Supplementary information

The eukaryotic initiation factor 4A1 also known as eIF4A1 is an essential RNA helicase part of the DEAD-box family. It unwinds secondary structures in the 5' untranslated region of mRNA facilitating ribosome binding during translation initiation. This protein has a molecular mass of approximately 46 kDa. Expressed ubiquitously in eukaryotic cells eIF4A1 plays a central role in regulating protein synthesis by enhancing the accessibility of mRNA templates to the ribosome.
Biological function summary

The eIF4A1 protein functions as a component of the eIF4F complex which includes eIF4E and eIF4G. This complex modulates the initiation of mRNA translation a critical step in gene expression. By associating with other initiation factors eIF4A1 helps orchestrate the recruitment of the ribosome to capped mRNA. Its activity influences cell growth proliferation and response to environmental signals.

Pathways

EIF4A1 involves in the regulation of the mTOR signaling pathway which controls cell growth based on nutrient availability. It also participates in the integrated stress response pathway linking stress signals to translational control. eIF4A1 interacts with other proteins such as eIF4E and eIF4G through its function within these pathways highlighting its role in translation regulation.

EIF4A1 has been implicated in cancer and neurodegenerative diseases. Aberrant regulation of eIF4A1 expression and activity contributes to oncogenesis by promoting uncontrolled protein synthesis and cell proliferation. In neurodegenerative disorders altered eIF4A1 activity disrupts normal neuronal function and viability. Connections to proteins like eIF4E highlight its impact on disease progression emphasizing the importance of understanding eIF4A1's functional mechanisms in these contexts.

Target data

ATP-dependent RNA helicase which is a subunit of the eIF4F complex involved in cap recognition and is required for mRNA binding to ribosome (PubMed : 20156963). In the current model of translation initiation, eIF4A unwinds RNA secondary structures in the 5'-UTR of mRNAs which is necessary to allow efficient binding of the small ribosomal subunit, and subsequent scanning for the initiator codon. As a result, promotes cell proliferation and growth (PubMed : 20156963).
