We have cloned the gene for a new ets-related transcription factor , ERP ( ets-related protein ), from the murine pre-B cell line BASC 6C2 and from mouse lung tissue .
 ( cell line: murine pre-B cell line, None) , ( protein: transcription factor, None) , ( protein: ets-related protein, None) , ( protein: ERP, None) , ( cell line: BASC 6C2, None) , ( protein: ets-related transcription factor, None)
