Ku Binds Telomeric DNA in Vitro - Titia de Lange Lab
... The DNA binding activity of Ku suggests that the protein may bind directly to telomeric DNA. However, because of the interaction of Hdf1p with Sir4p in yeast two-hybrid assays (39), it is also possible that in yeast, the interaction of Ku with the telomere is mediated by protein-protein interactions ...
