| Title | The immediate impact of exoribonucleolysis on nuclear RNA processing, turnover and transcriptional control revealed by rapid depletion of DIS3, EXOSC10 or XRN2 from human cells |

| Experimental Design | Nuclear RNA-seq was performed on an auxin-inducible degron (AID) tagged cell lines in treated with or without auxin inducing rapid depletion of EXOSC10 or DIS3 protein. HCT116 cells also ectopically express TIR1 from a sleeping beauty transposon integrated cassette. AID incorporated proteins contain in-frame insertion of AID tag, P2A cleavage site, antibiotic resistance marker and SV40 polyA site. Two repair templates expressing different antibiotic resistance markers (neomycin and hygromycin) were used to ensure biallelic intersion of the repair cassette using CRISPR/Cas9. We also performed individual nucleotide cross-linking and immunoprecipitation (iCLIP) on a catalytic mutant of EXOSC10 (D313N), in order to complement a previous iCLIP experiment using EXOSC10 WT. We reasoned that by using a catalytic mutant of EXOSC10 we would be able to stabilize interactions between the exoribonuclease and it global RNA substrates. In the process we identified 30nt footprints of iCLIP density downstream of pre-rRNAs and pre-snoRNAs exclusively seen in EXOSC10 CAT CLIP profiles. |
