PTP3
tyrosine protein phosphatase PTP3, L000003996, YER075C
Phosphotyrosine-specific protein phosphatase; involved in the inactivation of mitogen-activated protein kinase (MAPK) during osmolarity sensing; dephosporylates Hog1p MAPK and regulates its localization; localized to the cytoplasm

HKR1
L000000788, YDR420W
Mucin family member that functions as an osmosensor in the HOG pathway; functions in the Sho1p-mediated HOG pathway with Msb2p; proposed to be a negative regulator of filamentous growth; mutant displays defects in beta-1,3 glucan synthesis and bud site selection

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.

Dynamic control of yeast MAP kinase network by induced association and dissociation between the Ste50 scaffold and the Opy2 membrane anchor.
Membrane localization of the Ste11 MAPKKK is essential for activation of both the filamentous growth/invasive growth (FG/IG) MAP kinase (MAPK) pathway and the SHO1 branch of the osmoregulatory HOG MAPK pathway, and is mediated by binding of the Ste50 scaffold protein to the Opy2 membrane anchor. We found that Opy2 has two major (CR-A and CR-B), and one minor (CR-D), ... [more]
