SWI4

ART1, SBF complex DNA-binding subunit SWI4, L000000124, L000002252, YER111C
DNA binding component of the SBF complex (Swi4p-Swi6p); a transcriptional activator that in concert with MBF (Mbp1-Swi6p) regulates late G1-specific transcription of targets including cyclins and genes required for DNA synthesis and repair; Slt2p-independent regulator of cold growth; acetylation at two sites, K1016 and K1066, regulates interaction with Swi6p
Saccharomyces cerevisiae (S288c)
PREY

DBF4

DNA52, LSD7, protein serine/threonine kinase activating protein DBF4, L000000488, S000029149, L000000513, YDR052C
Regulatory subunit of Cdc7p-Dbf4p kinase complex; required for Cdc7p kinase activity and initiation of DNA replication; phosphorylates the Mcm2-7 family of proteins; cell cycle regulated; relative distribution to the nucleus increases upon DNA replication stress
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 inhibition of origin firing prevents inappropriate replication outside of S-phase.

Johnson MC, Can G, Santos MM, Alexander D, Zegerman P

Checkpoints maintain the order of cell cycle events during DNA damage or incomplete replication. How the checkpoint response is tailored to different phases of the cell cycle remains poorly understood. The S-phase checkpoint for example results in the slowing of replication, which in budding yeast occurs by Rad53-dependent inhibition of the initiation factors Sld3 and Dbf4. Despite this, we show ... [more]

Throughput

  • Low Throughput

Additional Notes

  • genetic complex
  • we observe much greater firing of early origins in the swi4-t/sld3-A/dbf4-A strain compared to swi4-t alone

Mutations/deletions in separate genes, each of which alone causes a minimal phenotype, but when combined in the same cell results in a more severe fitness defect or lethality under a given condition. This term is reserved for high or low throughput studies with scores.
