Termination of nuclear lncRNA transcription promotes mitochondrial genome maintenance

lncrna

Most DNA in the genomes of higher organisms does not code for proteins. RNA Polymerase II (Pol II) transcribes non-coding DNA into long non-coding RNAs (lncRNAs), but biological roles of lncRNA are unclear. Researchers at the University of Copenhagen found that mutations in the yeast lncRNA CUT60 result in poor growth. Defective termination of CUT60 transcription causes read-through transcription across the ...

The short ASCC3 RNA isoform functions as a long non-coding RNA

Researchers from the Francis Crick Institute analyzed the transcription-related DNA damage response on a genome-wide scale with great spatial and temporal resolution. Upon UV irradiation, a slowdown of transcript elongation and restriction of gene activity to the promoter-proximal ∼25 kb is observed. This is associated with a shift from expression of long mRNAs to shorter isoforms, incorporating alternative last exons ...
