Background Information
EIF4A3 is a component of the exon junction complex (EJC), which assembles near exon-exon junctions of mRNAs as a result of splicing. EJC proteins involves in postsplicing events, including mRNA export, cytoplasmic localization, and nonsense-mediated decay. Its RNA-dependent ATPase and RNA-helicase activities are induced by CASC3, but abolished in presence of the MAGOH/RBM8A heterodimer, thereby trapping the ATP-bound EJC core onto spliced mRNA in a stable conformation. Besides, it involved in translational enhancement of spliced mRNAs after formation of the 80S ribosome complex and binds spliced mRNA in sequence-independent manner, 20-24 nucleotides upstream of mRNA exon-exon junctions

Publications
What published studies show
The EIF4A3 Monoclonal antibody (1G6H9), catalog number 67740-1-Ig, has 2 total citations. These appear in Genes Dev (2026) and RNA (2022). Both studies used the antibody for Western blot in human samples and focus on the exon junction complex (EJC)—one investigating cotranscriptional exon inclusion coordination, and the other examining KIF1C-mediated EJC transport in neuronal cells. The associated research fields include RNA biology, mRNA splicing, and neurobiology.
