WebCBX2–PRC1 subunits depends on CBX2, suggesting a mech-anism underlying the assembly of CBX2–PRC1 condensates. In summary, our results reveal that PcG condensates assem-ble through liquid–liquid phase separation (LLPS) and sug-gest that phase-separated condensates can organize PcG-bound chromatin. WebCBX6 occupies a small fraction of Polycomb targets. At this stage, we cannot exclude the possibility of some clients having weak phase separation capacities.
