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)

MEC1

ESR1, RAD31, SAD3, protein kinase MEC1, L000000586, S000029404, S000007656, YBR136W
Genome integrity checkpoint protein and PI kinase superfamily member; Mec1p and Dun1p function in same pathway to regulate dNTP pools and telomere length; signal transducer required for cell cycle arrest and transcriptional responses to damaged or unreplicated DNA; facilitates replication fork progression and regulates P-body formation under replication stress; promotes interhomolog recombination by phosphorylating Hop1p; associates with shortened, dysfunctional telomeres
Kinome Project (Sc)
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.

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]
