Eukaryotic elongation factor-2 kinase (eEF-2k) previously known as +/calmodulin-dependent protein kinase III, is an abundant cytoplasmic protein highly specific for elongation factor-2 (eEf-2) (1). Phosphorylation of eEF-2 by eEF-2 kinase on specific threonine residues results in the inactivation of eEF-2 and in termination of mRNA translation 2). The activity of eEF2 kinase is not only dependent upon Ca2+ ions, calmodulin (CaM) and insulin, but is also regulated
both negatively and positively by phosphorylation by different protein kinases (AMPK, S6K1, p90 RSK) (3-4). There is also evidence that eEF-2 phosphorylation is involved in the regulation of cell cycle progression, cellular differentiation, oogensis and malignant tumors (5-6).
Applications:
Suitable for use in Western Blot Immunoprecipitation. Other applications not tested.
Recommended Dilutions:
Western Blot: 1: 5,000-50,000
Immunoprecipitation: 1:20
Optimal dilutions to be determined by the researcher.
Storage and Stability:
May be stored at 4 degrees C for short-term only. For long-term storage, store at -20 degrees C. Aliquots are stable for at least 12 months at -20 degrees C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
