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

DIF1

YLR437C
Protein that regulates nuclear localization of Rnr2p and Rnr4p; phosphorylated by Dun1p in response to DNA damage and degraded; N-terminal half shows similarity to S. pombe Spd1 protein; DIF1 has a paralog, SML1, that arose from the whole genome duplication

Synthetic Rescue

A genetic interaction is inferred when mutations or deletions of one gene rescues the lethality or growth defect of a strain mutated or deleted for another gene.

Publication

Dif1 controls subcellular localization of ribonucleotide reductase by mediating nuclear import of the R2 subunit.

Wu X, Huang M

Fidelity in DNA replication and repair requires adequate and balanced deoxyribonucleotide pools that are maintained primarily by regulation of ribonucleotide reductase (RNR). RNR is controlled via transcription, protein inhibitor association, and subcellular localization of its two subunits, R1 and R2. Saccharomyces cerevisiae Sml1 binds R1 and inhibits its activity, while Schizosaccharomyces pombe Spd1 impedes RNR holoenzyme formation by sequestering R2 ... [more]
