CC -!- FUNCTION: 5'->3' double-stranded DNA exonuclease which may also possess
CC a cryptic 3'->5' double-stranded DNA exonuclease activity. Functions in
CC DNA mismatch repair. {ECO:0000256|RuleBase:RU910737}.
CC -!- COFACTOR:
CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC Evidence={ECO:0000256|RuleBase:RU910737};
CC Note=Binds 2 magnesium ions per subunit. They probably participate in
CC the reaction catalyzed by the enzyme. May bind an additional third
CC magnesium ion after substrate binding. {ECO:0000256|RuleBase:RU910737};
CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000256|ARBA:ARBA00004123,
CC ECO:0000256|RuleBase:RU910737}.
CC -!- SIMILARITY: Belongs to the XPG/RAD2 endonuclease family. EXO1
CC subfamily. {ECO:0000256|RuleBase:RU910737}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
CC {ECO:0000313|EMBL:EED43662.1}.
