Mechanistic links between nonsense-mediated mRNA decay and pre-mRNA splicing in mammalian cells.

Abstract

Nonsense-mediated mRNA decay (NMD) generally involves nonsense codon recognition by translating ribosomes at a position approximately 25 nts upstream of a splicing-generated exon junction complex of proteins. As such, NMD provides a means to degrade abnormal mRNAs that encode potentially deleterious truncated proteins. Additionally, an estimated one-third… (More)
