Eukaryotic translation elongation factor 2

Elongation Factor 2, EF-2, NPR-C, eEF2
This gene encodes a member of the GTP-binding translation elongation factor family. This protein is an essential factor for protein synthesis. It promotes the GTP-dependent translocation of the nascent protein chain from the A-site to the P-site of the ribosome. This protein is completely inactivated by EF-2 kinase phosporylation.

Papers on Elongation Factor 2
Hexavalent chromium induces expression of mesenchymal and stem cell markers in renal epithelial cells.
New
Kuo et al., Kao-hsiung, Taiwan. In Mol Carcinog, 24 Feb 2015
By revealing that levels of dihydrodiol dehydrogenase were promptly reduced following Cr(VI) challenge, our data suggested that DDH could be involved in a Cr(VI)-related oxidation to generate massive reactive oxygen species and H2 O2 , and to create intracellular hypoxia, which then increased levels of SUMO-1 activating enzyme subunit 2, and sumoylation of eukaryotic elongation factor-2, to mediate the subsequent molecular and cellular responses, e.g., expression of mesenchymal and stem cell markers.
mTORC1-mediated translational elongation limits intestinal tumour initiation and growth.

Sansom et al., Paris, France. In Nature, 22 Feb 2015

Structure of the Elongator cofactor complex Kti11/Kti13 provides insight into the role of Kti13 in Elongator-dependent tRNA modification.
New
Séraphin et al., Illkirch-Graffenstaden, France. In Febs J, 21 Feb 2015
Kti11 was additionally shown to be implicated in the biosynthesis of diphthamide, a post-translationally modified histidine of translation elongation factor 2. Recent data indicate that iron-bearing Kti11 functions as an electron donor to the [4Fe-4S] cluster of radical SAM enzymes triggering the subsequent radical reaction.
Resistance exercise induced S6K1 kinase activity is not inhibited in human skeletal muscle despite prior activation of AMPK by high-intensity interval cycling.

Cryo-EM of Ribosomal 80S Complexes with Termination Factors Reveals the Translocated Cricket Paralysis Virus IRES.
New

Here, we present cryoelectron microscopy (cryo-EM) maps of 80S⋅CrPV-STOP⋅eRF1⋅eRF3⋅GMPPNP and 80S⋅CrPV-STOP⋅eRF1 complexes, revealing a previously unseen binding state of the IRES and directly rationalizing that an eEF2-dependent translocation of the IRES is required to allow the first A-site occupation.
Alcohol Intoxication Following Muscle Contraction in Mice Decreases Muscle Protein Synthesis But Not mTOR Signal Transduction.

Lang et al., State College, United States. In Alcohol Clin Exp Res, 31 Jan 2015
This decrease was associated with impaired protein elongation as EtOH increased the phosphorylation of eEF2 Thr(56) .
