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 ChEBI:CHEBI:83421, ChEBI:CHEBI:456216; EC=2.7.11.24;
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 Rhea:RHEA-COMP:11605, ChEBI:CHEBI:15378, ChEBI:CHEBI:30013,
CC ChEBI:CHEBI:30616, ChEBI:CHEBI:61977, ChEBI:CHEBI:456216;
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-126 and Tyr-128, 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}.
