The RNA processing exosome is linked to elongating RNA polymerase II in Drosophila

The RNA polymerase II elongation complex contains several factors that facilitate transcription elongation and catalyse the processing of precursor messenger RNAs (pre-mRNAs). The conserved elongation factor Spt6 is recruited rapidly and robustly to sites of active transcription. Here we show that Drosophila Spt6 (dSpt6) co-purifies with the exosome, a… (More)
