Gel mobility shift assay and competition experiment determine the specificity of DNA–protein complexes formed with dynCRE3 (A) and dynAP-1 (B). Unlabeled consensus AP-1, CRE, and the unrelated AP-4 sequences were used to compete for proteins bound to radiolabeled dynCRE3 (A) and dynAP1 (B) promoter elements. Striatal samples were pooled from several l-DOPA-treated rats. The experiment was repeated three times.
