Western blot - Anti-MEK3 (phospho S189/T193) + MEK6 (phospho S207/T211) antibody (AB4759)

Peptide Competition : Extracts prepared from background extracts with Mal-E tagged fusion protein expressing MEK 6 left inactivated (6) or with MEKK added for activation (1-5) were resolved by SDS-PAGE on a 10% polyacrylamide gel and transferred to PVDF. Membranes were blocked with a 5% BSA-TBST buffer overnight at 4^oC, then were incubated with 0.50 μg/mL ab4759 antibody for two hours at room temperature in a 3% BSA-TBST buffer, following prior incubation with : no peptide (1, 6), the non-phosphopeptide corresponding to the phosphopeptide immunogen (2), a generic hosphoserine-containing peptide (3), a generic phosphothreonine-containing peptide (4), or the phosphopeptide immunogen (5). After washing, the membrane was incubated with goat F(ab"e;)2 anti-rabbit IgG alkaline phosphatase and signals were detected. The data show that only the phosphopeptide corresponding to MEK3/6 [pSpT189/193]/[pSpT207/211] blocks the antibody signal, demonstrating the specificity of the antibody. Please note that the Mal-E-tagged fusion protein expressing MEK6 runs at ~81 kDa.

제품 세부 정보

Mitogen Activated Protein Kinase Kinases 3 and 6 (MEK 3/6 or MKK 3/6) are 42 kDa members of a tyrosine/threonine protein kinase family that activate p38, which is part of the inflammation/stress signaling pathway. Phosphorylation of MEK3 and 6 by MEKK1 on serine 189 and threonine 193 (serine 207 and threonine 211 for MEK6) in the catalytic domain activates the proteins and enables them to phosphorylate p38.

Purification 관련 사항

Purified from rabbit serum by sequential epitope-specific chromatography. The antibody has been negatively preadsorbed using a non-phosphopeptide corresponding to the site of phosphorylation to remove antibody that is reactive with non-phosphorylated MEK 3. The final product is generated by affinity chromatography using a MEK 3 derived peptide that is phosphorylated at serine 189 and threonine 193.

MEK3 also known as MAP2K3 and MEK6 also referred to as MAP2K6 are kinases in the mitogen-activated protein kinase (MAPK) signaling pathway. Mechanically MEK3 and MEK6 phosphorylate and activate p38 MAPKs which play important roles in cellular responses to stress and inflammation. MEK3 has a molecular mass of approximately 39 kDa and is widely expressed in various tissues including brain lung and liver. Similarly MEK6 is about 37 kDa in mass and shows expression in heart lung skeletal muscle and other tissues. Phosphorylation occurs at serine (S189 for MEK3 S207 for MEK6) and threonine (T193 for MEK3 T211 for MEK6) residues which are key to their activation.

Biological function summary

MEK3 and MEK6 function as essential components in the MAPK signaling cascade. These kinases work as upstream regulators that modulate the activity of p38 MAPK part of a larger MAPK complex. MEK3 and MEK6 transduce extracellular signals that trigger numerous cellular processes like differentiation apoptosis and response to stress stimuli. Their role influences a range of biological activities such as cell growth and survival indicating a vital role in maintaining cellular homeostasis.

Pathways

MEK3 and MEK6 are critical in the MAPK and the p38 MAPK signaling pathways. These pathways mediate responses to pro-inflammatory cytokines and environmental stress. Both kinases have connections to other proteins like MKK3 MKK6 and p38 MAPK translating extracellular cues into suitable cellular responses. Their function within these pathways impacts inflammatory responses and cell cycle regulation exemplifying their importance in cellular communication networks.

MEK3 and MEK6 relations include inflammatory conditions and cancer. Aberrant activation of these kinases leads to disease pathologies like rheumatoid arthritis and certain types of cancer. Moreover associations exist with other key proteins such as p38 MAPKs in these pathways which play important roles in disease progression. Understanding MEK3 and MEK6 roles allows for insights into developing targeted therapies for diseases linked to these kinases.

타겟 정보

Dual specificity kinase. Is activated by cytokines and environmental stress in vivo. Catalyzes the concomitant phosphorylation of a threonine and a tyrosine residue in the MAP kinase p38. Part of a signaling cascade that begins with the activation of the adrenergic receptor ADRA1B and leads to the activation of MAPK14.
