ARP2

ACT2, actin-related protein 2, L000000026, YDL029W
Essential component of the Arp2/3 complex; Arp2/3 is a highly conserved actin nucleation center required for the motility and integrity of actin patches; involved in endocytosis and membrane growth and polarity; required for efficient Golgi-to-ER trafficking in COPI mutants
Saccharomyces cerevisiae (S288c)
PREY

WHI3

mRNA-binding protein WHI3, L000002486, YNL197C
RNA binding protein that sequesters CLN3 mRNA in cytoplasmic foci; regulates genes involved in the cell cycle, sister chromatid cohesion, and stress response; acts as a cytoplasmic retention factor for Cdc28p and associated cyclins; regulates cell fate and dose-dependently regulates the critical cell size required for passage through Start; Tpk1p (PKA) mediated phosphorylation (S568) inhibits Whi3p function, decreasing its interaction with CLN3 mRNA; regulates ploidy
Saccharomyces cerevisiae (S288c)

Synthetic Rescue

A genetic interaction is inferred when mutations or deletions of one gene rescues the lethality or growth defect of a strain mutated or deleted for another gene.

Whi3 regulates morphogenesis in budding yeast by enhancing Cdk functions in apical growth.

Colomina N, Ferrezuelo F, Verges E, Aldea M, Gari E

The Whi3 protein is associated with the endoplasmic reticulum, interacts with Cdc28, the budding-yeast Cdk, binds the mRNA of cyclin CLN3 and prevents accumulation of the Cdc28-Cln3 in the nucleus until late G(1). Besides its function as a cell size regulator, Whi3 is strictly required for filamentous growth. Here we show that emerging buds in Whi3-deficient cells are considerably rounder ... [more]

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.
