DIA2

YOR29-31, DNA-binding SCF ubiquitin ligase subunit DIA2, YOR080W
Origin-binding F-box protein; forms SCF ubiquitin ligase complex with Skp1p and Cdc53p; functions in ubiquitylation of silent chromatin structural protein Sir4p; required to target Cdc6p for destruction during G1 phase; required for deactivation of Rad53 checkpoint kinase, completion of DNA replication during recovery from DNA damage, assembly of RSC complex, RSC-mediated transcription regulation, and nucleosome positioning; involved in invasive and pseudohyphal growth
Saccharomyces cerevisiae (S288c)
PREY

TOF1

L000004244, YNL273W
Subunit of a replication-pausing checkpoint complex; Tof1p-Mrc1p-Csm3p acts at the stalled replication fork to promote sister chromatid cohesion after DNA damage, facilitating gap repair of damaged DNA; interacts with the MCM helicase; relocalizes to the cytosol in response to hypoxia
Saccharomyces cerevisiae (S288c)

Phenotypic Enhancement

A genetic interaction is inferred when mutation or overexpression of one gene results in enhancement of any phenotype (other than lethality/growth defect) associated with mutation or over expression of another gene.

Publication

The Intra-S phase checkpoint protein Tof1 collaborates with the helicase Rrm3 and the F-box protein Dia2 to maintain genome stability in Saccharomyces cerevisiae.

Bairwa NK, Mohanty BK, Stemenova R, Curcio MJ, Bastia D

The intra-S phase checkpoint protein complex Tof1/Csm3 of S. cerevisiae antagonizes Rrm3 helicase to modulate replication fork arrest not only at the replication termini of rDNA but also at strong nonhistone protein binding sites throughout the genome. We investigated whether these checkpoint proteins acted either antagonistically or synergistically with Rrm3 in mediating other important functions such as maintenance of genome ... [more]
