+== Function ==
+[https://www.uniprot.org/uniprot/EXO1_HUMAN EXO1_HUMAN] 5'->3' double-stranded DNA exonuclease which may also possess a cryptic 3'->5' double-stranded DNA exonuclease activity. Functions in DNA mismatch repair (MMR) to excise mismatch-containing DNA tracts directed by strand breaks located either 5' or 3' to the mismatch. Also exhibits endonuclease activity against 5'-overhanging flap structures similar to those generated by displacement synthesis when DNA polymerase encounters the 5'-end of a downstream Okazaki fragment. Required for somatic hypermutation (SHM) and class switch recombination (CSR) of immunoglobulin genes. Essential for male and female meiosis.<ref>PMID:10364235</ref> <ref>PMID:10608837</ref> <ref>PMID:11809771</ref> <ref>PMID:11842105</ref> <ref>PMID:12414623</ref> <ref>PMID:12704184</ref> <ref>PMID:14636568</ref> <ref>PMID:14676842</ref> <ref>PMID:15225546</ref> <ref>PMID:15886194</ref> <ref>PMID:16143102</ref> <ref>PMID:9685493</ref>
