Mitogen-activated protein kinase kinase kinase 2

Gene

Map3k2

Organism
Mus musculus (Mouse)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Component of a protein kinase signal transduction cascade. Regulates the JNK and ERK5 pathways by phosphorylating and activating MAP2K5 and MAP2K7. Plays a role in caveolae kiss-and-run dynamics (By similarity).By similarity1 Publication

Catalytic activityi

ATP + a protein = ADP + a phosphoprotein.

Cofactori

Enzyme regulationi

Activated by phosphorylation on Thr-524 (By similarity). Interacts with PKN2; the interaction activates PKN2 kinase activity in a MAP3K2-independent kinase activity.By similarity
