The mutant AP-1 proteins could aid in the discovery of a class of cellular genes that might be positively regulated by AP-1 mutants competent to bind methylated DNA. Components and MethodsHuman embryonic kidney 293 cells containing EBV bacmids and the HH51416 BL cell line were transfected with plasmids expressing wt or mutant ZEBRA, c-Fos, or c-Jun below control with the CMV immediate-early promoter. Activation with the EBV lytic cycle was assessed by Northern, Western, and Southern blotting and by indirect immunofluorescence. DNA-binding affinity was evaluated by EMSAs with radiolabeled duplex oligonucleotides that had been synthesized in an unmethylated or methylated state (SI Components and Approaches). ACKNOWLEDGMENTS.
