The EWSR1::FLI1 fusion protein is the oncogenic driver of Ewing sarcoma (EwS). Here, the authors find that EWSR1::FLI1 plays a non-canonical role in mRNA decay via interactions with the CCR4-NOT deadenylation complex and the RNA-binding protein HuR. This role uncovers a new therapeutic vulnerability of EwS to HuR inhibition.
