Outline of Final Research Achievements

The mucin-like membrane protein Msb2, the membrane anchor protein Opy2, and the adaptor protein Ste50 play important roles in activation of the HOG MAPK pathway and the FG MAPK pathway. When a cytoplasmic B site of Opy2 is phosphorylated by casein kinases Yck1/Yck2 under nutrient-rich conditions, it binds Ste50 and only leads to activation of the HOG pathway. Mutants were isolated that have mutations in genes encoding molecules, that negatively regulate phosphorylation of the B site. Extracellular binding between Mab2 and Opy2 was changed by osmostress.
