Descripción general
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.

Especificidad
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.
Inmunógeno
synthetic phosphopeptide Ser217/221 corresponding to residues around Ser217/221 of human MEK 1/2.
Aplicación
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.
Forma física
Solution in 10 mM HEPES, pH 7.5, containing 150 mM sodium chloride, 100 μg/ml bovine serum albumin and 50% glycerol.

Phosphorylation-specific antibodies provide a powerful tool for analysing the regulation and activity of proteins in the MAP (mitogen-activated protein) kinase and other signalling pathways. Using synchronized cells, it was observed that phosphorylation-specific antibodies developed against the active form of MKK1/MKK2

The MAP kinase pathway is activated by a wide variety of external signals leading to cell proliferation or differentiation. However, it is not clear whether activation of this pathway is required for cellular responses or whether it is only one

Activation of the mitogen-activated protein/extracellular signal-regulated kinase kinase (MEK)-mitogen-activated protein kinase (MAPK) pathway is a frequent event in tumorigenesis, and analysis of human breast carcinomas demonstrates that 25-50% of these tumors express elevated levels of activated MAPK1/2. However, a direct
