Human mitochondrial degradosome prevents harmful mitochondrial R loops and mitochondrial genome instability
(2018)
R loops are nucleic acid structures comprising an DNA-RNA hybrid and a displaced single-stranded DNA. These structures may occur transiently during transcription, playing essential biological functions. However, persistent ...

The yeast and human FACT chromatin-reorganizing complexes resolve R-loop-mediated transcription-replication conflicts
(Cold Spring Harbor Laboratory Press, 2014)
FACT (facilitates chromatin transcription) is a chromatin-reorganizing complex that swaps nucleosomes around the RNA polymerase during transcription elongation and has a role in replication that is not fully understood ...

The Npl3 hnRNP prevents R-loop-mediated transcription–replication conflicts and genome instability
(Cold Spring Harbor Laboratory Press, 2013)
Transcription is a major obstacle for replication fork (RF) progression and a cause of genome instability. Part of this instability is mediated by cotranscriptional R loops, which are believed to increase by suboptimal ...
