Spatial and temporal cellular responses to single-strand breaks in human cells [PDF]
, 2003 DNA single-strand breaks (SSB) are one of the most frequent DNA lesions produced by reactive oxygen species and during DNA metabolism, but the analysis of cellular responses to SSB remains difficult due to the lack of an experimental method to produce ...

Data in Brief, 2016 The global genome nucleotide excision repair factor XPC firstly detects DNA lesions and then recruits a ten-subunit complex TFIIH through binding to the subunit p62 to unwind the damaged DNA for excision repair.

Effects of replication domains on genome-wide UV-induced DNA damage and repair.
PLoS Genetics, 2022 Nucleotide excision repair is the primary repair mechanism that removes UV-induced DNA lesions in placentals. Unrepaired UV-induced lesions could result in mutations during DNA replication. Although the mutagenesis of pyrimidine dimers is reasonably well

How chromatin is remodelled during DNA repair of UV-induced DNA damage in Saccharomyces cerevisiae.
PLoS Genetics, 2011 Global genome nucleotide excision repair removes DNA damage from transcriptionally silent regions of the genome. Relatively little is known about the molecular events that initiate and regulate this process in the context of chromatin.

Base Flipping in Nucleotide Excision Repair [PDF]
Journal of Biological Chemistry, 2006 UvrB, the ultimate damage-binding protein in bacterial nucleotide excision repair is capable of binding a vast array of structurally unrelated lesions. A beta-hairpin structure in the protein plays an important role in damage-specific binding. In this paper we have monitored DNA conformational alterations in the UvrB-DNA complex, using the fluorescent ...

Structure and stereochemistry of the base excision repair glycosylase MutY reveal a mechanism similar to retaining glycosidases. [PDF]
, 2015 MutY adenine glycosylases prevent DNA mutations by excising adenine from promutagenic 8-oxo-7,8-dihydroguanine (OG):A mismatches. Here, we describe structural features of the MutY active site bound to an azaribose transition state analog which indicate a

RAD6-RAD18-RAD5-pathway-dependent tolerance to chronic low-dose ultraviolet light [PDF]
, 2009 In nature, organisms are exposed to chronic low- dose ultraviolet light ( CLUV) as opposed to the acute high doses common to laboratory experiments. Analysis of the cellular response to acute high-dose exposure has delineated the importance of direct DNA
