Generation of cell lines expressing different forms of polβ. (A) Structure of the polβ protein used. The different proteins are expressed in the CHO-DRA10 cell line and the corresponding derivative cell lines are listed on the right. From the top to the bottom, the WT form (pIβ4, pIβ15, pBβ20 and pBβ11), the 8 kDa form (dRP5 and dRP10), the 14 kDa form (DN14-11 and DN14-15) and the full length form with the D256A mutation (BMUT8 and BMUT9) (B) Expression of the different forms of polβ were analysed by western blotting.
