Supplementary information

EIF1A also known as Eukaryotic Initiation Factor 1A plays an important role in the process of initiating translation. It has a mass of approximately 17.5 kDa. This factor is expressed in various tissues playing a role in forming the pre-initiation complex ensuring mRNA and ribosomal alignment. eIF1A's structure and binding capabilities make it an essential component for the fidelity and efficiency of translation initiation.
Biological function summary

EIF1A functions as part of the eukaryotic translation initiation complex. It stabilizes the binding of the small ribosomal subunit to mRNA. eIF1A works closely with other initiation factors including eIF1 eIF3 and eIF5 to facilitate the proper scanning of mRNA for the correct start codon. This precise role in translation initiation serves as a regulatory point for protein synthesis in cells.

Pathways

EIF1A engages in the mRNA translation pathway particularly in the initiation phase. It is critical in ensuring the mRNA translation accuracy by preventing premature joining of the large ribosomal subunit. eIF1A associates with proteins like eIF3 and eIF2 during the initial stages of translation. This involvement ensures cellular homeostasis and efficient cellular response to various stimuli.

EIF1A may influence cancer development and progression. Alterations in its expression levels or mutations can disrupt normal translation processes potentially leading to oncogenesis. Research indicates a connection between eIF1A and tumor suppressor proteins highlighting its impact on cellular proliferation. Additionally eIF1A may relate to neurodegenerative disorders by affecting proteins such as eIF2 impacting neuronal translation control and protein synthesis regulation.

Target data

Component of the 43S pre-initiation complex (43S PIC), which binds to the mRNA cap-proximal region, scans mRNA 5'-untranslated region, and locates the initiation codon (PubMed : 9732867). This protein enhances formation of the cap-proximal complex (PubMed : 9732867). Together with EIF1, facilitates scanning, start codon recognition, promotion of the assembly of 48S complex at the initiation codon (43S PIC becomes 48S PIC after the start codon is reached), and dissociation of aberrant complexes (PubMed : 9732867). After start codon location, together with EIF5B orients the initiator methionine-tRNA in a conformation that allows 60S ribosomal subunit joining to form the 80S initiation complex (PubMed : 35732735). Is released after 80S initiation complex formation, just after GTP hydrolysis by EIF5B, and before release of EIF5B (PubMed : 35732735). Its globular part is located in the A site of the 40S ribosomal subunit (PubMed : 35732735). Its interaction with EIF5 during scanning contribute to the maintenance of EIF1 within the open 43S PIC (PubMed : 24319994). In contrast to yeast orthologs, does not bind EIF1 (PubMed : 24319994).
