Fig. 1 A model for cytoplasmic NMD. Pre ter, premature termination codon; Intron, the 3′-most intron; Norm ter, normal termination codon; thin vertical line, 3′-most exon–exon junction. Nucleus-associated NMD is comparable except for taking place before or during mRNA export to the cytoplasm. Current Biology 2002 12, R196-R197DOI: (10.1016/S0960-9822(02)00747-9)
