MRE11A
Double-strand break repair protein MRE11A is a protein that in humans is encoded by the MRE11A gene.[1]
Function
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.[2]
Orthologs of MRE11A
Mre11, an ortholog of human MRE11A, occurs in the prokaryote archaeon Sulfolobus acidocaldarius.[3] In this organism the Mre11 protein interacts with the Rad50 protein and appears to have an active role in the repair of DNA damages experimentally introduced by gamma radiation.[3] Similarly, during meiosis in the eukaryotic protist Tetrahymena Mre11 is required for repair of DNA damages, in this case double-strand breaks,[4] by a process that likely involves homologous recombination. These observations suggest that human MRE11A is descended from prokaryotic and protist ancestral Mre11 proteins that served a role in early processes for repairing DNA damage.
Interactions
MRE11A has been shown to interact with:
- ATM,[5][6]
- BRCA1,[6][7][8][9]
- Ku70,[10]
- MDC1,[11]
- NBN,[6][12][13][14][15]
- Rad50,[6][7][10][12][16] and
- TERF2.[17]
