RAD51

MUT5, recombinase RAD51, L000001571, YER095W
Strand exchange protein; forms a helical filament with DNA that searches for homology; involved in the recombinational repair of double-strand breaks in DNA during vegetative growth and meiosis; homolog of Dmc1p and bacterial RecA protein

TOP1

MAK1, MAK17, DNA topoisomerase 1, L000002319, YOL006C
Topoisomerase I; nuclear enzyme that relieves torsional strain in DNA by cleaving and re-sealing the phosphodiester backbone; relaxes both positively and negatively supercoiled DNA; functions in replication, transcription, and recombination; role in processing ribonucleoside monophosphates in genomic DNA into irreversible single-strand breaks
Saccharomyces cerevisiae (S288c)

Synthetic Rescue

A genetic interaction is inferred when mutations or deletions of one gene rescues the lethality or growth defect of a strain mutated or deleted for another gene.

Topoisomerase I-mediated cleavage at unrepaired ribonucleotides generates DNA double-strand breaks.

Huang SN, Williams JS, Arana ME, Kunkel TA, Pommier Y

Ribonuclease activity of topoisomerase I (Top1) causes DNA nicks bearing 2',3'-cyclic phosphates at ribonucleotide sites. Here, we provide genetic and biochemical evidence that DNA double-strand breaks (DSBs) can be directly generated by Top1 at sites of genomic ribonucleotides. We show that RNase H2-deficient yeast cells displayed elevated frequency of Rad52 foci, inactivation of RNase H2 and RAD52 led to synthetic ... [more]
