EEF2K (Ps366) Blocking Peptide – >85% Purity

This gene encodes 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. [provided by RefSeq, Jul 2008]

EEF2K: an atypical protein kinase of the Alpha family. Dependent on Ca2 ions and calmodulin. May play a key role linking cellular energy status and the inhibition of protein synthesis, a major consumer of metabolic energy. Phosphorylates and inactivates eEF2, resulting in the inhibition of peptide-chain elongation eEF2K is phosphorylated and activated by AMPK in response to elevated AMP levels, which increase during cellular stress and starvation. Regulated in response to a range of stimuli including TNF-alpha. Overexpressed in breast cancer cell lines and tumors. Activated in rat glioblastoma, and growth was inhibited by the drug Rottlerin. Activity induced in ischemic heart muscle
