POL3

CDC2, HPR6, TEX1, DNA-directed DNA polymerase delta POL3, L000000242, YDL102W
Catalytic subunit of DNA polymerase delta; required for chromosomal DNA replication during mitosis and meiosis, intragenic recombination, repair of double strand DNA breaks, and DNA replication during nucleotide excision repair (NER)

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.

Drug-sensitive DNA Polymerase {delta} Reveals a Role for Mismatch Repair in Checkpoint Activation in Yeast.

Reha-Krantz LJ, Siddique MS, Murphy K, Tam A, O'Carroll M, Lou S, Schultz A, Boone C

We have used a novel method to activate the DNA damage S-phase checkpoint response in Saccharomyces cerevisiae - to slow lagging strand DNA replication by exposing cells expressing a drug-sensitive DNA polymerase δ (L612M-DNA pol δ) to the inhibitory drug phosphonoacetic acid (PAA). PAA-treated pol3-L612M cells arrest as large budded cells with a single nucleus in the bud neck. This ... [more]
