Human NMD ensues independently of stable ribosome stalling
Abstract
Nonsense-mediated mRNA decay (NMD) was thought to ensue when ribosomes fail to terminate translation properly. However, the authors observe similar ribosome occupancy at stop codons of NMD sensitive and insensitive mRNAs, showing that human NMD is not activated by stable ribosome stalling as previously suggested.
