E2F recognition sites are required for activation of the NPAT promoter by E2F proteins. (A) Nucleotide sequences of E2F recognition sites in wild-type (WT) and mutant (Mut) NPAT promoters. The mutated nucleotides are shown in bold type. (B) Responses of wild-type and mutant NPAT promoters to activation by different E2F proteins. U2OS cells were transfected with the vector or the indicated E2F-expressing plasmid together with the indicated luciferase reporter constructs. The samples were analyzed as described in the legend to Fig. 2B.
