Targeting eukaryotic elongation factor 2 kinase (eEF2K) with small-molecule inhibitors for cancer therapy

Eukaryotic elongation factor 2 kinase (eEF2K) is a member of the α-kinase family that is activated by calcium/calmodulin. Of note, eEF2K is crucial for regulating translation and is often highly overexpressed in malignant cells. Therefore in this review, we summarize the molecular structure of eEF2K and its oncogenic roles in cancer. Moreover, we further discuss the inhibition of eEF2K with small-molecule inhibitors and other new emerging therapeutic strategies in cancer therapy. Taken together, these inspiring findings provide new insights into a promising strategy for inhibiting eEF2K to greatly improve future cancer therapy.
