The S-phase checkpoint is required to respond to R-loops accumulated in THO mutants
(American Society for Microbiology, 2009)
Cotranscriptional R-loops are formed in yeast mutants of the THO complex, which functions at the interface between transcription and mRNA export. Despite the relevance of R-loops in transcription-associated recombination, the ...

Yeast Sen1 helicase protects the genome from transcription-associated instability
(Elsevier, 2011-01-06)
Sen1 of S. cerevisiae is a known component of the NRD complex implicated in transcription termination of nonpolyadenylated as well as some polyadenylated RNA polymerase II transcripts. We now show that Sen1 helicase possesses ...

A role for the Saccharomyces cerevisiae Rtt109 histone acetyltransferase in R-loop homeostasis and associated genome instability
(Genetics Society of America, 2022)
The stability of the genome is occasionally challenged by the formation of DNA-RNA hybrids and R-loops, which can be influenced by the chromatin context. This is mainly due to the fact that DNA-RNA hybrids hamper the ...

RNA biogenesis and RNA metabolism factors as R-loop suppressors: a hidden role in genome integrity.
(Cold Spring Harbor Laboratory Press, 2024-07)
Genome integrity relies on the accuracy of DNA metabolism, but as appreciated for more than four decades, transcription enhances mutation and recombination frequencies. More recent research provided evidence for a previously ...
