Recombination: Homologous recombination branches out [PDF]

Current Biology, 2001
Homologous recombination can be divided into three key steps: strand exchange, branch migration and resolution. The identification of a protein complex that catalyses branch migration and Holliday junction resolution argues that the mechanism of homologous recombination is conserved from bacteria to man.

Homologous Recombination as a Replication Fork Escort: Fork-Protection and Recovery

Biomolecules, 2012
Homologous recombination is a universal mechanism that allows DNA repair and ensures the efficiency of DNA replication. The substrate initiating the process of homologous recombination is a single-stranded DNA that promotes a strand exchange reaction ...

Homologous Recombination in Negative Sense RNA Viruses

Viruses, 2011
Recombination is an important process that influences biological evolution at many different levels. More and more homologous recombination events have been reported among negative sense RNA viruses recently.

Sister chromatid exchanges induced by perturbed replication can form independently of BRCA1, BRCA2 and RAD51

Nature Communications, 2022
Sister chromatid exchanges (SCEs) are considered to be products of homologous recombination repair. The authors show that SCEs can arise independently of homologous recombination due to processing of replication intermediates during mitosis.

No observed effect of homologous recombination on influenza C virus evolution

Virology Journal, 2010
The occurrence of homologous recombination in influenza viruses has been under some debate recently. To determine the extent of homologous recombination in influenza C virus, recombination analyses of all available gene sequences of influenza C virus ...

Regulation Mechanisms of Meiotic Recombination Revealed from the Analysis of a Fission Yeast Recombination Hotspot ade6-M26

Biomolecules, 2022
Meiotic recombination is a pivotal event that ensures faithful chromosome segregation and creates genetic diversity in gametes. Meiotic recombination is initiated by programmed double-strand breaks (DSBs), which are catalyzed by the conserved Spo11 ...

Mouse WRN Helicase Domain Is Not Required for Spontaneous Homologous Recombination-Mediated DNA Deletion

Journal of Nucleic Acids, 2010
Werner syndrome is a rare disorder that manifests as premature aging and age-related diseases. WRN is the gene mutated in WS, and is one of five human RecQ helicase family members.

Improved Gene Targeting through Cell Cycle Synchronization. [PDF]

PLoS ONE, 2015
Gene targeting is a challenge in organisms where non-homologous end-joining is the predominant form of recombination. We show that cell division cycle synchronization can be applied to significantly increase the rate of homologous recombination during ...

Using single loxP sites to enhance homologous recombination: ts mutants in Sec1 of Dictyostelium discoideum.

PLoS ONE, 2007
BackgroundDictyostelium discoideum amoebae are haploid and, as they share many features with animal cells, should be an ideal creature for studying basic processes such as cell locomotion.

BRCA2 and homologous recombination [PDF]

Breast Cancer Research, 2001
Two recent papers provide new evidence relevant to the role of the breast cancer susceptibility gene BRCA2 in DNA repair. Moynahan et al provide genetic data indicating a requirement for BRCA2 in homology-dependent (recombinational) repair of DNA double-strand breaks.
