WebbN2 - Phosphorylation of the alpha subunit of the eukaryotic initiation factor 2 (eIF-2alpha) is one of the best-characterized mechanisms for downregulating protein synthesis in mammalian cells in response to various stress conditions. In Drosophila, such a regulatory mechanism has not been elucidated.

WebbProtein synthesis begins with the formation of an initiation complex. In E. coli , this complex involves the small 30S ribosome, the mRNA template, three initiation factors (IFs; IF-1, IF-2, and IF-3), and a … eIF2 is the main protein complex responsible for delivering the initiator tRNA to the P-site of the preinitiation complex, as a ternary complex containing Met-tRNAi and GTP (the eIF2-TC). eIF2 has specificity for the methionine-charged initiator tRNA, which is distinct from other methionine-charged tRNAs used for elongation of the polypeptide chain. The eIF2 ternary complex remains bound to the P-site while the mRNA attaches to the 40s ribosome and the complex begins to sc…
