A major issue in telomere research is to understand how the integrity of chromosome ends is controlled. Although several nucleoprotein complexes have been described at the telomeres of different organisms, it is still unclear how they confer a structural identity to chromosome ends in order to mask them from DNA repair and to ensure their...

Human telomeres are protected from DNA damage by a nucleoprotein complex that includes the repeat-binding factor TRF2. Here, we report that TRF2 regulates the 5′ exonuclease activity of its binding partner, Apollo, a member of the metallo-β-lactamase family that is required for telomere integrity during S phase. TRF2 and Apollo also suppress...
