Detection of Human/Mouse/Rat MKK6 by Western Blot.
Western blot shows lysates of HepG2 human hepatocellular carcinoma cell line, C2C12 mouse myoblast cell line, TS1 mouse helper T cell line, and B16-F1 mouse melanoma cell line. PVDF membrane was probed with 0.05 µg/mL Rabbit Anti-Human/Mouse/Rat MKK6 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF1604) followed by HRP-conjugated Anti-Rabbit IgG Secondary Antibody (Catalog # HAF008). For additional reference, recombinant human MKK6 (2 ng) was included. A specific band for MKK6 was detected at approximately 38 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Mitogen-activated protein kinase kinase 6 (MKK6), also known as MEK6, and the closely related MKK3 are activated by pro-inflammatory cytokines and environmental stresses (1, 2). Both MKK3 and MKK6 are dual specificity protein kinases, phosphorylating and activating the p38 MAP kinases at Thr and Tyr positions within the phosphoacceptor sequence Thr-Gly-Tyr (3). Activation of MKK6 occurs through phosphorylation at Ser207 and Thr211 (4) by several upstream MAPK kinase kinases, including ASK1 and TAK1 (5, 6). Purification of E. coli-expressed wild-type active MKK6 capable of p38 alpha phosphorylation has been previously noted (7).
