Anti-MAP3K2 antibodies are used in the immunodetection of the protein mitogen-activated protein kinase kinase kinase 2. In humans, the canonical protein has a reported length of 619 amino acid residues and a mass of 69.7 kDa. Its subcellular localization is in the nucleus and cytoplasm. It is notably widely expressed in many tissue types. A member of the STE Ser/Thr protein kinase protein family, MAP3K2 is a known component of the protein kinase signal transduction cascade. Post-translational modifications have been described, including ubiquitination and phosphorylation. Synonyms for this target antigen include MEKK2B, MAP/ERK kinase kinase 2, MAPK/ERK kinase kinase 2, MEK kinase 2, MEKK 2, and MEKK2. MAP3K2 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of MAP3K2 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
