Web26 Dec 2002 · Our analysis identified 1,106 genes that undergo alternative splicing to generate 1,989 alternative mRNA isoforms that are apparent targets for NMD. Such widespread coupling of alternative splicing and NMD may indicate that the cell possesses a large number of irrelevant mRNA isoforms that must be eliminated. WebRecent studies have shown that during the splicing of an mRNA, at least five proteins (SRm160, DEK, RNPS1, Y14, and REF/Aly) are deposited in an exon–exon junction complex (EJC) 20 to 24 nucleotides upstream of the exon–exon junction (Fig. 1; Le Hir et al. 2000 ).
