ADP-ribosylation regulates the activity of numerous proteins involved in the DNA damage response and repair. A new study shows that telomeric DNA can be ADP-ribosylated by PARP1, and prompt removal of the ADP-ribose by TARG1 is essential to preserve telomere integrity, unveiling DNA-ADP-ribosylation as a novel player in telomere stability.
