MAP2K4 is a dual specificity protein kinase that belongs to the Ser/Thr protein kinase family. This kinase is a direct activator of MAP kinases in response to various environmental stresses or mitogenic stimuli. It has been shown to activate MAPK8/JNK1, MAPK9/JNK2, and MAPK14/p38, but not MAPK1/ERK2 or MAPK3/ERK3. MAP2K4 is phosphorylated, and thus activated by MAP3K1/MEKK. Knockout studies in mice suggest roles for this kinase in mediating survival signal in T cell development, as well as in the organogenesis of liver. Applications: Suitable for use in Western Blot and Immunohistochemistry....
