We aimed to study the cleavage sites of nonsense-mediated mRNA decay (NMD) substrates. Therefore, we depleted the major exoribonuclease XRN1 in human cell culture, which degrades the 3' fragments generated by SMG6-mediated endonucleolytic cleavage. Different reporter mRNAs or endogenous NMD targets ...
