EWSR1/FLI1 Fusion Protein Type 1

**Semantic type:** Amino Acid, Peptide, or Protein

**Definition:** A fusion protein (504 aa, ~55 kDa) encoded by the EWSR1/FLI1 fusion gene type 1. This protein is comprised of the transactivation domain of the RNA-binding protein EWS fused to the C-terminal domain of the Friend leukemia integration 1 transcription factor protein, which includes the ETS DNA binding domain.
