Western blot analysis for MRE11A in 293 cells : 10 ug per lane 293 cell lysate was resolved by SDS-PAGE and the blot was probed with 2 ug/mL MRE11A polyclonal antibody (Cat # PAB0179). A protein band of approximate molecular weight of 81 KDa is detected.
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
