Summaries for EXO1 Gene

Entrez Gene Summary for EXO1 Gene

  • This gene encodes a protein with 5' to 3' exonuclease activity as well as an RNase H activity. It is similar to the Saccharomyces cerevisiae protein Exo1 which interacts with Msh2 and which is involved in mismatch repair and recombination. Alternative splicing of this gene results in three transcript variants encoding two different isoforms. [provided by RefSeq, Jul 2008]

GeneCards Summary for EXO1 Gene

EXO1 (Exonuclease 1) is a Protein Coding gene. Diseases associated with EXO1 include Chilblain Lupus and Xeroderma Pigmentosum, Group G. Among its related pathways are Cell Cycle Checkpoints and Gene Expression. GO annotations related to this gene include nuclease activity and RNA-DNA hybrid ribonuclease activity.

UniProtKB/Swiss-Prot for EXO1 Gene

  • 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.

Interacts with the MSH2-MSH6 heterodimer via MSH2, and this interaction may increase the processivity of the 5->3 exonuclease activity. Interacts with PCNA, and this interaction may both stimulate the cryptic 3->5 exonuclease activity and suppress the 5->3 exonuclease activity. Interacts with WRN, and this interaction stimulates both the 5->3 exonuclease activity and cleavage of 5-overhanging flap structures. Interacts with RECQL/RECQ1, and this interaction stimulates cleavage of 5-overhanging flap structures.

Post-translational modifications for EXO1 Gene

  • Phosphorylated upon DNA damage and in response to agents stalling DNA replication, probably by ATM or ATR. Phosphorylation at Ser-454, Thr-621 and Ser-714 is induced upon DNA-damage caused by treatment with hydroxyurea (HU) but not upon IR treatment. The HU-induced EXO1 triple phosphorylation facilitates destabilisation/degradation of the protein.
