Recombinant Human Dual specificity mitogen-activated protein kinase kinase 3 (MAP2K3)

Uniprot Id

P46734

Target Species

Human

Target Name

MAP2K3

Target Full Name

Dual specificity mitogen-activated protein kinase kinase 3

Target 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. Part of a signaling cascade that begins with the activation of the adrenergic receptor ADRA1B and leads to the activation of MAPK14.

Target Involvement

Defects in MAP2K3 may be involved in colon cancer.

Target Protein Families

Protein kinase superfamily, STE Ser/Thr protein kinase family, MAP kinase kinase subfamily

Target Tissue Specificity

Abundant expression is seen in the skeletal muscle. It is also widely expressed in other tissues.

Target Research Area

Cancer

Target Background

The protein encoded by this gene is a dual specificity protein kinase that belongs to the MAP kinase kinase family. This kinase is activated by mitogenic and environmental stress, and participates in the MAP kinase-mediated signaling cascade. It phosphorylates and thus activates MAPK14/p38-MAPK. This kinase can be activated by insulin, and is necessary for the expression of glucose transporter. Expression of RAS oncogene is found to result in the accumulation of the active form of this kinase, which thus leads to the constitutive activation of MAPK14, and confers oncogenic transformation of primary cells. The inhibition of this kinase is involved in the pathogenesis of Yersina pseudotuberculosis. Multiple alternatively spliced transcript variants that encode distinct isoforms have been reported for this gene.
