This MAP2K4 (MEK4) recombinant human protein (full length) was expressed in insect cells. MAP2K4 (MEK4) serine/threonine kinase (mitogen-activated protein kinase kinase 4) MEK4 or MKK4 is a dual specificity kinase of the STE7 family that phosphorylates and activates JNK1 and -2 as well as p38. MAP2K4 preferentially phosphorylates the tyrosine residue of JNKs. MAP2K4 mediates a variety of physiological and pathophysiological processes such as responses to cellular stresses and inflammatory cytokines. MAP2K4 is important for carcinogenesis; a loss-off-function mutation in MAP2K4 was found in lung and pancreatic tumors. Conversely, a pro-oncogenic role was also found for MAP2K4. MAP2K4 (MEK4) recombinant human protein is also available in our SelectScreen™ Kinase Profiling Service.
