CC -!- FUNCTION: DNA polymerase that functions in several pathways of DNA
CC repair. Involved in base excision repair (BER) responsible for repair
CC of lesions that give rise to abasic (AP) sites in DNA. Also contributes
CC to DNA double-strand break repair by non-homologous end joining and
CC homologous recombination. Has both template-dependent and template-
CC independent (terminal transferase) DNA polymerase activities. Has also
CC a 5'-deoxyribose-5-phosphate lyase (dRP lyase) activity.
CC {ECO:0000256|RuleBase:RU366014}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=a 2'-deoxyribonucleoside 5'-triphosphate + DNA(n) =
CC diphosphate + DNA(n+1); Xref=Rhea:RHEA:22508, Rhea:RHEA-COMP:17339,
CC Rhea:RHEA-COMP:17340, ChEBI:CHEBI:33019, ChEBI:CHEBI:61560,
CC ChEBI:CHEBI:173112; EC=2.7.7.7;
CC Evidence={ECO:0000256|ARBA:ARBA00024632,
CC ECO:0000256|RuleBase:RU366014};
CC -!- COFACTOR:
CC Name=Mn(2+); Xref=ChEBI:CHEBI:29035;
CC Evidence={ECO:0000256|ARBA:ARBA00001936};
CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000256|RuleBase:RU366014}.
CC -!- SIMILARITY: Belongs to the DNA polymerase type-X family.
CC {ECO:0000256|ARBA:ARBA00008323, ECO:0000256|RuleBase:RU366014}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
