== Function ==
[https://www.uniprot.org/uniprot/LIGD_PSEAE LIGD_PSEAE] With Ku probably forms a non-homologous end joining (NHEJ) repair enzyme, which repairs dsDNA breaks (DSB) with reduced fidelity. Acts as a DNA ligase on singly nicked dsDNA, fills dsDNA gaps (3- or 4- nucleotide gaps, prefers a 5'-phosphate at the gap distal end, prefers dNTPs over rNTPs) (PubMed:20018881), has DNA-directed DNA polymerase activity (templated primer extension) and DNA-directed RNA polymerase activity (PubMed:15897197), adds 1 or 2 non-templated rNTP (or less well dNTP) to ssDNA or blunt-end dsDNA (primer extension). Has 3' resection activity, removing 3'-rNMPs from DNA using its 3'-ribonuclease and 3'-phosphatase activities sequentially. Resection requires a 2'-OH in the penultimate nucleoside position (i.e. a ribo- not deoxyribonucleoside) (PubMed:15897197), although the 3'-phosphatase activity does not, and its specific activity is 16-fold higher on a DNA substrate (PubMed:16046407). On appropriate substrates will extend a DNA primer to the end of the template strand and then incorporate a non-templated nucleotide.<ref>PMID:15897197</ref> <ref>PMID:16046407</ref> <ref>PMID:20018881</ref>  The preference of the polymerase domain for rNTPs over dNTPs may be advantageous in quiescent cells where the dNTP pool may be limiting.
