Alkylation base damage is converted into repairable double-strand breaks and complex intermediates in G2 cells lacking AP endonuclease.

open access: yesPLoS Genetics, 2011
DNA double-strand breaks (DSBs) are potent sources of genome instability. While there is considerable genetic and molecular information about the disposition of direct DSBs and breaks that arise during replication, relatively little is known about DSBs ...

Recombinational Repair of a Chromosomal DNA Double Strand Break: A Dissertation

open access: yes, 2009
Repairing a chromosomal DNA double strand break is essential for survival and maintenance of genomic integrity of a eukaryotic organism. The eukaryotic cell has therefore evolved intricate mechanisms to counteract all sorts of genomic insults in the ...

Effect of bacterial recA expression on DNA repair in the rad51 and rad52 mutants of Saccharomyces cerevisiae

open access: yesGenetics and Molecular Biology, 1998
Molecular and functional homology between yeast proteins pRad51 and pRad52 and Escherichia coli pRecA involved in recombinational DNA repair led us to investigate possible effects of recA gene expression on DNA repair in rad51 and rad52 mutants of ...

Distinct roles for two RAD51-related genes in Trypanosoma brucei antigenic variation

open access: yes, 2005
In Trypanosoma brucei, DNA recombination is crucial in antigenic variation, a strategy for evading the mammalian host immune system found in a wide variety of pathogens.

Replication and recombination factors contributing to recombination-dependent bypass of DNA lesions by template switch.

open access: yesPLoS Genetics, 2010
Damage tolerance mechanisms mediating damage-bypass and gap-filling are crucial for genome integrity. A major damage tolerance pathway involves recombination and is referred to as template switch.

DNA damage checkpoint and repair centers

open access: yes, 2004
In eukaryotes, recombinational repair is choreographed by multiprotein complexes that are organized into focal assemblies. These foci are highly dynamic giga-dalton structures capable of simultaneously repairing multiple DNA lesions.

The mechanism and evolution of recombinational repair.

open access: yes, 1988
Recently, hydrogen peroxide (H₂O₂), and its free-radical product the hydroxyl radical (OH·), have been identified as major sources of DNA damage in living organisms.

Characterization of a novel human SMC heterodimer homologous to the Schizosaccharomyces pombe Rad18/Spr18 complex [PDF]

open access: yes, 2001
The structural maintenance of chromosomes (SMC) protein encoded by the fission yeast rad18 gene is involved in several DNA repair processes and has an essential function in DNA replication and mitotic control.

Roles of Vertebrate Smc5 in Sister Chromatid Cohesion and Homologous Recombinational Repair

open access: yes, 2011
The structural maintenance of chromosomes (Smc) family members Smc5 and Smc6 are both essential in budding and fission yeasts. Yeast smc5/6 mutants are hypersensitive to DNA damage, and Smc5/6 is recruited to HO-induced double-strand breaks (DSBs ...
