Kinase: MAP2K3 mitogen-activated protein kinase kinase 3

Group: STE      Family: STE7      Subfamily: MEK3

Description: mitogen-activated protein kinase kinase 3

Gene Symbol: MAP2K3

Synonyms: MAPKK3, MEK3, MKK3, PRKMK3

UniprotKB/SwissProt: MP2K3_HUMAN (P46734)

Function: Dual specificity kinase. Is activated by cytokines and environmental stress in vivo. Catalyzes the concomitant phosphorylation of a threonine and a tyrosine residue in the MAP kinase p38.
