POL32

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
Saccharomyces cerevisiae (S288c)

MCM10

DNA43, L000000512, YIL150C
Essential chromatin-associated protein; involved in the initiation of DNA replication; required for the association of the MCM2-7 complex with replication origins; required to stabilize the catalytic subunit of DNA polymerase-alpha
Saccharomyces cerevisiae (S288c)

Dosage Growth Defect

A genetic interaction is inferred when over expression or increased dosage of one gene causes a growth defect in a strain that is mutated or deleted for another gene.

Stabilization of expandable DNA repeats by the replication factor Mcm10 promotes cell viability.

Trinucleotide repeats, including Friedreich's ataxia (GAA)n repeats, become pathogenic upon expansions during DNA replication and repair. Here, we show that deficiency of the essential replisome component Mcm10 dramatically elevates (GAA)n repeat instability in a budding yeast model by loss of proper CMG helicase interaction. Supporting this conclusion, live-cell microscopy experiments reveal increased replication fork stalling at the repeat in mcm10-1 ... [more]
