Aquarius helicase facilitates HIV-1 integration into R-loop enriched genomic regions - Nature Microbiology

R-loops formed by RNA hybridization to DNA template strand during transcription influence HIV-1 integration into the CD4+ T cell genome. The unwinding of R-loops by splicing helicase Aquarius facilitates integration into speckle-associated domains.

pEGFP-RNASEH1 expresses the nuclear isoform of human RNase H1 with a C-terminal GFP tag

It seems to be most popular with labs working on #Rloops, because RNase H1 acts on RNA:DNA hybrids and overexpression can reduce R-loops
