REV5, DNA polymerase delta subunit POL32, L000004337, S000029416, L000001617, YJR043C
Third subunit of DNA polymerase delta; involved in chromosomal DNA replication; required for error-prone DNA synthesis in the presence of DNA damage and processivity; forms a complex with Rev3p, Rev7p and Pol31p; interacts with Hys2p, PCNA (Pol30p), and Pol1p

Phenotypic Suppression

A genetic interaction is inferred when mutation or over expression of one gene results in suppression of any phenotype (other than lethality/growth defect) associated with mutation or over expression of another gene.

RNA-DNA hybrids promote the expansion of Friedreich's ataxia (GAA)n repeats via break-induced replication.

Neil AJ, Liang MU, Khristich AN, Shah KA, Mirkin SM

Expansion of simple DNA repeats is responsible for numerous hereditary diseases in humans. The role of DNA replication, repair and transcription in the expansion process has been well documented. Here we analyzed, in a yeast experimental system, the role of RNA-DNA hybrids in genetic instability of long (GAA)n repeats, which cause Friedreich's ataxia. Knocking out both yeast RNase H enzymes, ... [more]

Mutations/deletions in separate genes, each of which alone causes a minimal phenotype, but when combined in the same cell results in a more severe fitness defect or lethality under a given condition. This term is reserved for high or low throughput studies with scores.
