|Storage||Maintain refrigerated at 2-8°C for up to 6 months. For long term storage store at -20°C in small aliquots to prevent freeze-thaw cycles.|
|Precautions||MKK3 Antibody (N-term) is for research use only and not for use in diagnostic or therapeutic procedures.|
|Synonyms||MEK3, MKK3, PRKMK3, SKK2|
|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.|
|Tissue Location||Abundant expression is seen in the skeletal muscle. It is also widely expressed in other tissues|

Mitogen-acitvated protein kinase kinase 3 (MKK3) belongs to the serine/threonine protein kinase family and the MAPK kinase subfamily (MAP2K, MKK or MEKs). MAPKs require dual phosphorylation on threonine and tyrosine residues, an activation step carried out by MAPK kinase (1-2). MKK3, closely related to MKK6, efficiently phosphorylates and activates p38 MAP kinase in response to inflammatory cytokines and environmental stress but not JNK or ERK (3). MKK3 is activated by mitogenic and environ-mental stress stimulus as well as by insulin. MKK3 is necessary for the expression of glucose transporter and participates in the MAP kinase- mediated signaling cascade (4).
