Abstract: A novel poly(ADP-ribose)-binding zinc finger (PBZ) motif is identified. This motif is found in several eukaryotic checkpoint and DNA repair proteins, such as CHFR and APLF. Mutations in the PBZ of CHFR affect its function in checkpoint regulation, suggesting that both the poly (ADP-ribosyl)ation of proteins, and the interaction of this modification with other factors, is important for the DNA damage response.
