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)


RTT108, SLM6, L000003933, YPR164W
Subunit of E3 ubiquitin ligase complex involved in replication repair; stabilizes protein components of the replication fork such as the fork-pausing complex and leading strand polymerase, preventing fork collapse and promoting efficient recovery during replication stress; regulates Ty1 transposition; involved with Rtt101p in nonfunctional rRNA decay

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 ...
