WebThe DNA interstrand crosslink (ICL) is a particularly toxic type of DNA damage that sticks the two strands of the DNA together, making it impossible for the strands to separate. Separation of the DNA strands is necessary for important cellular processes, including gene expression and DNA replication. Webnucleotide target after reversal of the formed ICL. In the last decade, our group has reported on the use of furan modification of oligonucleotides for the realization of DNA–D(R)NA …

WebJun 16, 2024 · In order to fully investigate the effect of the aromatic substituents on DNA ICL formation, we studied the kinetics of DNA cross-linking and determined the reaction rate of these compounds with H 2 O 2 (Table 1). The ICL growth induced by 2a and 5a followed first-order kinetics, which was similar to the parent compound 1a (SI Fig. S13A and B). WebA critical step in ICL repair is the unhooking of the ICL from one of the strands by nucleases followed by translesion synthesis of the unhooked ICL by DNA polymerases.

To repair interstrand crosslinks in eukaryotes, a 3’ flap endonuclease from the NER, XPF-ERCC1, is recruited to the crosslinked DNA, where it assists in ‘unhooking’ the DNA by cleaving the 3’ strand at the crosslink site.
