CC -!- FUNCTION: Mitogen-activated protein kinase (MAPK) that plays a role in
CC conidiation and regulation of secondary metabolite biosynthesis
CC (PubMed:30914505). Acts as a repressor of dihydroxynaphthalene (DHN)-
CC melanin production (PubMed:30914505). {ECO:0000269|PubMed:30914505}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=ATP + L-seryl-[protein] = ADP + H(+) + O-phospho-L-seryl-
CC [protein]; Xref=Rhea:RHEA:17989, Rhea:RHEA-COMP:9863, Rhea:RHEA-

CC -!- CATALYTIC ACTIVITY:
CC Reaction=ATP + L-threonyl-[protein] = ADP + H(+) + O-phospho-L-
CC threonyl-[protein]; Xref=Rhea:RHEA:46608, Rhea:RHEA-COMP:11060,

CC PhysiologicalDirection=left-to-right; Xref=Rhea:RHEA:46609;
CC Evidence={ECO:0000305|PubMed:30914505};
CC -!- COFACTOR:
CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC Evidence={ECO:0000255|RuleBase:RU361165};
CC -!- ACTIVITY REGULATION: Activated by threonine and tyrosine
CC phosphorylation. {ECO:0000255|RuleBase:RU361165}.
CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000269|PubMed:30914505}.
CC Note=Translocates into the nucleus upon exposure to caspofungin stress,
CC and this is dependent on the cross-talk interaction with mpkA.
CC {ECO:0000269|PubMed:30914505}.
CC -!- DISRUPTION PHENOTYPE: Leads to a strong increase of
CC dihydroxynaphthalene (DHN)-melanin production (PubMed:30914505).
CC Results in about 3-fold less glucosamine and a lower level of alpha-
CC linked mannose within the cell wall (PubMed:30914505). Does not affect
CC virulence (PubMed:30914505). {ECO:0000269|PubMed:30914505}.
CC -!- SIMILARITY: Belongs to the protein kinase superfamily. Ser/Thr protein
CC kinase family. MAP kinase subfamily. {ECO:0000305}.
