PLC1
phosphatidylinositol phospholipase C, L000001448, YPL268W
Phospholipase C; hydrolyzes phosphatidylinositol 4,5-biphosphate (PIP2) to generate the signaling molecules inositol 1,4,5-triphosphate (IP3) and 1,2-diacylglycerol (DAG); involved in regulating many cellular processes; Plc1p and inositol polyphosphates are required for acetyl-CoA homeostasis which regulates global histone acetylation

MGO1, SCF ubiquitin ligase subunit SKP1, CBF3D, L000001910, YDR328C
Evolutionarily conserved kinetochore protein; part of multiple protein complexes, including the SCF ubiquitin ligase complex, the CBF3 complex that binds centromeric DNA, and the RAVE complex that regulates assembly of the V-ATPase; protein abundance increases in response to DNA replication stress

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.

Genetic evidence for a role of phospholipase C at the budding yeast kinetochore.
Chromosome segregation during mitosis requires kinetochores, specialized organelles that mediate chromosome attachment to spindle microtubules. We have shown previously that in budding yeast, Plc1p (phosphoinositide-specific phospholipase C) localizes to centromeric loci, associates with the kinetochore proteins Ndc10p and Cep3p, and affects the function of kinetochores. Deletion of PLC1 results in nocodazole sensitivity, mitotic delay, and a higher frequency of chromosome ... [more]
