(A) EMSAs showing a lack of DNA binding to oligos in which DLX cis elements have been mutated. Asterisks denote bound DNA complexes of control oligos. Unlabeled competitors are denoted WT (wild-type) and mut (mutant). (B) Luc assays mutation of the DLX or GATA binding sites either has no effect on DLX-mediated repression diminishes (DLX 5′) or eliminates (DLX 3′) Bmp responsiveness (DLX/GATA 5′, GATA 3′). Dotted lines denote where gel lanes were rearranged.
