Research Abstract

When exposed to environmental hyperosmolarity, the budding yeast Saccharomyces cerevisiae activates the Hog1 MAP kinase signal pathway, which governs an array of adaptive responses. In this project, we investigated how the activity of the Hog1 MAPK pathway is regulated by the two newly discovered osmosensors Hkr1 and Msb2. We also investigated the roles of the membrane anchor protein Opy2, membrane protein Sho1, and the adaptor protein Ste50 in dynamic regulation of the Hog1 MAPK pathway.
