ORC6

origin recognition complex subunit 6, L000001306, YHR118C
Subunit of the origin recognition complex (ORC); ORC directs DNA replication by binding to replication origins and is also involved in transcriptional silencing; phosphorylated by Cdc28p; mutation in the human Orc6p is linked to Meier-Gorlin syndrome
Saccharomyces cerevisiae (S288c)
PREY

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
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.

Disruption of mechanisms that prevent rereplication triggers a DNA damage response.

Archambault V, Ikui AE, Drapkin BJ, Cross FR

Eukaryotes replicate DNA once and only once per cell cycle due to multiple, partially overlapping mechanisms efficiently preventing reinitiation. The consequences of reinitiation are unknown. Here we show that the induction of rereplication by mutations in components of the prereplicative complex (origin recognition complex [ORC], Cdc6, and minichromosome maintenance proteins) causes a cell cycle arrest with activated Rad53, a large-budded ...
