The high-osmolarity glycerol (HOG) and cell wall integrity (CWI) signalling pathways interplay: a yeast dialogue between MAPK routes.
Two mitogen-activated protein kinase (MAPK) pathways, viz. the high-osmolarity glycerol (HOG) and the cell wall integrity (CWI) pathways, regulate stress responses in the yeast Saccharomyces cerevisiae. Whereas the former is mainly involved in adaptation of yeast cells to hyperosmotic stress, the latter is activated under conditions leading to cell wall instability. Although MAPK signalling specificity can be conceived as requiring insulation of the different pathways, it is also becoming clear that the two pathways do not compete with each other but can be positively coordinated to regulate many stress responses. This review highlights our current knowledge about the collaboration between these two MAPK pathways to counteract different kinds of environmental stress.
