Western Blotting (WB), Immunofluorescence (IF), Immunohistochemistry (Paraffin-embedded Sections) (IHC (p))
Specificity
SEK1/MKK4 (phospho-Ser80) antibody detects endogenous levels of SEK1/MKK4 only when phosphorylated at Serine 80.
Purification
Affinity Chromatography using epitope-specific phosphopeptide. The antibody against non-phosphopeptide was removed by chromatogramphy using non-phosphopeptide corresponding to the phosphorylation site.
Immunogen
The antiserum was produced against synthesized phosphopeptide derived from human SEK1/MKK4 around the phosphorylation site of serine 80 (T-H-Sp-I-E).

(Mitogen-Activated Protein Kinase Kinase 4 (MAP2K4))
MEK4 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. This kinase is phosphorylated, and thus activated by MAP3K1 / MEKK. The knockout studies in mice suggested the roles of this kinase in mediating survival signal in T cell development, as well as in the organogenesis of liver.Synonyms: Dual specificity mitogen-activated protein kinase kinase 4, JNK-activating kinase 1, MAP Kinase Kinase 4, MAPKK4, MEK-4, MKK4, PRKMK4, SAPK/ERK kinase 1, SERK1, c-Jun N-terminal kinase kinase 1
