mNE promoter. The sequence of the proximal mNE promoter, which is sufficient to direct myeloid gene expression, is depicted. Boxes enclose binding sites for CBF, C/EBP, c-Myb, and TBP.23 24 The core GGAA sequence of the ets binding site is underlined, and the wild-type mNE ets probe (-95/-71) used for EMSA is bracketed.
