== Disease ==
[https://www.uniprot.org/uniprot/FAN1_HUMAN FAN1_HUMAN] Karyomegalic interstitial nephritis. The disease is caused by mutations affecting the gene represented in this entry.
== Function ==
[https://www.uniprot.org/uniprot/FAN1_HUMAN FAN1_HUMAN] Nuclease required for maintenance of chromosomal stability. Plays a key role in DNA repair of DNA interstrand cross-links (ICL) by being recruited to sites of DNA damage by monoubiquitinated FANCD2. Specifically involved in repair of ICL-induced DNA breaks by being required for efficient homologous recombination, possibly in the resolution of homologous recombination intermediates. Not involved in DNA double-strand breaks resection. Has both endonuclease activity toward 5'-flaps and 5'-exonuclease activity: may act in concert with the 3'-flap-specific enzymes to unhook the ICL by cleaving the lagging-strand template.<ref>PMID:20603015</ref> <ref>PMID:20603016</ref> <ref>PMID:20603073</ref> <ref>PMID:20671156</ref>
