Protocol Available protocols: Western Blotting Specificity / Sensitivity MEK1/2 (D1A5) Rabbit Monoclonal Antibody (HRP Conjugate) recognizes endogenous levels of total MEK1 and MEK2 proteins. This antibody conjugate is predicted to cross-react with MEK1/MEK2 orthologs in a variety of species. Species Reactivity: Human, Mouse, Rat, Monkey, D. melanogaster Source / Purification Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Ala220 of human MEK1 protein. Background 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.
