Anti-Mre11 Antibody

Mre11 is a component of the MRN complex (Mre11/Rad50/Nbs1), which plays a central role in double-strand break (DSB) repair, DNA recombination, maintenance of telomere integrity and meiosis. The complex possesses single-strand endonuclease activity and double-strand-specific 3'-5' exonuclease activity, which are provided by MRE11A. RAD50 may be required to bind DNA ends and hold them close. This could facilitate searches for short or long regions of sequence homology in the recombining DNA templates, and may also stimulate the activity of DNA ligases and/or restrict the nuclease activity of MRE11A to prevent nucleolytic degradation past a given point. The complex may also be required for DNA damage signaling via activation of the ATM kinase. In telomeres, the MRN complex may modulate t-loop formulation. Anti-Mre11 Antibody is useful for researcher interested in DNA Damage and Repair and Nuclear Signaling Research.

This affinity purified antibody was prepared from whole rabbit serum produced by repeated immunizations with a recombinant protein corresponding to amino acids 68-706 of mouse Mre11 protein.

This affinity purified antibody is directed against mouse Mre11 protein. The product was affinity purified from monospecific antiserum by immunoaffinity purification. A BLAST analysis was used to suggest cross-reactivity with Mre11 protein from rat (94% homology) . Based on protein sequence homology also expect partial reactivity against Mre11 homologues from macaque (88%), human (84%) and dog (82%) . This sequence shows less than 75% homology to homologues from bovine, Xenopus, chicken, chimpanzee and zebrafish sources. Reactivity against homologues from other sources is not known.

The complex possesses single-strand endonuclease activity and double-strand- specific 3'-5' exonuclease activity, which are provided by MRE11A. RAD50 may be required to bind DNA ends and hold them in close proximity. This could facilitate searches for short or long regions of sequence homology in the recombining DNA templates, and may also stimulate the activity of DNA ligases and/or restrict the nuclease activity of MRE11A to prevent nucleolytic degradation past a given point (PubMed:9651580, PubMed:9590181, PubMed:9705271, PubMed:11741547) . The complex may also be required for DNA damage signaling via activation of the ATM kinase (PubMed:15064416) . In telomeres the MRN complex may modulate t- loop formation (PubMed:10888888) .
