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 (MMR) to excise mismatch-containing DNA tracts
CC directed by strand breaks located either 5' or 3' to the mismatch. Also
CC exhibits endonuclease activity against 5'-overhanging flap structures
CC similar to those generated by displacement synthesis when DNA
CC polymerase encounters the 5'-end of a downstream Okazaki fragment.
CC Required for somatic hypermutation (SHM) and class switch recombination
CC (CSR) of immunoglobulin genes. Essential for male and female meiosis.

CC -!- COFACTOR:
CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420; Evidence={ECO:0000250};
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:0000250};
CC -!- SUBUNIT: Interacts with the MLH1-PMS2 heterodimer via MLH1. Interacts
CC with MSH3. Interacts with the MSH2-MSH6 heterodimer via MSH2, and this
CC interaction may increase the processivity of the 5'->3' exonuclease
CC activity. Interacts with PCNA, and this interaction may both stimulate
CC the cryptic 3'->5' exonuclease activity and suppress the 5'->3'
CC exonuclease activity. Interacts with WRN, and this interaction
CC stimulates both the 5'->3' exonuclease activity and cleavage of 5'-
CC overhanging flap structures. Interacts with RECQL/RECQ1, and this
CC interaction stimulates cleavage of 5'-overhanging flap structures.

CC DNA replication, probably by ATM or ATR. Phosphorylation at Ser-454,
CC Thr-621 and Ser-714 is induced upon DNA-damage caused by treatment with
CC hydroxyurea (HU) but not upon IR treatment. The HU-induced EXO1 triple
CC phosphorylation facilitates destabilization/degradation of the protein.
CC {ECO:0000269|PubMed:18048416}.
CC -!- POLYMORPHISM: Most naturally occurring variants in this protein are not
CC associated with familial disposition to hereditary non-polyposis
CC colorectal cancer (HNPCC) (PubMed:12517792). Furthermore, germline
CC deletions involving this locus are not associated with clinically
CC manifested colorectal tumors (PubMed:14623461).
CC {ECO:0000269|PubMed:12517792, ECO:0000269|PubMed:14623461}.
CC -!- SIMILARITY: Belongs to the XPG/RAD2 endonuclease family. EXO1
CC subfamily. {ECO:0000305}.
CC -!- SEQUENCE CAUTION:
CC Sequence=AAC33874.1; Type=Frameshift; Evidence={ECO:0000305};
CC -!- WEB RESOURCE: Name=NIEHS-SNPs;
