The FLI portion of EWS/FLI contributes a transcriptional regulatory function that is distinct and separable from its DNA-binding function in Ewing sarcoma

M. A. Boone, C. Taslim, J. C. Crow, J. Selich-Anderson, I. A. Showpnil, B. D. Sunkel, M. Wang, B. Z. Stanton, E. R. Theisen, S. L. Lessnick

This study identifies the specific FLI regions in EWS/FLI critical for oncogenic transformation in Ewing sarcoma, showing the DNA-binding domain and a carboxyl-terminal alpha-helix are essential for transcriptional regulation and tumorigenesis.
