== Function ==
 +
[https://www.uniprot.org/uniprot/KU_MYCTU KU_MYCTU] With LigD forms a non-homologous end joining (NHEJ) repair enzyme. Binds linear dsDNA with 5'- and 3'-overhangs but not closed circular dsDNA nor ssDNA. One dimer binds for every 30 bp. Recruits and stimulates the ligase activity of LigD but not of T4 ligase or a human ligase complex (LIG4/XRCC4). Attenuates the 3'- to 5'-exonuclease activity of LigD. Stimulates the template-directed addition of dNTPs by LigD on 5'-overhangs and nuclease activity on 3'-overhangs.<ref>PMID:12215643</ref> <ref>PMID:15499016</ref> <ref>PMID:15778718</ref> <ref>PMID:16023671</ref>
