Poly(ADP-ribosyl)ation represents an important post-translational modification in higher eukaryotes. Several DNA repair/checkpoint proteins possess specific PAR-Binding Zinc finger (PBZ) modules critical for function. Here, we present solution structures of the two PBZ modules of APLF (Aprataxin and PNK-like factor), revealing a novel type of zinc finger. By combining in vivo PAR-binding data with NMR interaction data using PAR fragments, we suggest a structural basis for PBZ-PAR recognition.
