SIT4
PPH1, type 2A-related serine/threonine-protein phosphatase SIT4, L000001901, YDL047W
Type 2A-related serine-threonine phosphatase; functions in the G1/S transition of the mitotic cycle; regulator of COPII coat dephosphorylation; required for ER to Golgi traffic; interacts with Hrr25p kinase; cytoplasmic and nuclear protein that modulates functions mediated by Pkc1p including cell wall and actin cytoskeleton organization; similar to human PP6

PTC2
type 2C protein phosphatase PTC2, L000003403, YER089C
Type 2C protein phosphatase (PP2C); dephosphorylates Hog1p to limit maximal osmostress induced kinase activity; dephosphorylates Ire1p to downregulate the unfolded protein response; dephosphorylates Cdc28p; inactivates the DNA damage checkpoint; PTC2 has a paralog, PTC3, that arose from the whole genome duplication

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.

Identification of multicopy suppressors of cell cycle arrest at the G1-S transition in Saccharomyces cerevisiae.
Inactivation of HAL3 in the absence of SIT4 function leads to cell cycle arrest at the G(1)-S transition. To identify genes potentially involved in the control of this phase of the cell cycle, a screening for multicopy suppressors of a conditional sit4 hal3 mutant (strain JC002) has been developed. The screening yielded several genes known to perform key roles in ... [more]
