Function

ATP-dependent RNA helicase (PubMed:16170325). Involved in pre-mRNA splicing as component of the spliceosome (PubMed:11991638, PubMed:22961380, PubMed:28076346, PubMed:28502770, PubMed:29301961). Core component of the splicing-dependent multiprotein exon junction complex (EJC) deposited at splice junctions on mRNAs (PubMed:16170325, PubMed:16209946, PubMed:16314458, PubMed:16923391, PubMed:16931718, PubMed:19033377, PubMed:20479275). The EJC is a dynamic structure consisting of core proteins and several peripheral nuclear and cytoplasmic associated factors that join the complex only transiently either during EJC assembly or during subsequent mRNA metabolism. The EJC marks the position of the exon-exon junction in the mature mRNA for the gene expression machinery and the core components remain bound to spliced mRNAs throughout all stages of mRNA metabolism thereby influencing downstream processes including nuclear mRNA export, subcellular mRNA localization, translation efficiency and nonsense-mediated mRNA decay (NMD). 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. The inhibition of ATPase activity by the MAGOH-RBM8A heterodimer increases the RNA-binding affinity of the EJC. Involved in translational enhancement of spliced mRNAs after formation of the 80S ribosome complex. Binds spliced mRNA in sequence-independent manner, 20-24 nucleotides upstream of mRNA exon-exon junctions. Shows higher affinity for single-stranded RNA in an ATP-bound core EJC complex than after the ATP is hydrolyzed. Involved in the splicing modulation of BCL2L1/Bcl-X (and probably other apoptotic genes); specifically inhibits formation of proapoptotic isoforms such as Bcl-X(S); the function is different from the established EJC assembly (PubMed:22203037). Involved in craniofacial development (PubMed:24360810).

Notes

ab250217 is the carrier-free version of Anti-eIF4A3 antibody [EPR14302(B)] ab180519.

Our RabMAb® technology is a patented hybridoma-based technology for making rabbit monoclonal antibodies. For details on our patents, please refer to RabMAb® patents.

This product is a recombinant monoclonal antibody, which offers several advantages including:

  • - High batch-to-batch consistency and reproducibility
  • - Improved sensitivity and specificity
  • - Long-term security of supply
  • - Animal-free batch production

For more information, read more on recombinant antibodies.

Our carrier-free antibodies are typically supplied in a PBS-only formulation, purified and free of BSA, sodium azide and glycerol. The carrier-free buffer and high concentration allow for increased conjugation efficiency.

This conjugation-ready format is designed for use with fluorochromes, metal isotopes, oligonucleotides, and enzymes, which makes them ideal for antibody labelling, functional and cell-based assays, flow-based assays (e.g. mass cytometry) and Multiplex Imaging applications.

Use our conjugation kits for antibody conjugates that are ready-to-use in as little as 20 minutes with 1 minute hands-on-time and 100% antibody recovery: available for fluorescent dyes, HRP, biotin and gold.

This product is compatible with the Maxpar® Antibody Labeling Kit from Fluidigm, without the need for antibody preparation. Maxpar® is a trademark of Fluidigm Canada Inc.

Activity summary

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.

Associated diseases and disorders

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.
