Opis

General description

MAP Kinase Kinase (MAPKK, MEK1 and MEK2) belong to a family of enzymes that activates their substrate by dual phosphorylation at threonine and tyrosine residues. MEK1 and MEK2 have 86% homology in their catalytic domain. Activation of MEK1/2 is mediated in mitogen-stimulated cells by Raf-1 kinase. MEK1/2 then activates ERK1/2 leading to the activation of several downstream targets that contribute to cell proliferation, apoptosis and motility. In addition to ERK1/2, there may be non-catalytic effectors of MEK1/2. MEK isoforms appear to be widely expressed in the central nervous system, thymus, spleen, heart, lung, and kidney. Active forms of MEK1/2 are sufficient for the transformation of NIH3T3 cells of the differentiation of PC-12 cells.
The antibody specifically recognizes MEK1/2 (45 kDa) only when phosphorylated at Ser²¹⁷ and Ser²²¹. It reacts strongly with MEK1/2 phosphorylated only at Ser²¹⁷, but less when phosphorylated only at Ser²²¹. It shows not cross reaction with any other related family members including SEK.

Immunogen

synthetic phosphopeptide Ser^217/221 corresponding to residues around Ser^217/221 of human MEK 1/2.

Application

Anti-phospho-MAP Kinase Kinase 1/2 (MEK1/2) has a wide range of applications. The recommended working dilution for immunoblotting in serum treated NIH3T3 cells is 1:1000. For immunoprecipitation, a working dilution of 1:50 may be used. For detection by immunohistochemistry in paraffin-embedded human breast carcinoma sections, antibody dilution of 1:100 may be used. For immunocytochemistry (immunofluorescence), in HeLa cells, a working dilution of 1:1000 may be used.

Biochem/physiol Actions

Detects MEK 1/2 when phosphorylated at Ser²¹⁷ and Ser²²¹. It does not react with non-phosphorylated MEK 1/2, SEK (MKK4), MKK3, or MKK6.

Physical form

Solution in 10 mM HEPES, pH 7.5, containing 150 mM sodium chloride, 100 μg/ml bovine serum albumin and 50% glycerol.
