Transcription factor binding sites contained in a gene set. Tabular account of known transcription factor binding sites of any length found within the putative promoter regions of the prophenoloxidase case study gene set. Each factor is indicated (factor name), along with the number of genes in which it is found (#genes), its frequency (%set) within the current gene set as compared to its frequency (%prom) within all promoter regions in the An. gambiae genome, and the difference between the latter two (fold+/-). The transcript identifiers containing each transcription factor binding site are indicated last (genes). Fifteen of the 287 binding sites found in the case study comparison are shown in this abbreviated figure.
