Map kinase fus3 acts as a molecular switch
WebIn yeast STE20 is a component of the MAP kinase cascade required to transmit the pheromone signal from Gβγ subunits to downstream components . STE20 phosphorylates STE11 that phosphorylates STE7, thereby acting as a MAPKKK. STE7 in turn phosphorylates FUS3 and KSS1 MAP kinases, thus functioning as a MAPKK .

Did you know?
WebFUS3/KSS1 phosphorylation depends on two additional kinases, STE11 and STE7 (refs 2, 5,6). Genetic analyses predict an ordered pathway where STE11 acts before STE7 and FUS3/KSS1 (refs 2,7). Here we report that STE7 is a dual-specificity kinase that modifies FUS3 at the appropriate sites and stimulates its catalytic activity in vitro. WebFilamentous invasive growth of S. cerevisiae requires multiple elements of the mitogen-activated protein kinase (MAPK) signaling cascade that are also components of the mating pheromone response pathway. Here we show that, despite sharing several constituents, the two pathways use different MAP kinases. The Fus3 MAPK regulates mating, whereas …
