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

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.

Ubc9- and mms21-mediated sumoylation counteracts recombinogenic events at damaged replication forks.

The Ubc9 SUMO-conjugating enzyme and the Siz1 SUMO ligase sumoylate several repair and recombination proteins, including PCNA. Sumoylated PCNA binds Srs2, a helicase counteracting certain recombination events. Here we show that ubc9 mutants depend on checkpoint, recombination, and replication genes for growth. ubc9 cells maintain stalled-fork stability but exhibit a Rad51-dependent accumulation of cruciform structures during replication of damaged templates. ...
