CC -!- FUNCTION: Cell wall stress sensor. Involved in activation of a response
CC that includes both stress-related increased chitin synthesis and the
CC MPK1 mitogen-activated protein kinase cell integrity pathway. High-copy
CC activator of the SKN7 transcription factor. Required during induction
CC of MPK1 tyrosine phosphorylation under a variety of stress conditions.
CC Required for PKC pathway activation under low pH conditions. Required
CC for cell integrity signaling during pheromone-induced morphogenesis.
CC Activates ROM1 or ROM2 catalyzed guanine nucleotide exchange toward
CC RHO1 in cell wall integrity signaling. {ECO:0000269|PubMed:10330137,
