WebNov 8, 2024 · The GRF motifs are not necessary for its DNA glycosylase activity, but they mediate the recruitment of NEIL3 to replication forks converged at an ICL (Liu et al., 2010). Recent studies indicate that NEIL3 GRF motifs have an autoinhibitory effect of the glycosylase activity and also inhibit its APE1 endonuclease activity on ssDNA ( Ha et al., … WebApr 14, 2024 · Moreover, these patients are also at an increased risk of internal tumours, likely due to impaired NER of endogenously induced DNA lesions [34]. 2) ICL repair is also substrate of NER. Authors have not discussed it. Author response: As suggested by the reviewer, we have included ICL repair in the revised manuscript as below (lines 138-139):

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. WebDec 1, 2024 · The inter-strand crosslink (ICL), a covalent linkage between both strands of the double helix ( Dronkert and Kanaar, 2001 ), is among the most dangerous type of …
Crosslinked DNA is repaired in cells by a combination of enzymes and other factors from the nucleotide excision repair (NER) pathway, homologous recombination, and the base excision repair (BER) pathway. 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. The 5’ strand is then cleaved, either by XPF-ERCC1 o… WebOct 1, 2004 · DNA interstrand crosslinks (ICLs) are highly toxic DNA lesions, and induce cell death by blocking DNA strands separation.
