Integrative AUF1 PAR-CLIP analysis uncovers AUF1 roles in translation and genome integrity (RNA-Seq 2)

We report that AUF1 modulates global mRNA stability and translation, in turn promoting the maintenance of DNA integrity. Overall design: Please see individual series. In short, for AUF1 PAR-CLIP, the four isoforms of AUF1 (p37, p40, p42, and p45) tagged with a Flag epitope were expressed in HEK293 cells. For total RNA-Seq HEK293 cells were transfected with Control siRNA, AUF1 siRNA, Empty Vector, Flag-AUF1 p37, p40, p42, or p45 as well as WI-38 cells were collected at PDL 15 and 55 and also transfected with Control siRNA, AUF1 siRNA, HuR siRNA. For Ribo-Seq HeLa cells were transfected with Control siRNA, AUF1 siRNA, or HuR siRNA.
