Putative transcription factor-binding promoter motifs in down- and up-regulated differentially transcribed gene groups.

A: The AWTTW motif (logo inset) identified in the down-regulated gene group. B: The GRGGTM motif in the up-regulated group. The density of constituent motifs within 400 bp upstream of genes in the DTG group (unbroken line) and in artificially truncated 400 bp promoters (perforated line) is displayed together with a histogram of promoter lengths (grey bars). See Table 2 for motif constituents and statistics.
