Eukaryotic translation initiation factors and regulators

Abstract

Significant progress has been made over the past several years on structural studies of the eukaryotic translation initiation factors that facilitate the assembly of a translation-competent ribosome at the initiation codon of an mRNA. These structural studies have revealed the repeated use of a set of common structural folds, highlighted the evolutionary conservation of the translation apparatus, and provided insight into the mechanism and regulation of cellular and viral protein synthesis.
