[https://www.uniprot.org/uniprot/APLF_HUMAN APLF_HUMAN] Nuclease involved in single-strand and double-strand DNA break repair. Recruited to sites of DNA damage through interaction with poly(ADP-ribose), a polymeric post-translational modification synthesized transiently at sites of chromosomal damage to accelerate DNA strand break repair reactions. Displays apurinic-apyrimidinic (AP) endonuclease and 3'-5' exonuclease activities in vitro. Also able to introduce nicks at hydroxyuracil and other types of pyrimidine base damage.<ref>PMID:17396150</ref> <ref>PMID:17353262</ref>

== Publication Abstract from PubMed ==
Addition of poly(ADP-ribose) (PAR) is an important post-translational modification in higher eukaryotes. Several DNA repair and checkpoint proteins possess specific PAR-binding zinc-finger (PBZ) modules critical for function. Here, we present solution structures of the two PBZ modules of aprataxin and PNK-like factor (APLF), revealing a novel type of zinc finger. By combining in vivo PAR-binding data with NMR interaction data using PAR fragments, we propose a structural basis for PBZ-PAR recognition.
Solution structures of the two PBZ domains from human APLF and their interaction with poly(ADP-ribose).,Eustermann S, Brockmann C, Mehrotra PV, Yang JC, Loakes D, West SC, Ahel I, Neuhaus D Nat Struct Mol Biol. 2010 Feb;17(2):241-3. Epub 2010 Jan 24. PMID:20098424<ref>PMID:20098424</ref>
