Gene Information

human ... MRE11(4361), MRE11A(4361)

General description

MISSION esiRNA are endoribonuclease prepared siRNA. They are a heterogeneous mixture of siRNA that all target the same mRNA sequence. These multiple silencing triggers lead to highly-specific and effective gene silencing.

Biochem/physiol Actions

MRE11A (meiotic recombination 11 homolog A) is a nuclease which forms complex with Rad50 (DNA repair protein) and Nbs1 (nijmegen breakage syndrome protein 1). This complex works as a sensor of DNA double strand breaks, and is involved in DNA repair processes and DNA damage response. Absence of the complex activity causes developmental and/or degenerative neuronal disorders. In homologous recombination repair, MRE11A is responsible for the 3′-to-5′ exonuclease activity, leading to the generation of protruding 3′ ssDNA at double strand breaks. MRE11A is also an oncoprotein which is associated with colorectal cancer and malignant breast cancer. Hypomorphic mutations in this gene leads to Ataxia-Telangiectasia like disorder.

The MRE11/RAD50/NBS1 (MRN) complex is a major sensor of DNA double strand breaks, whose role in controlling faithful DNA replication and preventing replication stress is also emerging. Inactivation of the MRN complex invariably leads to developmental and/or degenerative neuronal defects...

Ataxia-telangiectasia mutated (ATM) is needed for the initiation of the double-strand break (DSB) repair by homologous recombination (HR). ATM triggers DSB end resection by stimulating the nucleolytic activity of CtIP and MRE11 to generate 3'-ssDNA overhangs, followed by RPA loading...

The resolution of joint molecules that link recombining sister chromatids is essential for chromosome segregation. Here, we determine the fate of unresolved recombination intermediates arising in cells lacking two nucleases required for resolution (GEN1 -/- knockout cells depleted of MUS81)....
