Protein

Mitogen-activated protein kinase 4

Gene
Mapk4, Prkm4
Organism
Rattus norvegicus (Rat)
Status
Reviewed - Annotation score: 4 out of 5 - Experimental evidence at transcript leveli

Functioni

Atypical MAPK protein. Phosphorylates microtubule-associated protein 2 (MAP2) and MAPKAPK5. The precise role of the complex formed with MAPKAPK5 is still unclear, but the complex follows a complex set of phosphorylation events: upon interaction with atypical MAPKAPK5, ERK4/MAPK4 is phosphorylated and then mediates phosphorylation and activation of MAPKAPK5, which in turn phosphorylates ERK4/MAPK4. May promote entry in the cell cycle By similarity.

Catalytic activityi

ATP + a protein = ADP + a phosphoprotein.

Cofactori

Magnesium By similarity.

Enzyme regulationi

Activated by phosphorylation in the activation loop By similarity.
