Abstract To comprehensively characterize the functions of a transcription factor (TF), it is required to analyze the interaction of this TF with its targeted loci. Several methods such as β-glucuronidase (GUS) or luciferase reporter, yeast one-hybrid (Y1H), chromatin-immunoprecipitation (ChIP), and electrophoretic mobility shift assay (EMSA) assays have been developed. Of these, EMSA is an in vitro method which can prove the direct interaction between TF and targeted DNA fragment. This protocol is to provide a detailed procedure for a safe EMSA assay (without using any radioisotope).

We have analysed the transcriptional regulation of the human histone H3 genes using promoter deletion series, scanning mutagenesis, specific mutagenesis and electrophoretic mobility-shift assay experiments. The promoters of five of the six examined histone H3 genes showed near-maximal activity at lengths of 133–227 bp: H3/d 198 bp, H3/h 147 bp, H3/k 133 bp, H3/m 227 bp, H3/n 140 bp (exception H3/i). To search for functional cis-elements within these regions, we performed scanning mutagenesis of the two histone H3 promoters H3/k and H3/m. Mutagenesis revealed that the functional framework of the histone H3 promoters consists of a TATA box and two tandemly arranged CCAAT boxes in relatively fixed positions. Alterations of the distance between the CCAAT boxes and of the distance between the CCAAT boxes and the TATA box resulted in significant loss of activity. In electrophoretic mobility-shift assay experiments, the factor CBF (CCAAT-binding factor)/NF-Y (nuclear factor-Y) bound to isolated CCAAT boxes of the H3/k promoter. This suggests that an initiation complex is formed on the histone H3 promoter that has a defined structure and limited flexibility, consisting of two molecules of CBF/NF-Y and further (general or specific) transcription factors.
