OverviewNCBI Gene
This gene encodes a nuclear protein involved in homologous recombination, telomere length maintenance, and DNA double-strand break repair. By itself, the protein has 3' to 5' exonuclease activity and endonuclease activity. The protein forms a complex with the RAD50 homolog; this complex is required for nonhomologous joining of DNA ends and possesses increased single-stranded DNA endonuclease and 3' to 5' exonuclease activities. In conjunction with a DNA ligase, this protein promotes the joining of noncomplementary ends in vitro using short homologies near the ends of the DNA fragments. This gene has a pseudogene on chromosome 3. Alternative splicing of this gene results in two transcript variants encoding different isoforms. [provided by RefSeq, Jul 2008]

Antibody and autoantibody relevanceSeroatlas analysis
Seroatlas reads MRE11 as an antibody target. Whether an autoantibody or antibody against MRE11 could matter depends on whether native MRE11 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.
MRE11 is annotated as predominantly intracellular. Intracellular proteins are common autoantibody markers, becoming visible to the immune system after cell injury or altered processing, but are usually markers of disease rather than direct drivers.
Annotation status
The present source text does not explicitly label MRE11 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
