RNase H enables efficient repair of R-loop induced DNA damage. [PDF]
, 2016 R-loops, three-stranded structures that form when transcripts hybridize to chromosomal DNA, are potent agents of genome instability. This instability has been explained by the ability of R-loops to induce DNA damage. Here, we show that persistent R-loops

DNA charge transport as a first step in coordinating the detection of lesions by repair proteins [PDF]
, 2012 Damaged bases in DNA are known to lead to errors in replication and transcription, compromising the integrity of the genome. We have proposed a model where repair proteins containing redox-active [4Fe-4S] clusters utilize DNA charge transport (CT) as a ...

Biomolecular Concepts, 2020 Liquid-liquid phase separation (LLPS) is a way to concentrate biochemical reactions while excluding noninteracting components. Disordered domains of proteins, as well as interaction with RNA, favor condensation but are not mandatory for modulating this ...

Repair, abort, ignore? Strategies for dealing with UV damage [PDF]
, 2011 DNA repair is a prominent member of the nuclear transactions triad (replication, transcription, and repair). Sophisticated mechanisms govern the cellular process of decision-making (to repair or not to repair, to proceed with cell cycle or not and ...

Personalized genome structure via single gamete sequencing
Genome Biology, 2021 Genetic maps have been fundamental to building our understanding of disease genetics and evolutionary processes. The gametes of an individual contain all of the information required to perform a de novo chromosome-scale assembly of an individual’s genome,

High-resolution mapping of heteroduplex DNA formed during UV-induced and spontaneous mitotic recombination events in yeast. [PDF]
, 2017 In yeast, DNA breaks are usually repaired by homologous recombination (HR). An early step for HR pathways is formation of a heteroduplex, in which a single-strand from the broken DNA molecule pairs with a strand derived from an intact DNA molecule.

Tyrosine dephosphorylation of H2AX modulates apoptosis and survival decisions. [PDF]
, 2009 Life and death fate decisions allow cells to avoid massive apoptotic death in response to genotoxic stress. Although the regulatory mechanisms and signalling pathways controlling DNA repair and apoptosis are well characterized, the precise molecular ...

RanBP2-Mediated SUMOylation Promotes Human DNA Polymerase Lambda Nuclear Localization and DNA Repair [PDF]
, 2020 Cellular DNA is under constant attack by a wide variety of agents, both endogenous and exogenous. To counteract DNA damage, human cells have a large collection of DNA repair factors. Among them, DNA polymerase lambda (Polλ) stands out for its versatility,
