Web interface of the differential binding site search. Gene IDs from control gene set (unchanged in DNA microarray data) and regulated gene set (upregulated or downregulated from microarray data) are pasted into respective windows. The threshold of binding site ratio is defined by the user. The user can specify a range of interest with three choices of regions (upstream from the transcription start site, upstream from the start codon, or downstream from the stop codon). TF, transcription factor.
