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.


Genetic and physical interactions between Schizosaccharomyces pombe Mcl1 and Rad2, Dna2 and DNA polymerase alpha: evidence for a multifunctional role of Mcl1 in DNA replication and repair.

Schizosaccharomyces pombe rad2 is involved in Okazaki fragments processing during lagging-strand DNA replication. Previous studies identified several slr mutants that are co-lethal with rad2Delta and sensitive to methyl methanesulfonate as single mutants. One of these mutants, slr3-1, is characterized here. Complementation and sequence analyses show that slr3-1 (mcl1-101) is allelic to mcl1(+), which is required for chromosome replication, cohesion and ... [more]
