Anti-MAP3K14 antibodies are used in the immunodetection of the protein mitogen-activated protein kinase kinase kinase 14. In humans, the canonical protein has a reported length of 947 amino acid residues and a mass of 104 kDa. Its subcellular localization is in the cytoplasm. It is reported to be weakly expressed in the testis, small intestine, spleen, thymus, peripheral blood leukocytes, prostate, ovary and colon. A member of the STE Ser/Thr protein kinase protein family, MAP3K14 is known to be involved with immune response pathways. Post-translational modifications have been described, including ubiquitination and phosphorylation. Synonyms for this target antigen include HS, HSNIK, NIK, NF-kappa-beta-inducing kinase, serine/threonine-protein kinase NIK, and FTDCR1B. MAP3K14 gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. Over 140 citations in the literature describe the use of MAP3K14 antibodies in research. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
