Sequence-specific DNA recognition by the Myb-like domain of the human telomere binding protein TRF1: A model for the protein-DNA complex

Abstract excerpt

Telomeres consist of tandem arrays of short G-rich sequence motifs packaged by specific DNA binding proteins. In humans the double-stranded telomeric TTAGGG repeats are specifically bound by TRF1 and TRF2. Although telomere binding proteins from evolutionarily distant species are not sequence homologues, they share a Myb-like DNA binding motif. Here we have used gel retardation, primer extension and DNase I...
