Summary: Enables MAP kinase activity. Involved in several processes, including invasive growth in response to glucose limitation; pheromone response MAPK cascade; and positive regulation of protein export from nucleus. Located in cytoplasm; mating projection tip; and nucleus. Human ortholog(s) of this gene implicated in Noonan syndrome 13; Parkinson's disease; carcinoma (multiple); melanoma; and pulmonary hypertension. Orthologous to several human genes including MAPK1 (mitogen-activated protein kinase 1). [provided by Alliance of Genome Resources, Nov 2024]

Title: Negative feedback that improves information transmission in yeast signalling.
Fus3 induces polarized growth in G1 phase cells by down-regulating Ste5 recruitment and by inhibiting Cln/Cdc28 kinase, which prevents basal recruitment of Ste5, Cdc42-mediated asymmetry, and mating morphogenesis.
