Exon Junction Complexes: Supervising the Gene Expression Assembly Line.

Abstract excerpt

The exon junction complex (EJC) is an RNA-binding protein complex that is assembled and deposited onto mRNAs during splicing. The EJC comprises four core components that bind to not only canonical sites upstream of exon-exon junctions, but also to noncanonical sites at other positions in exons. EJC-associated proteins are recruited by the EJC at different steps of gene expression to execute the multiple functions...
