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)

CST21, DNA-directed RNA polymerase I subunit RPA34, A34.5, L000004132, L000003000, S000029123, YJL148W
RNA polymerase I subunit A34.5; essential for nucleolar assembly and for high polymerase loading rate; nucleolar localization depends on Rpa49p
Saccharomyces cerevisiae (S288c)

Synthetic Lethality

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

A34.5, a nonessential component of yeast RNA polymerase I, cooperates with subunit A14 and DNA topoisomerase I to produce a functional rRNA synthesis machine.

Gadal O, Mariotte-Labarre S, Chedin S, Quemeneur E, Carles C, Sentenac A, Thuriaux P

A34.5, a phosphoprotein copurifying with RNA polymerase I (Pol I), lacks homology to any component of the Pol II or Pol III transcription complexes. Cells devoid of A34.5 hardly affect growth and rRNA synthesis and generate a catalytically active but structurally modified enzyme also lacking subunit A49 upon in vitro purification. Other Pol I-specific subunits (A49, A14, and A12.2) are ... [more]
