CC   -!- FUNCTION: Mitogen-activated protein kinase involved in a signal
CC       transduction pathway that is activated by changes in the osmolarity of
CC       the extracellular environment. Controls osmotic regulation of
CC       transcription of target genes (By similarity). {ECO:0000250}.
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         EC=2.7.11.24;
CC   -!- COFACTOR:
CC       Name=Mg(2+); Xref=ChEBI:CHEBI:18420; Evidence={ECO:0000250};
CC   -!- ACTIVITY REGULATION: Activated by tyrosine and threonine
CC       phosphorylation. {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250}. Nucleus {ECO:0000250}.
CC   -!- DOMAIN: The TXY motif contains the threonine and tyrosine residues
CC       whose phosphorylation activates the MAP kinases.
CC   -!- PTM: Dually phosphorylated on Thr-144 and Tyr-146, which activates the
CC       enzyme. {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the protein kinase superfamily. Ser/Thr protein
CC       kinase family. MAP kinase subfamily. HOG1 sub-subfamily.
CC       {ECO:0000255|PROSITE-ProRule:PRU00159}.
