"WebThe MAPK module is a three-tiered phosphorelay system composed of Ste11 (MAPKKK), Ste7 (MAPKK) and Fus3 (MAPK). Upon signal activation, the phosphoactivated Fus3 releases the downstream transcription factor Ste12 from inhibition by Dig1/Dig2, which induces the expression of several mating-specific genes (Bardwell et al., 1994).

Web18. dec 2007. · The FCS curves for Ste7, Ste11, Fus3, and Kss1 revealed slower transit times (τ D), suggesting these proteins are in complexes that are on average larger than Ste5 (Fig. 2A, SI Table 1). Upon pheromone stimulation, τ D for Ste5, Fus3, Kss1, Ste7, and Ste11 further increased , suggesting an increase in size of their associated complexes. Webkinases may activate one MAP kinase isoform through the activation of Raf and MAP kinase kinase, but this same isoform may also be activated by a G-protein/pro-tein kinase C cascade that acts through MAP kinase ki nase kinase (Lange-Carter et al. 1993).
