Triple-helix formation interferes with the transcription and hinged DNA structure of the interferon-inducible 6-16 gene promoter.


The interferon responsive element (IRE) of the 6-16 gene lies within two 39-bp elements in tandem. A purine-rich oligodeoxynucleotide, oligo(dN), was found to be able to pair with the purine-rich strand of the IRE in an antiparallel orientation which led to triple-helix formation with Mg2+ being necessary for triplex stability.
