Description
Product Characteristics:
Mre11 is a component of the MRN complex, which plays a critical role in double-strand break repair (DSB), DNA recombination, maintenance of telomere integrity, and meiosis. Mre11 has both single-strand endonuclease and double strand-specific 3'-5' exonuclease activities. Rad50, another component of the MRN complex, is postulated to bind to DNA ends and hold them in close proximity, thus facilitating searches for regions of sequence homology, and also possibly stimulating the activity of DNA ligases and/or restricting Mre11 activity. Mutations in Mre11 may cause breast cancer.

Target Information: 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]
