a Protein lysates from EXD2+/+, EXD2−/−-cl1, EXD2−/− + EXD2WT-cl1 and EXD2−/− + EXD2D108A/E110A-cl1 cells were immuno-blotted for proteins as indicated. Molecular mass of the proteins is indicated (kDa). Source data are provided as a Source Data file. b Cells were mock- or UV-irradiated (15 J/m2) and mRNA was labeled with EU at the indicated time points post-UV. EU signal was quantified by ImageJ and relative integrated densities, normalized to mock-treated level set to 100%, are reported on the graph (n = at least 20 cells per conditions). Red bars indicate mean integrated density. RT recovery time. One-way ANOVA with post-hoc Tukey adjustment comparisons were used to determine the p-values. Source data are provided as a Source Data file. c Representative confocal images of EXD2−/− + EXD2WT-cl1 and EXD2−/− + EXD2D108A/E110A-cl1 treated like in b. Images of the cells were obtained with the same microscopy system and constant acquisition parameters.
