Species cross-reactivity is determined by western blot.
Applications Key: W=Western Blotting, IP=Immunoprecipitation
Species predicted to react based on 100% sequence homology: Chicken, Xenopus.
Specificity / Sensitivity
MEK1/2 Antibody detects endogenous levels of total MEK1/2 protein. The antibody does not cross-react with related kinases such as SEK (MKK4), MKK3 or MKK6.
Source / Purification
Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to the sequence of human MEK1/2. Antibodies are purified by protein A and peptide affinity chromatography.
MEK1 and MEK2, also called MAPK or Erk kinases, are dual-specificity protein kinases that function in a mitogen activated protein kinase cascade controlling cell growth and differentiation (1-3). Activation of MEK1 and MEK2 occurs through phosphorylation of two serine residues at positions 217 and 221, located in the activation loop of subdomain VIII, by Raf-like molecules. MEK1/2 is activated by a wide variety of growth factors and cytokines and also by membrane depolarization and calcium influx (1-4). Constitutively active forms of MEK1/2 are sufficient for the transformation of NIH/3T3 cells or the differentiation of PC-12 cells (4). MEK activates p44 and p42 MAP kinase by phosphorylating both threonine and tyrosine residues at sites located within the activation loop of kinase subdomain VIII.
