HuR target mRNAs showing altered expression after DNA damage. Partial list of HuR target mRNAs encoding proteins that change following DNA damage (first column), the region of interaction with HuR (second column), and the genotoxic damage that was shown to affect HuR regulation of the mRNA (third column); “n.r.”: no reported. The HuR kinases linked to the regulation of the mRNAs in the first column are indicated (fourth column).
