Enzyme ClassNot Available
Biological Properties
General Functionprotein phosphorylation
Specific FunctionTogether with closely related KSS1, FUS3 is the final kinase in the signal transduction cascade regulating activation/repression of the mating and filamentation pathways, induced by pheromone and nitrogen/carbon limitation, respectively. Phosphorylated FUS3 activates the mating but suppresses the filamentation pathway, whereas activated KSS1 activates both pathways. Pheromone-activated FUS3 functions by inhibiting the binding of the transcriptional activator STE12 to filamentation specific genes while inducing its binding to and activity at mating specific genes. Non-activated FUS3 has a repressive effect on STE12 transcriptional activity. KSS1 can partially compensate for the lack of FUS3 but mating efficiency is reduced and the filamentation program is partially activated upon pheromone signaling. FUS3 phosphorylates STE7, STE5, FAR1, DIG1, DIG2 and STE12.
