Aberrant repair initiated by mismatch-specific thymine-DNA glycosylases provides a mechanism for the mutational bias observed in CpG islands

Talhaoui, Ibtissam; Couve, Sophie; Gros, Laurent; Ishchenko, Alexander A.; Matkarimov, Bakhyt; Saparbaev, Murat K. (Nucleic Acids Research, 2014-04-01)

The human thymine-DNA glycosylase (TDG) initiates the base excision repair (BER) pathway to remove spontaneous and induced DNA base damage. It was first biochemically characterized for its ability to remove T mispaired ...
Oxidatively Generated Guanine(C8)-Thymine(N3) Intrastrand Cross-links in Double-stranded DNA Are Repaired by Base Excision Repair Pathways*

Talhaoui, Ibtissam; Shafirovich, Vladimir; Liu, Zhi; Saint-Pierre, Christine; Akishev, Zhiger; Matkarimov, Bakhyt T.; Gasparutto, Didier; Geacintov, Nicholas E.; Saparbaev, Murat (The Journal of Biological Chemistry, 2015-04-15)

Oxidatively generated guanine radical cations in DNA can undergo various nucleophilic reactions including the formation of C8-guanine cross-links with adjacent or nearby N3-thymines in DNA in the presence of O2. The ...
