CC -!- FUNCTION: MAP4K component of the MAPK pathway required for the mating
CC pheromone response, haploid invasive growth and diploid pseudohyphal
CC development. Links the pheromone response G-protein beta gamma subunits
CC to downstream signaling components. Needed for mating in haploid cells,
CC induction of a mating-specific gene FUS1, induction of mating-specific
CC morphologies, and pheromone-induced proliferation arrest. Required for
CC the regulation of the actin polarization and bud emergence during cell
CC cycle in G1. Involved in the high osmolarity glycerol (HOG) response.
CC Phosphorylates 'Thr-307' and 'Ser-302' or 'Ser-306' of STE11 and 'Ser-
CC 357' of MYO3. Phosphorylates histone H2B to form H2BS10ph during
CC meiosis and H(2)O(2)-induced apoptosis. Its interaction with CDC42 is
CC required for both invasive growth and the formation of pseudohyphae.
CC Its interaction with STE4 is required for the pheromone signaling.
