Anti-eEF2: Mouse eEF2 Antibody


BACKGROUND Ribosomal protein synthesis is one of the oldest and best-conserved processes taking place in a living cell. Amino acid residues are added to the growing peptide chain in the ribosome by an elongation process that involves two GTP-switched elongation factors, denominated EF1 and EF2 in eukaryotes. EF1-GTP brings the aminoacyl-tRNA (as the so-called ternary complex) to the acceptor site on the ribosome. After the nascent protein chain is transpeptidated to the newly arrived tRNA, EF2 catalyzes a conformational switch of the organelle, such that the newly generated peptidyl-tRNA is moved from the acceptor site to the peptidyl site, liberating the former for a new round of elongation. EF2 is a large (more than 800-residue), probably multifunctional, and remarkable protein that apparently binds to the same ribosomal structures as the EF1-GTP–aminoacyl-tRNA complex.

eEF2 (eukaryotic translation elongation factor 2) is 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. eEF2 is phosphorylated and inhibited by a calcium/calmodulin-dependent protein kinase called eEF2 kinase, which modifies Thr56 and Thr58. Phosphorylation at Thr56 and Thr58 results in the inactivation of eEF2 by causing a structural alteration that reduces its affinity for the ribosome, thereby preventing its ability to catalyze translocation.1 eEF2 kinase is also subjected to regulation by phosphorylation, and a number of phosphorylation sites have been identified that lead to subsequent activation or inhibition of activity.2,3
