Transcription can pose a threat to genomic stability through the formation of R-loops that obstruct the progression of replication forks. R-loops are three-stranded nucleic acid structures formed by an RNA-DNA hybrid with a displaced non-template DNA strand. We developed RDProx to identify proteins ...
The RNA helicase DDX41 is a DEAD-box helicase that is well known as a virus sensor in dendritic cells and a tumor suppressor that is frequently mutated in myeloid neoplasms. However, the functions and relevance of DDX41 in solid tumors remain largely unexplored. In this study, through in vivo CRISPR...
Our findings showed that high-expressed DDX41 translocates to the R-loop structure of RPL/RPS genes, accelerating their transcription and promoting ribosome biogenesis. Additionally, acetyltransferase KAT8 is required for H3K9ac modification of the DDX41 promoter, while NR2C1/NR2C2 are responsible f...
Short tracts of trinucleotide repeats with less than 10 repeats are found frequently throughout the genome without any apparent negative impact on DNA replication fork progression or transcription elongation. CGG binding protein 1 (CGGBP1) binds to CGG triplet repeats and has been implicated in mult...
