eIF4AIII binds spliced mRNA in the exon junction complex
Published in Healthcare Finance, Tax and Law Weekly, June 16th, 2004
According to recent research from Brandeis University, "The exon junction complex (EJC), a set of proteins deposited on mRNAs as a consequence of pre-mRNA splicing, is a key effector of downstream mRNA metabolism. We have identified eIF4AIII, a member of the eukaryotic translation initiation factor 4A family of RNA helicases (also known as DExH/D box proteins), as a novel EJC core component."
"Crosslinking and antibody inhibition studies suggest that eIF4AIII constitutes at least part of the platform anchoring other EJC components to spliced mRNAs. A nucleocytoplasmic shuttling protein,...
