General annotation (Comments)

Function	Mitogen-activated protein kinase involved in a signal transduction pathway that is activated by changes in the osmolarity of the extracellular environment. Controls osmotic regulation of transcription of target genes. Ref.2 Ref.4
Catalytic activity	ATP + a protein = ADP + a phosphoprotein.
Cofactor	Magnesium By similarity.
Enzyme regulation	Activated by tyrosine and threonine phosphorylation By similarity.
Subcellular location	Cytoplasm By similarity. Nucleus By similarity.
Domain	The TXY motif contains the threonine and tyrosine residues whose phosphorylation activates the MAP kinases.
Post-translational modification	Dually phosphorylated on Thr-171 and Tyr-173, which activates the enzyme By similarity. Phosphorylated by pbsB in response to osmotic and oxidative stresses. Ref.2 Ref.4
Sequence similarities	Belongs to the protein kinase superfamily. Ser/Thr protein kinase family. MAP kinase subfamily. HOG1 sub-subfamily. Contains 1 protein kinase domain.
