FAR1

cyclin-dependent protein serine/threonine kinase inhibiting protein FAR1, L000000600, YJL157C
CDK inhibitor and nuclear anchor; during the cell cycle Far1p sequesters the GEF Cdc24p in the nucleus; phosphorylation by Cdc28p-Cln results in SCFCdc4 complex-mediated ubiquitin-dependent degradation, releasing Cdc24p for export and activation of GTPase Cdc42p; in response to pheromone, phosphorylation of Far1p by MAPK Fus3p results in association with, and inhibition of Cdc28p-Cln, as well as Msn5p mediated nuclear export of Far1p-Cdc24p, targeting Cdc24p to polarity sites

STE5

HMD3, NUL3, L000002115, YDR103W
Pheromone-responsive MAPK scaffold protein; couples activation of the G-protein-coupled pheromone receptor to MAPK activation; intramolecular interaction of PH and VWA domains blocks activation of assembled signaling cascade components (Ste11p, Ste7p and Fus3p) under basal conditions; Gbeta-gamma (Ste4p-Ste18p)-dependent docking at the plasma membrane and binding of PI(4,5)P2 by the PH domain relieves autoinhibition, resulting in pheromone-dependent pathway activation

Dosage Rescue

A genetic interaction is inferred when over expression or increased dosage of one gene rescues the lethality or growth defect of a strain that is mutated or deleted for another gene.

Cloning of Saccharomyces cerevisiae STE5 as a suppressor of a Ste20 protein kinase mutant: structural and functional similarity of Ste5 to Far1.

Leberer E, Dignard D, Harcus D, Hougan L, Whiteway M, Thomas DY

The beta and gamma subunits of the mating response G-protein in the yeast Saccharomyces cerevisiae have been shown to transmit the mating pheromone signal to downstream components of the pheromone response pathway. A protein kinase homologue encoded by the STE20 gene has recently been identified as a potential G beta gamma target. We have searched multicopy plasmid genomic DNA libraries ... [more]
