Keeping homologous recombination in check [PDF]

open access: yesCell Research, 2016
Pathway choice is a critical event in the repair of DNA double-strand breaks. In a recent paper published in Nature, Orthwein et al. define a mechanism by which homologous recombination is controlled in G1 cells to favor non-homologous end joining.

Plasmodium falciparum gametogenesis essential protein 1 (GEP1) is a transmission‐blocking target

open access: yesFEBS Letters, EarlyView.
This study shows Plasmodium falciparum GEP1 is vital for activating sexual stages of malarial parasites even independently of a mosquito factor. Knockout parasites completely fail gamete formation even when a phosphodiesterase inhibitor is added. Two single‐nucleotide polymorphisms (V241L and S263P) are found in 12%–20% of field samples.

On a break with the X: the role of repair of double-stranded DNA breaks in X-linked disease [PDF]

open access: yes, 2012
The problem of managing free reactive DNA ends in eukaryotic cells has resulted in the development of a number of mechanisms in order to ensure that free ends are rendered non-reactive, or that the double-strand DNA breaks generating the free ends are ...

Linked dimers of the AAA+ ATPase Msp1 reveal energetic demands and mechanistic plasticity for substrate extraction from lipid bilayers

open access: yesFEBS Letters, EarlyView.
Cells must clear mislocalized or faulty proteins from membranes to survive. The AAA+ ATPase Msp1 performs this task, but dissecting how its six subunits work together is challenging. We engineered linked dimers with varied numbers of functional subunits to reveal how Msp1 subunits cooperate and use energy to extract proteins from the lipid bilayer ...

The Influence of Homologous Arm Length on Homologous Recombination Gene Editing Efficiency Mediated by SSB/CRISPR-Cas9 in Escherichia coli

open access: yesMicroorganisms
The precise editing of genes mediated by CRISPR-Cas9 necessitates the application of donor DNA with appropriate lengths of homologous arms and fragment sizes.

DNA DSB repair pathway choice: an orchestrated handover mechanism [PDF]

open access: yes, 2014
DNA double strand breaks (DSBs) are potential lethal lesions but can also lead to chromosome rearrangements, a step promoting carcinogenesis. DNA non-homologous end-joining (NHEJ) is the major DSB rejoining process and occurs in all cell cycle stages ...

Rad27/FEN1 prevents accumulation of Okazaki fragments and ribosomal DNA copy number changes

open access: yesFEBS Letters, EarlyView.
The budding yeast Rad27 is a structure‐specific endonuclease. Here, the authors reveal that Rad27 is crucial for maintaining the stability of the ribosomal RNA gene (rDNA) region. Rad27 deficiency leads to the accumulation of Okazaki fragments and changes in rDNA copy number.

RAPID SOUTHERN BLOT PROTOCOL FOR THE ANALYSIS OF TARGETED MUTAGENESIS IN THE MOUSE IGHG1 LOCUS

open access: yesScientific Papers Animal Science and Biotechnologies, 2023
The efficiency of homologous recombination relies on the lenght of the homology arms and the chromatin compactation of the locus. In ES cells the immuoglobulin locu is compacted. Thus, the homologous recombination events occur at a very low frequency.

Replication dynamics of recombination-dependent replication forks

open access: yesNature Communications, 2021
Replication forks that are stalled at obstacles on the DNA template can be restarted by homologous recombination. Here, the authors show replication dynamics during homologous recombination-dependent replication fork restart by combining polymerase usage

Regulation of Homologous Recombination in Eukaryotes [PDF]

open access: yesAnnual Review of Genetics, 2010
Homologous recombination (HR) is required for accurate chromosome segregation during the first meiotic division and constitutes a key repair and tolerance pathway for complex DNA damage, including DNA double-strand breaks, interstrand crosslinks, and DNA gaps.
