Detection of Human/Mouse/Rat MEK1 by Western Blot. Western blot shows lysates of BT-20 human breast cancer cell line, U937 human histiocytic lymphoma cell line, DU145 human prostate carcinoma cell line, and mouse brain tissue. PVDF membrane was probed with 0.2 µg/mL Goat Anti-Human/Mouse/Rat MEK1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF2079) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF109). For additional reference, recombinant human MEK1 (5 ng) was included. A specific band for MEK1 was detected at approximately 45 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

MEK1 and MEK2, also known as MAP2K1 and MAP2K2, are activated in response to mitogenic stimuli. Activation occurs through dual phosphorylation at S218/S222 of MEK1 and S222/S226 of MEK2 by several upstream MAP3Ks. Both MEK1 and MEK2 are dual-specificity protein kinases, phosphorylating and activating ERK1 and ERK2 at Thr and Tyr positions.
