Application Abreviews Notes
ELISA 1/10000.

ICC/IF 1/500 - 1/1000.


  • Function5'->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.
  • Tissue specificityHighly expressed in bone marrow, testis and thymus. Expressed at lower levels in colon, lymph nodes, ovary, placenta, prostate, small intestine, spleen and stomach.
  • Sequence similaritiesBelongs to the XPG/RAD2 endonuclease family. EXO1 subfamily.
  • Developmental stageHighly expressed in fetal liver and at lower levels in fetal brain, heart, kidney, spleen and thymus.
  • Post-translational
    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.
  • Cellular localizationNucleus. Colocalizes with PCNA to discrete nuclear foci in S-phase.
