an oncogenic RNA-binding protein. Might normally function as a repressor. Binds RPB3, SF1, calmodulin and RNA. Interacts with and regulated by Pyk2. Relocates from cytoplasm to ribosomes upon Pyk2 activation. EWS-fusion-proteins (EFPS) may play a role in the tumorigenic process. They may disturb gene expression by mimicking, or interfering with the normal function of CTD-POLII within the transcription initiation complex. 5 alternatively-spliced isoforms have been described.

Protein type: Oncoprotein; RNA-binding; Transcription, coactivator/corepressor
