Purpose : Fusion genes(EWS-Fli-1 and EWS-erg ) function as transcription activators and are essential for maintaining tumorigenic properties in Ewing`s sarcoma cells. Several reports have noted that Ets family transcription factors bind with CBP(CREB binding protein) in vitro. To understand the interaction of fusion proteins and CBP, we studied the CBP protein in TC135 cells expressing the EWS-Fli-1 gene. We... |
