DNA–protein crosslinks and their resolution

P Weickert, J Stingele - Annual Review of Biochemistry, 2022 - annualreviews.org
Covalent DNA–protein crosslinks (DPCs) are pervasive DNA lesions that interfere with
essential chromatin processes such as transcription or replication. This review strives to …

TP53-dependent toxicity of CRISPR/Cas9 cuts is differential across genomic loci and can confound genetic screening

MM Álvarez, J Biayna, F Supek - Nature communications, 2022 - nature.com
CRISPR/Cas9 gene editing can inactivate genes in a precise manner. This process involves
DNA double-strand breaks (DSB), which may incur a loss of cell fitness. We hypothesize that …

RAD51 protects abasic sites to prevent replication fork breakage

YW Hanthi, MA Ramirez-Otero, R Appleby, A De Antoni… - Molecular cell, 2024 - cell.com
Abasic sites are DNA lesions repaired by base excision repair. Cleavage of unrepaired
abasic sites in single-stranded DNA (ssDNA) can lead to chromosomal breakage during …
