Homologous Recombination: Down to the Wire [PDF]

open access: yesCurrent Biology, 2004
Exchange of strands between homologous DNA molecules is catalyzed by evolutionarily conserved recombinases. These proteins can occur in different quaternary arrangements: rings or helical filaments. Recent results reveal that recombinase function follows from the filamentous form.

m5C modification of mRNA serves a DNA damage code to promote homologous recombination

open access: yesNature Communications, 2020
Recruitment of DNA repair proteins to DNA damage sites is a critical step for DNA repair. Post-translational modifications of proteins at DNA damage sites serve as DNA damage codes to recruit specific DNA repair factors.

Double-strand break repair and homologous recombination in Schizosaccharomyces pombe [PDF]

open access: yes, 2006
In recent years our understanding of double strand break repair and homologous recombination in Schizosaccharomyces pombe has increased significantly, and the identification of novel pathways and genes with homologues in higher eukaryotes has increased ...

Homologous recombination and its regulation [PDF]

open access: yesNucleic Acids Research, 2012
Homologous recombination (HR) is critical both for repairing DNA lesions in mitosis and for chromosomal pairing and exchange during meiosis. However, some forms of HR can also lead to undesirable DNA rearrangements. Multiple regulatory mechanisms have evolved to ensure that HR takes place at the right time, place and manner. Several of these impinge on

PALB2 self-interaction controls homologous recombination. [PDF]

open access: yes, 2012
PALB2 is essential for BRCA2 anchorage to nuclear structures and for homologous recombinational repair of DNA double-strand breaks. Here, we report that the N-terminal coiled-coil motif of PALB2 regulates its self-association and homologous recombination.

Intermolecular Homologous Recombination in Plants [PDF]

open access: yesMolecular and Cellular Biology, 1990
To study DNA topological requirements for homologous recombination in plants, we have constructed pairs of plasmids that contain nonoverlapping deletions in the neomycin phosphotransferase gene [APH(3')II], which, when intact, confers kanamycin resistance to plant cells.

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

open access: yesBiomolecules, 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 ...

High fidelity of RecA-catalyzed recombination: a watchdog of genetic diversity [PDF]

open access: yes, 2006
Homologous recombination plays a key role in generating genetic diversity, while maintaining protein functionality. The mechanisms by which RecA enables a single-stranded segment of DNA to recognize a homologous tract within a whole genome are poorly ...

Dependence of frequency of homologous recombination on the homology length. [PDF]

open access: yesGenetics, 1995
Abstract The frequency of homologous recombination is believed to be a linear function of the length (N bp) of homology between DNAs. Here, the N intercept is believed to be determined by a threshold length below which some physical constraint is effective.

Homologous Recombination in Negative Sense RNA Viruses

open access: yesViruses, 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.
