Sp1 and MAZ competition for the same binding site within the 34-nt oligonucleotide in vitro. (A) Autoradiograms from EMSA using a constant amount of Sp1 protein and increasing quantities of GST-MAZ protein. (B) Autoradiograms from EMSA using a constant amount of GST-MAZ protein and increasing quantities of Sp1 protein. The lower panels show quantitation of the bands in each fraction.
