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.

Species
Homo Sapiens (Human)
Specificity
The antibody detects endogenous levels of MAP2K3 only when phosphorylated at threonine 222.
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.
Pathway
MAPK signaling pathway TNF signaling pathway Cellular senescence Fc epsilon RI signaling pathway Toll-like receptor signaling pathway Rap1 signaling pathway
Protein Families
Protein kinase superfamily, STE Ser/Thr protein kinase family, MAP kinase kinase subfamily
Tissue Specificity
Abundant expression is seen in the skeletal muscle. It is also widely expressed in other tissues.

Purification
Antibodies were produced by immunizing rabbits with synthetic phosphopeptide and KLH conjugates. Antibodies were purified by affinity-chromatography using epitope-specific phosphopeptide. Non-phospho specific antibodies were removed by chromatogramphy usi
