Fig. 2. — Inhibitory effects of the 25 most active arylstibonic acids on DNA binding of three B-ZIP (CREB, C/EBPα, and VBP) and two B-HLH-ZIP (Mitf and USF) proteins. EMSA showing the protein/DNA bands at five arylstibonic acid concentrations: 0.1 (A), 0.3 (B), 1 (C), 3 (D), and 10 (E) μM. Each sample included 10 nM protein dimer and 7 pM ³²P-labeled 28-base pair DNA probe containing the consensus binding site of each protein, with the exception of the “DNA only” lane. The protein/DNA complexes were resolved on 7.5% native gels.
