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 ...

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.

Recombination in enteroviruses is a biphasic replicative process involving the generation of greater-than genome length 'imprecise' intermediates [PDF]

, 2014
Recombination in enteroviruses provides an evolutionary mechanism for acquiring extensive regions of novel sequence, is suggested to have a role in genotype diversity and is known to have been key to the emergence of novel neuropathogenic variants of ...

Homologous Recombination: To Fork and Beyond [PDF]

Genes, 2018
Accurate completion of genome duplication is threatened by multiple factors that hamper the advance and stability of the replication forks. Cells need to tolerate many of these blocking lesions to timely complete DNA replication, postponing their repair for later. This process of lesion bypass during DNA damage tolerance can lead to the accumulation of

Homologous Recombination and the Formation of Complex Genomic Rearrangements [PDF]

, 2019
International audienceThe maintenance of genome integrity involves multiple independent DNA damage avoidance and repair mechanisms. However, the origin and pathways of the focal chromosomal reshuffling phenomena collectively referred to as chromothripsis

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 ...

NF-κB regulates DNA double-strand break repair in conjunction with BRCA1-CtIP complexes [PDF]

, 2011
NF-κB is involved in immune responses, inflammation, oncogenesis, cell proliferation and apoptosis. Even though NF-κB can be activated by DNA damage via Ataxia telangiectasia-mutated (ATM) signalling, little was known about an involvement in DNA repair ...

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.

Non-Contiguous Protein Recombination [PDF]

, 2013
Swapping sequence elements among related proteins can produce chimeric proteins with novel behaviors and improved properties such as enhanced stability. Although homologous mutations are much more conservative than random mutations, chimeras of distantly-

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 ...
