Lethal and mutagenic properties of MMS-generated DNA lesions in Escherichia coli cells deficient in BER and AlkB-directed DNA repair. [PDF]
Methylmethane sulphonate (MMS), an S(N)2-type alkylating agent, generates DNA methylated bases exhibiting cytotoxic and mutagenic properties. Such damaged bases can be removed by a system of base excision repair (BER) and by oxidative DNA demethylation ...

Human RECQ1 is a DNA damage responsive protein required for genotoxic stress resistance and suppression of sister chromatid exchanges. [PDF]
DNA helicases are ubiquitous enzymes that unwind DNA in an ATP-dependent and directionally specific manner. Unwinding of double-stranded DNA is essential for the processes of DNA repair, recombination, transcription, and DNA replication.

Plant DNA repair and recombination on the French Mediterranean [PDF]
This EMBO Workshop on Plant DNA Repair & Recombination took place between 31 May and 3 June 2007, in Presqu'ile de Giens, France, and was organized by B. Hohn, A. Levy, H. Puchta, D. Shippen, C. Well and C. White. ![][1] Two factors motivate research in plant DNA repair and recombination today: the unique tools that plants offer for understanding ...

Guidelines for DNA recombination and repair studies: Cellular assays of DNA repair pathways [PDF]
Understanding the plasticity of genomes has been greatly aided by assays for recombination, repair and mutagenesis. These assays have been developed in microbial systems that provide the advantages of genetic and molecular reporters that can readily be manipulated. Cellular assays comprise genetic, molecular, and cytological reporters.

Summary: The advance and stability of replication forks rely on a tight co-regulation of DNA synthesis and nucleosome assembly. We show that mutants affected in parental histone recycling are impaired in the recombinational repair of the single-stranded ...

Transcript-RNA-templated DNA recombination and repair [PDF]
Homologous recombination is a molecular process that has multiple important roles in DNA metabolism, both for DNA repair and genetic variation in all forms of life. Generally, homologous recombination involves the exchange of genetic information between two identical or nearly identical DNA molecules; however, homologous recombination can also occur ...

Identification and characterization of MUS81 point mutations that abolish interaction with the SLX4 scaffold protein [PDF]
MUS81-EME1 is a conserved structure-selective endonuclease with a preference for branched DNA substrates in vitro that correspond to intermediates of DNA repair.

BRCA1-BARD1: the importance of being in shape
The breast cancer type-1 susceptibility protein (BRCA1) contributes to genome integrity through homologous recombinational DNA repair and by protecting stalled replication forks from nucleolytic degradation.

Interactome analysis and docking site prediction of DNA X-ray repair cross-complementing protein (XRCC) in Arabidopsis thaliana [PDF]
There are seven homologs in eukaryotic RAD51 gene family which are conserved among animals and plants, and those are RAD51, DMC1, RAD51c, XRCC3, RAD51b, RAD51d and XRCC2.

ATM modulates the loading of recombination proteins onto a chromosomal translocation breakpoint hotspot. [PDF]
Chromosome translocations induced by DNA damaging agents, such as ionizing radiation and certain chemotherapies, alter genetic information resulting in malignant transformation. Abrogation or loss of the ataxia-telangiectasia mutated (ATM) protein, a DNA
