WebMoreover, polκ bypasses an abasic site andN-2–acetylaminofluorene (AAF)-adduct in an error-prone manner but does not bypass a cis–syn or (6-4) thymine–thymine dimer or a cisplatin-adduct. Therefore, our results implicate an important role for polκ in the mutagenic bypass of certain types of DNA lesions. Keywords.
