SSK1

mitogen-activated protein kinase kinase kinase SSK1, L000002084, YLR006C
Cytoplasmic phosphorelay intermediate osmosensor and regulator; part of a two-component signal transducer that mediates osmosensing via a phosphorelay mechanism; required for mitophagy; dephosphorylated form is degraded by the ubiquitin-proteasome system; potential Cdc28p substrate
Saccharomyces cerevisiae (S288c)
PREY

STE11

mitogen-activated protein kinase kinase kinase STE11, L000002118, YLR362W
Signal transducing MEK kinase; involved in pheromone response and pseudohyphal/invasive growth pathways where it phosphorylates Ste7p, and the high osmolarity response pathway, via phosphorylation of Pbs2p; regulated by Ste20p and Ste50p; protein abundance increases in response to DNA replication stress
Saccharomyces cerevisiae (S288c)

Synthetic Growth Defect

A genetic interaction is inferred when mutations in separate genes, each of which alone causes a minimal phenotype, result in a significant growth defect under a given condition when combined in the same cell.

Activation of the Hog1 MAPK by the Ssk2/Ssk22 MAP3Ks, in the absence of the osmosensors, is not sufficient to trigger osmostress adaptation in Saccharomyces cerevisiae.

Yeast cells respond to hyperosmotic stress by activating the high-osmolarity glycerol (HOG) pathway, which consists of two branches, Hkr1/Msb2-Sho1 and Sln1, which trigger phosphorylation and nuclear internalization of the Hog1 mitogen-activated protein kinase. In the nucleus, Hog1 regulates gene transcription and cell cycle progression, which allows the cell to respond and adapt to hyperosmotic conditions. This study demonstrates that the ... [more]
