The Beli lab collaborated with the Roukos, Luke and Barau lab to identify a novel player in R-loop regulation

R loops, three stranded nucleic acid structures, can pose a threat to genome stability. A great collaborative efforts between multiple CRC members and associated members analysed the R-loop proximal proteome and revealed a role of the tumour suppressor DDX41 in regulating these transcription-induced structures. They could show that DDX41 opposes the formation of R-loops and double strand-break accumulation in promotor regions. These findings could provide a molecular mechanism underlying the genetic predisposition to acute myeloid leukemia in individuals with non-functional DDX41. Read the full paper here.
