Here, we developed a new sensitive method, NPC-DamID, which combines in vitro reconstitution of nuclear import and DamID technology. The fixation-free method identifies chromatin interactions at the NPCs in intact nuclei from cells and tissues. We found that NPCs are preferentially associated with common and hierarchically arranged super-enhancers (SEs) across multiple cell types. We also uncovered phase-separated condensates at NPCs that compartmentalize and concentrate transcriptional coactivators and structural proteins at SE-regulated genes. Our results support NPCs as anchoring sites for SE regulatory hubs and cell-type-specific transcriptional control.","lang":"eng"}],"month":"06","doi":"10.7554/elife.87462","oa":1,"title":"High-precision mapping of nuclear pore-chromatin interactions reveals new principles of genome organization at the nuclear envelope","date_updated":"2024-07-31T11:56:25Z","year":"2023","oa_version":"Submitted Version","acknowledgement":"This work was supported by M.H.’s NIH R01 grants (NS096786, GM126829) and Salk Cancer Center Support Grant P30 CA014195.
