Protein

Mitogen-activated protein kinase HOG1

Gene
HOG1
Organism
Hortaea werneckii
Status
Reviewed - Annotation score: 4 out of 5 - 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.2 Publications

Catalytic activityi

ATP + a protein = ADP + a phosphoprotein.

Cofactori

Magnesium By similarity.

Enzyme regulationi

Activated by tyrosine and threonine phosphorylation By similarity.
