"WebFli-1 aberrant expression is also associated with chromosomal abnormalities in humans. In pediatric Ewing’s sarcoma a chromosomal translocation generates a fusion of the 5’ transactivation domain of EWSR1 (also known as EWS) with the 3’ Ets domain of Fli-1. The resulting fusion oncoprotein, EWS/Fli-1, acts as an aberrant transcriptional activator. " - Ews fli1
