Recombination: Homologous recombination branches out [PDF]
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.

The many facets of homologous recombination at telomeres [PDF]
The ends of linear chromosomes are capped by nucleoprotein structures called telomeres. A dysfunctional telomere may resemble a DNA double-strand break (DSB), which is a severe form of DNA damage. The presence of one DSB is sufficient to

Homologous recombination deficiency among patients with germline or somatic non-BRCA1/2 homologous recombination repair gene variations [PDF]
This study examined the relationship between homologous recombination deficiency (HRD) and variations in non-BRCA1/2 homologous recombination repair (HRR) genes.

Homologous recombination risk in baculovirus expression vector system
The baculovirus expression vector system (BEVS) is widely used for producing recombinant proteins. To achieve high expression level of recombinant proteins, baculoviral elements, such as enhancers, promoters, signal peptide coding sequences and 3′-UTR ...

Multi-scale characterisation of homologous recombination deficiency in breast cancer
Background Homologous recombination is a robust, broadly error-free mechanism of double-strand break repair, and deficiencies lead to PARP inhibitor sensitivity.

BRCA2 and homologous recombination [PDF]
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.

Slow Replication Fork Velocity of Homologous Recombination-Defective Cells Results from Endogenous Oxidative Stress. [PDF]
Replications forks are routinely hindered by different endogenous stresses. Because homologous recombination plays a pivotal role in the reactivation of arrested replication forks, defects in homologous recombination reveal the initial endogenous stress ...

Homologous Recombination: Down to the Wire [PDF]
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.
