Artemis (protein)
View/Edit Human | View/Edit Mouse |
Artemis is a protein that in humans is encoded by the DCLRE1C (DNA cross-link repair 1C) gene.[5][6]
Function
Artemis is a nuclear protein that is involved in V(D)J recombination and DNA repair. The protein has endonuclease activity on 5' and 3' overhangs and hairpins when complexed with PRKDC.[7]
Immune response
Artemis plays an essential role in
Repair of DNA breaks
Cells deficient in Artemis are more sensitive than normal cells to X‑rays[5] and to chemical agents that induce double-strand breaks (DSBs),[10] and they show a higher incidence of chromosome breaks following irradiation.[11] Direct measurement of DSBs by pulsed-field electrophoresis indicates that in Artemis-deficient cells 75-90% of DSBs are repaired rapidly, just as in normal cells. However, the remaining 10-20% of DSBs that are repaired more slowly (2-24 hr) in normal cells, are not repaired at all in Artemis-deficient cells.[12] Repair of these presumably difficult-to-rejoin breaks also requires several other proteins, including the Mre11/Rad50/NBS1 complex, the ataxia telangiectasia mutated ATM kinase, and 53BP1. Because Artemis can remove damaged ends from DNA,[10] it has been proposed that these DSBs are those whose damaged ends require trimming by Artemis. However, evidence that both ATM and Artemis are specifically required for repair of DSBs in heterochromatin,[13][14] has called this interpretation into question.

Clinical significance
Mutations in this gene cause Athabascan-type severe combined immunodeficiency (SCIDA).[16]
