dual specificity mitogen activated protein kinase kinase 3
Dual specificity mitogen-activated protein kinase kinase 3
MAP kinase kinase 3

MAPK/ERK kinase 3
Mitogen activated protein kinase kinase 3
protein kinase, mitogen-activated, kinase 3
SAPK kinase 2
Stress activated protein kinase kinase 2
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.
Abundant expression is seen in the skeletal muscle. It is also widely expressed in other tissues.
Involvement in disease
Note=Defects in MAP2K3 may be involved in colon cancer.
Belongs to the protein kinase superfamily. STE Ser/Thr protein kinase family. MAP kinase kinase subfamily. Contains 1 protein kinase domain.
Autophosphorylated. Phosphorylation on Ser-218 and Thr-222 by MAP kinase kinase kinases regulates positively the kinase activity. Yersinia yopJ may acetylate Ser/Thr residues, preventing phosphorylation and activation, thus blocking the MAPK signaling pathway.
