The replication of long tracts of telomeric repeats may require specific factors to avoid fork regression (Fouché, N., Ozgür, S., Roy, D., and Griffith, J. (2006) Nucleic Acids Res., in press). Here we show that TRF2 binds to model replication forks and four-way junctions in vitro in a structure-specific but sequence-independent manner. A synthetic peptide(More)
Among several different types of repetitive sequences found in the human genome, this study has examined the telomeric repeat, necessary for the protection of chromosome termini, and the disease-associated triplet repeat (CTG).(CAG)n. Evidence suggests that replication of both types of repeats is problematic and that a contributing factor is the repetitive(More)
Binding of the telomerase ribonucleoprotein from the ciliate Euplotes aediculatus to telomeric DNA in vitro has been examined by electron microscopy (EM). Visualization of the structures that formed revealed a globular protein complex that localized to the DNA end containing the E. aediculatus telomere consensus 3'-single-strand T(4)G(4)T(4)G(4)T(4)G(2)(More)
