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.

Apn2 resolves blocked 3' ends and suppresses Top1-induced mutagenesis at genomic rNMP sites.

Ribonucleoside monophosphates (rNMPs) mis-incorporated during DNA replication are removed by RNase H2-dependent excision repair or by topoisomerase I (Top1)-catalyzed cleavage. The cleavage of rNMPs by Top1 produces 3' ends harboring terminal adducts, such as 2',3'-cyclic phosphate or Top1 cleavage complex (Top1cc), and leads to frequent mutagenesis and DNA damage checkpoint induction. We surveyed a range of candidate enzymes from Saccharomyces ... [more]
