Anti-MAP2K7 antibodies are used in the immunodetection of the protein mitogen-activated protein kinase kinase 7. In humans, the canonical protein has a reported length of 419 amino acid residues and a mass of 47.5 kDa. Its subcellular localization is in the nucleus and cytoplasm. Up to 4 different isoforms have been reported for this protein. It is notably widely expressed in many tissue types. A member of the STE Ser/Thr protein kinase protein family, MAP2K7 is known to be involved with the apoptotic pathway and the cellular response to lipopolysaccharides. Post-translational modifications have been described, including phosphorylation. Synonyms for this target antigen include MAPKK7, MEK, MEK 7, MKK7, PRKMK7, SAPKK-4, SAPKK4, and JNKK2. MAP2K7 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish and chimpanzee species. Over 90 citations in the literature describe the use of MAP2K7 antibodies in research. Western Blot is a widely used application for these antibodies. ELISA, Immunofluorescence, and Immunohistochemistry are also common applications.
