Nonsense-mediated RNA decay (NMD) is a highly conserved and selective RNA turnover pathway that depends on the endonuclease SMG6. Here, we show that SMG6 is essential for male germ cell differentiation in mice. Germ-cell conditional knockout (cKO) of Smg6 induces extensive transcriptome misregulatio...

Mature mRNAs undergo quality control during translation that may lead to RNA degradation by triggering the nonsense mediated decay (NMD) pathway. Aberrant translation due to features such as the presence of a premature stop codon downstream on an exon-exon junction or an intron in the 3'UTR activate...

RNA was isolated from control and Smg6 deficient ES cells using the TRIzol (Invitrogen) reagent by following the company manual. For all samples the RNA integrity was checked using an Agilent Bioanalyzer 2100. All samples showed a RIN (RNA integrity number) of higher than 9. Approximately 2.5 M-BM-5...

Total RNA sequencing in neuroprogenitors after SMG6 deletion
Quantitative profiling of SMG6 cleavage sites in HEK293 cells
In metazoans, the endoribonuclease SMG6 is thought to cleave many endogenous mRNAs targeted for nonsense-mediated mRNA decay (NMD). However, most evidence as to the identity of endogenous SMG6 substrates is indirect, and little is known about their cleavage sites. Here, we report the efficacy of an ...

Nonsense-mediated mRNA decay (NMD) relies on the coordinated assembly and action of multiple protein factors. Degradation of target mRNAs begins with endonucleolytic cleavage near premature stop codons, but the mechanisms of endonuclease activation and regulation remain unclear. Using structural pre...

Circadian gene expression study of SMG6 and WT mouse livers
The nonsense-mediated mRNA decay pathway targets specific mRNAs for degradation in a translation-dependent manner. NMD can induce RNA turnover via either the bulk mRNA deadenylation and decapping machinery or via the specialized SMG6 endonuclease. SMG6 is a magnesium-dependent nuclease, leading to t...
