Description_x000D_ General description_x000D_ EEF2K is a highly conserved calmodulin-dependent protein kinase that links activation of cell surface receptors to cell division. EEF2K is involved in the regulation of protein synthesis. It phosphorylates eukaryotic elongation factor 2 (EEF2), an abundant cytoplasmic protein that catalyzes the movement of the ribosome along mRNA during translation in eukaryotic cells, and inhibits the EEF2 function. EEF2K is highly expressed in heart and skeletal muscle, suggesting that EEF2 phosphorylation may be particularly important in muscle. EEF2K is highly expressed in patients with systemic lupus erythematosus as well as in many cancers._x000D_ Physical form_x000D_ Supplied in 50mM Tris-HCl, pH 7.5, 150mM NaCl, 10mM glutathione, 0.1mM EDTA, 0.25mM DTT, 0.1mM PMSF, 25% glycerol._x000D_ Preparation Note_x000D_ after opening, aliquot into smaller quantities and store at -70 °C.
