Accurate identification of the translation initiation codon is critical to ensure the synthesis of the correct cellular proteins in the proper amounts. In eukaryotes, translation initiation generally occurs by a cap-dependent scanning mechanism, wherein the small (40S) subunit of the ribosome recruits methionyl initiator tRNA (Met-tRNAi) in a ternary complex (TC) with GTP-bound eukaryotic initiation […]
