Cleavage-defective Topoisomerase I mutants sharply increase G-quadruplex-associated genomic instability

Topoisomerase 1 (Top1) removes transcription-associated helical stress to sup-press G4-formation and its induced recombination at genomic loci containing guanine-run containing sequences. Interestingly, Top1 binds tightly to G4 struc-tures, and its inhibition or depletion can cause elevated instabil...
