Western blot : Rabbit Monoclonal[EP881Y] to EEF2K ab45168 staining at 1/1000 dilution, shown in green; Mouse anti GAPDH (ab8245) loading control staining at 1/20,000 dilution, shown in magenta. A band was observed at 82 kDa in Wild-type A549 cell lysates with no signal observed at this size in EEF2K knockout A549 cell line. To generate this image, samples were run on an SDS-PAGE gel then transferred onto a nitrocellulose membrane. Membranes were blocked in 3pc Milk in TBS-0.1 % Tween® 20 (TBS-T) before incubation with primary antibodies overnight at 4°C. Blots were washed four times in TBS-T, incubated with secondary antibodies for 1 h at room temperature, washed again four times then imaged. Secondary antibodies used were Goat anti-Rabbit 800CW & Goat anti-Mouse 680RD at 1/20,000 dilution.

Supplementary information

EEF2K also known as eukaryotic elongation factor 2 kinase or CaMKIII is a significant protein kinase with an approximate molecular mass of 85 kDa. EEF2K plays a role in controlling protein synthesis by phosphorylating eukaryotic elongation factor 2 (eEF2) leading to a decrease in its activity. This protein can be found in various tissues throughout the body but shows substantial expression in the brain. It acts as a regulatory switch in translation process under specific cellular conditions.
Biological function summary

EEF2K regulates protein translation and affects cellular energy expenditure during conditions such as starvation or stress. Through its activity EEF2K contributes to the cellular response by phosphorylating eEF2 resulting in modulation of ribosomal function. Although EEF2K does not necessarily form stable complexes with other proteins its function influences several other cellular activities that are in connection with protein synthesis and degradation pathways.

Pathways

EEF2K integrates into nutrient-signaling pathways like the mTOR signaling and the AMPK pathway. These pathways control energy homeostasis and response to cellular stress. EEF2K acts alongside AMPK when nutrient supply is low adjusting protein synthesis rates to meet cellular energy demands. Additionally EEF2K's function inversely relates to mTOR activity which typically promotes protein synthesis and cell growth when conditions are favorable.

EEF2K associates with cancer and neurodegenerative diseases. In cancer EEF2K modulates cell survival under nutrient-poor environments often contributing to chemotherapy resistance. Links between EEF2K and neurodegenerative diseases come from its regulation of protein synthesis which affects neuronal health. Proteins like AMPK connect to EEF2K highlighting their collective contribution to the metabolic rearrangements seen in these disorders.

Target data

Threonine kinase that regulates protein synthesis by controlling the rate of peptide chain elongation. Upon activation by a variety of upstream kinases including AMPK or TRPM7, phosphorylates the elongation factor EEF2 at a single site, renders it unable to bind ribosomes and thus inactive. In turn, the rate of protein synthesis is reduced.
