated with a specific genomic locus in native cellular contexts.
