EIF4A3 also known as DDX48 is an ATP-dependent RNA helicase. It unwinds RNA secondary structures in an energy-dependent manner being an important part in RNA metabolic processes. eIF4A3 has a molecular mass of approximately 46 kDa and is ubiquitously expressed in various tissues and cell types. It localizes in both the cytoplasm and nucleus indicating its involvement in diverse cellular functions.
Biological function summary
EIF4A3 engages in nonsense-mediated mRNA decay and plays a role in mRNA splicing. It is an important component of the exon junction complex (EJC) which includes other proteins like MAGOH and Y14. This complex ensures proper mRNA surveillance by marking transcripts that need to be subject to degradation if errors are found.
Pathways
EIF4A3 interacts with cellular processes such as mRNA surveillance and splicing. It integrates within the nonsense-mediated decay (NMD) pathway and the spliceosome-associated pathways. eIF4A3's activity closely relates to proteins like UPF1 and RNPS1 which coordinate the removal of defective mRNA and support mRNA splicing.
EIF4A3 has connections with cancer and neurodegenerative diseases. Aberrant expression of eIF4A3 links to tumor progression where its role in RNA processing becomes dysregulated. Moreover in neurodegenerative disorders like spinal muscular atrophy eIF4A3 interacts with proteins such as SMN leading to deficits in mRNA processing which contributes to disease pathology.
