CC   -!- FUNCTION: Plasma membrane osmosensor that activates the high osmolarity
CC       glycerol (HOG) MAPK signaling pathway in response to high osmolarity.
CC       Detects changes in external osmolarity and activates PBS2 through the
CC       stimulation of STE11 and targets PBS2 to the plasma membrane. PBS2
CC       activation leads to changes in glycerol production that helps to
CC       balance the intracellular and external osmotic pressures. Activates
CC       also HOG1 in response to heat stress and mediates resistance to
CC       oxidative stress. Involved in the regulation of the mating pathway. May
CC       be a receptor that feeds into the pseudohyphal growth pathway (By
CC       similarity). {ECO:0000250}.
CC   -!- SUBUNIT: Forms homooligomers (By similarity). Interacts (via the SH3
CC       domain) with PBS2. Interacts with FUS1, STE11, STE50 and RNA polymerase
CC       II (By similarity). {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000250}; Multi-pass membrane
CC       protein {ECO:0000250}. Bud {ECO:0000250}. Bud neck {ECO:0000250}. Cell
CC       projection {ECO:0000250}. Note=Localizes at the tip of the mating
CC       projection during conjugation. {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the SHO1 family. {ECO:0000305}.
