Regulatory Sequence Analysis Tools


Regulatory Sequence Analysis Tools

Jacques van Helden. Nucleic Acids Res.


The web resource Regulatory Sequence Analysis Tools (RSAT) ( offers a collection of software tools dedicated to the prediction of regulatory sites in non-coding DNA sequences. These tools include sequence retrieval, pattern discovery, pattern matching, genome-scale pattern matching, feature-map drawing, random sequence generation and other utilities. Alternative formats are supported for the representation of regulatory motifs (strings or position-specific scoring matrices) and several algorithms are proposed for pattern discovery. RSAT currently holds >100 fully sequenced genomes and these data are regularly updated from GenBank.

Feature map of the patterns discovered in Table 2. Each box corresponds to one hexanucleotide. Transcription factor binding sites are generally revealed as combinations of boxes, which reflect the fact that the consensus is >6 nt. The blue box corresponds to CACGTG, the core of Met4p binding site. Some examples of the smaller boxes, corresponding to putative Met31p binding sites, are indicated. Notice that putative Met31p binding sites are often associated to putative Met4p binding sites, suggesting an interaction between the two factors.
