EWSR1/ATF1 Fusion Protein Type 1

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

**Definition:** A fusion protein (537 aa, ~57 kDa) encoded by the EWSR1/ATF1 type 1 fusion gene. This protein is comprised of the transactivation domain of the RNA-binding protein EWS followed by the DNA-binding basic domain and leucine zipper dimerization domain of the cyclic AMP-dependent transcription factor ATF-1 protein.

**Synonyms:** - EWS-ATF1 Fusion Protein Type 1 - EWS/ATF1 Oncoprotein Type 1 - EWSR1-ATF1 Fusion Protein Type 1 - EWSR1::ATF1 Fusion Protein Type 1
