Eukaryotic elongation factor-2 kinase (eEF-2 kinase), also known as calcium/calmodulin-dependent eukaryotic elongation factor 2 kinase (CaMKIII) is an enzyme that in humans is encoded by the EEF2K gene.[1][2]


eEF-2 kinase is a highly conserved protein kinase in the calmodulin-mediated signaling pathway that links activation of cell surface receptors to cell division. This kinase is involved in the regulation of protein synthesis. It phosphorylates eukaryotic elongation factor 2 (EEF2) and thus inhibits the EEF2 function. The activity of this kinase is increased in many cancers and may be a valid target for anti-cancer treatment.[1][3]
