    Abstract

    BACKGROUND:

    DNA duplex sequences that can be targets for triplex formation are highly over-represented in the human genome, especially in regulatory regions.

    RESULTS:

    Here we studied using bioinformatics tools several properties of triplex target sequences in an attempt to determine those that make these sequences so special in the genome.

    CONCLUSION:

    Our results strongly suggest that the unique physical properties of these sequences make them particularly suitable as "separators" between protein-recognition sites in the promoter region.
