To determine the functionality of both the C/EBP- and GATA- binding sites , we analyzed whether C/EBPbeta and GATA-1 can stimulate the MBP promoter in the C/EBPbeta and GATA-1 negative Jurkat T-cell line .
 ( protein: GATA-1, None) , ( cell line: C/EBPbeta and GATA-1 negative Jurkat T-cell line, None) , ( protein: GATA-1, None) , ( protein: MBP, None) , ( cell line: Jurkat T-cell line, None) , ( protein: C/EBPbeta, None) , ( DNA: MBP promoter, None) , ( protein: C/EBPbeta, None)
