WebJan 11, 2008 · Eukaryotic initiation factor (eIF) 1 is a small protein (12 kDa) governing fidelity in translation initiation. It is recruited to the 40 S subunit in a multifactor complex with Met-tRNA(i)(Met), eIF2, eIF3, and eIF5 and binds near the P-site. eIF1 release in response to start codon recognition is an important signal to produce an 80 S initiation complex.

WebDec 21, 2024 · eIF1 plays a dual role in translation initiation. It promotes the open conformation of the PIC, to which TC rapidly loads in the P OUT conformation, and it ensures initiation fidelity by blocking P i release and impeding isomerization to the closed/P IN state at non-AUG codons or start codons in poor context (Figure 1A ). The function of eIf1 has some hidden aspects. However, in all eukaryotic cells initiation of mRNA translation starts with scanning via ribosomal 43S preinitiation complexes starting from the 5’ end of the mRNA.
