Distribution of putative promoter motifs relative to transcription start sites. (A) Distributions of consensus motifs CACGTG, CCTNAGG and ACCGCC within promoter regions of ‘tight’ transcription start sites. The distribution of putative TATA box motifs (TATAA) are also shown. Each point represents the frequency density of motifs starting within a 10 bp window, the midpoint of which is plotted. Both CACGTG and ACCGCC peak at approximately -70 bp and the TATA box at -45 bp from the TSS, while the position of the CCTNAGG motif is less sharply defined across a region from approximately -70 bp to -120 bp. (B) Sequence logos of promoter motifs and surrounding nucleotides (from promoter regions associated with ‘tight’ TSS).
