GRR1
CAT80, COT2, SDC1, SSU2, SCF ubiquitin ligase complex subunit GRR1, L000000730, YJR090C
F-box protein component of an SCF ubiquitin-ligase complex; modular substrate specificity factor which associates with core SCF (Cdc53p, Skp1p and Hrt1p/Rbx1p) to form the SCF(Grr1) complex; SCF(Grr1) acts as a ubiquitin-protein ligase directing ubiquitination of substrates such as: Gic2p, Mks1p, Mth1p, Cln1p, Cln2p and Cln3p; involved in carbon catabolite repression, glucose-dependent divalent cation transport, glucose transport, morphogenesis, and sulfite detoxification

SNF3
L000001946, YDL194W
Plasma membrane low glucose sensor, regulates glucose transport; contains 12 predicted transmembrane segments and a long C-terminal tail required for induction of hexose transporters; also senses fructose and mannose; SNF3 has a paralog, RGT2, that arose from the whole genome duplication

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.

Altered regulatory responses to glucose are associated with a glucose transport defect in grr1 mutants of Saccharomyces cerevisiae.
The GRR1 gene of Saccharomyces cerevisiae affects glucose repression, cell morphology, divalent cation transport and other processes. We present a kinetic analysis showing that the grr1 mutant is also defective in high affinity glucose transport. In combination with a mutation in SNF3, a member of the glucose transporter gene family, grr1 strikingly impairs growth on glucose. These findings suggest that ... [more]
