POL1

CDC17, CRT5, HPR3, DNA-directed DNA polymerase alpha catalytic subunit POL1, L000000257, YNL102W
Catalytic subunit of the DNA polymerase I alpha-primase complex; required for the initiation of DNA replication during mitotic DNA synthesis and premeiotic DNA synthesis
Saccharomyces cerevisiae (S288c)
PREY

MRC1

YCL060C, chromatin-modulating protein MRC1, YCL061C
S-phase checkpoint protein required for DNA replication; couples DNA helicase and DNA polymerase; interacts with and stabilizes Pol2p at stalled replication forks during stress, where it forms a pausing complex with Tof1p and is phosphorylated by Mec1p; with Hog1p defines a novel S-phase checkpoint that permits eukaryotic cells to prevent conflicts between DNA replication and transcription; protects uncapped telomeres; degradation via Dia2p help cells resume cell cycle
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.

Checkpoint kinase interaction with DNA polymerase alpha regulates replication progression during stress.

Hadjicharalambous A, Whale AJ, Can G, Skehel JM, Houseley JM, Zegerman P

Background: In eukaryotes, replication stress activates a checkpoint response, which facilitates genome duplication by stabilising the replisome. How the checkpoint kinases regulate the replisome remains poorly understood. The aim of this study is to identify new targets of checkpoint kinases within the replisome during replication stress. Methods: Here we use an unbiased biotin proximity-ligation approach in Saccharomyces cerevisiae to identify ... [more]

Throughput

  • Low Throughput

Ontology Terms

  • phenotype: resistance to chemicals (APO:0000087)

Additional Notes

  • genetic complex
  • mutation of all the Rad53 binding sites in replisome proteins (cdc45, mrc1 and pol1) led to increased sensitivity to HU
