Figure 1. Reporter gene analysis of histone H3 promoter deletion series in the HEK-293 cell line.

Figure 1

The reporter gene activity of the indicated constructs is shown as a statistical result (relative to the longest construct, which is set to the value of 1.0; error bars, S.E.M.; c, control construct pGL3-basic) of five independent experiments. A diagram of the promoters with the lengths of the constructs indicated is shown below each graph. Arrow, transcription start site; numbers, distance to transcription start site in bp; luc+, firefly luciferase coding sequence; black boxes, TATA boxes; white boxes, CCAAT boxes; grey boxes, ATF boxes; fusion site, ATG start codon.
