Mitogen-activated protein kinase HOG1

Gene

HOG1

Organism
Gibberella intermedia (Bulb rot disease fungus) (Fusarium proliferatum)
Status
Reviewed-Annotation score: -Protein inferred from homologyi

Functioni

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 (By similarity).By similarity

Catalytic activityi

ATP + a protein = ADP + a phosphoprotein.

Cofactori

Mg2+By similarity

Enzyme regulationi

Activated by tyrosine and threonine phosphorylation.By similarity
