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)
PREY

WHI4

L000004493, YDL224C
Putative RNA binding protein; regulates the cell size requirement for passage through Start and commitment to cell division; WHI4 has a paralog, WHI3, that arose from the whole genome duplication

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.

Isolation and characterization of WHI3, a size-control gene of Saccharomyces cerevisiae.

Nash RS, Volpe T, Futcher B

WHI3 is a gene affecting size control and cell cycle in the yeast Saccharomyces cerevisiae. The whi3 mutant has small cells, while extra doses of WHI3 produce large cells, and a large excess of WHI3 produces a lethal arrest in G1 phase. WHI3 seems to be a dose-dependent inhibitor of Start. Whi3 and its partially redundant homolog Whi4 have an ... [more]
