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

Synthetic Growth Defect

A genetic interaction is inferred when mutations in separate genes, each of which alone causes a minimal phenotype, result in a significant growth defect under a given condition when combined in the same cell.

DNA topoisomerase I (Top1p) catalyzes changes in DNA topology via the formation of an enzyme-DNA covalent complex that is reversibly stabilized by the antitumor drug, camptothecin (CPT). During S-phase, collisions with replication forks convert these complexes into cytotoxic DNA lesions that trigger cell cycle arrest and cell death. To investigate cellular responses to CPT-induced DNA damage, a yeast genetic screen ... [more]
