Fusion oncoproteins acquire condensate propensity to initiate tumour formation

Gene fusions are potent drivers of cancer, and nuclear condensates are known to have a role in transcription. By creating synthetic fusion oncogenes, we show that nuclear condensate formation might be a general feature of fusion oncoprotein-directed transcription, including in brain tumour development.
