Poly-ADP-ribosylation is a unique post-translational modification that controls various nuclear events such as repair of DNA single-strand breaks. Recently, the protein containing the poly-ADP-ribose (pADPr)-binding zinc-finger (PBZ) domain was shown to be a novel AP endonuclease and involved in a cell cycle checkpoint. Here, we determined the three-dimensional structure of the PBZ domain from Drosophila melanogaster CG1218-PA using NMR spectroscopy. The domain folds into a C2H2-type zinc… CONTINUE READING
