EIF4A1 is an ATP-dependent RNA helicase and core component of the eIF4F translation initiation complex that unwinds secondary RNA structures in the 5'-untranslated region of mRNAs, enabling ribosomal scanning and translation initiation 1. Beyond canonical translation, eIF4A1 functions as an RNA chaperone that limits stress granule formation by reducing RNA-RNA condensation through ATP-dependent RNA binding 2. eIF4A1 is aberrantly upregulated in multiple cancers. In hepatocellular carcinoma and intrahepatic cholangiocarcinoma, eIF4A1 overexpression correlates with poor prognosis and drives proliferation via enhanced translation of oncogenic proteins 34. In triple-negative breast cancer, IGF2BP2 recruits eIF4A1 to enhance m6A-modified CDK6 translation, promoting cell cycle progression 5. Pharmacological eIF4A1 inhibitors (zotatifin) effectively suppress cancer cell growth and enhance sensitivity to targeted therapies 34. Beyond cancer, proteolytic cleavage of eIF4A1 by asparagine endopeptidase in response to chemo/radiotherapy promotes tumor-supportive neuronal senescence through altered PTGES3 mRNA stability 6. eIF4A1 is required for translation initiation quality control, with its depletion impairing ribosomal surveillance mechanisms 7. EIF4A1 mutations appear enriched in virus-associated cancers 8. These findings establish eIF4A1 as a critical translational regulator and promising therapeutic target.
