Detection of Human MAP3K8/Tpl2/COT by Western Blot. Western blot shows lysates of Jurkat human acute T cell leukemia cell line and MO7e human megakaryocytic leukemic cell line. PVDF Membrane was probed with 1 µg/mL of Human MAP3K8/Tpl2/COT Monoclonal Antibody (Catalog # MAB4586) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF007). Specific bands were detected for MAP3K8/Tpl2/COT at approximately 58 and 52 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

MAP3K8, also called Tpl2 (tumor progression locus 2) or COT (Cancer Osaka Thyroid oncogene) is a cytosolic Ser/Thr kinase. MAP3K8 is one of the MAP kinase kinase (MAPKK) kinases that regulates the ERK1/ERK2 pathway in response to IL-1, facilitating IL-8 and MIP-1 beta production. MAP3K8 activates I kappa B kinases and induces the nuclear production of NF-kappa B. Human MAP3K8 shares 97% and 98% amino acid (aa) identity with mouse and rat MAP3K8, respectively, within the region used as an immunogen. Alternative start sites can give a 58 kDa (467 aa) isoform with stronger activity but shorter half-life than a 52 kDa (397 aa) isoform.
