Off-the-shelf proximity labeling
In this study we developed a new assay to perform proximity biotinylation in cells without the requirement for genetic manipulation or transfection to fuse a biotin ligase to a protein of interest. We show the specificity by targeting H3K9me3 and performing ChIP-seq for the biotin modification. Targeting IgG was used as a control. By doing so, we identified flywch1 as a new protein binding to H3K9me3 regions, which we validated using ChIP-seq (IgG ChIP was used as a control) Overall design: ChIP-seq profiling of biotin after H3K9me3 or IgG targeting and ChIP-seq for Flywch1 or IgG
