How far ‘AUG-proximity effect’ goes?
Pereira, Francisco J.C.; Teixeira, Alexandre; Kong, Jian; Silva, Ana Luísa; Liebhaber, Stephen A.; Romão, LuísaNonsense-mediated mRNA decay (NMD) is a surveillance pathway that recognizes and selectively degrades mRNAs carrying premature termination codons (PTCs). We have previously shown that mRNAs carrying a PTC located in close proximity to the translation initiation AUG codon escape NMD. This was called the “AUG-proximity effect”. The present work illustrates that the extension of the AUG-proximity effect, i.e. to w...
Interaction of PABPC1 with the translation initiation complex is critical to th...
Peixeiro, Isabel; Inácio, Ângela; Barbosa, Cristina; Silva, Ana Luísa; Liebhaber, Stephen; Romão, LuísaNonsense-mediated mRNA decay (NMD) is a surveillance pathway that recognizes and rapidly degrades mRNAs containing premature termination codons (PTC). The strength of the NMD response appears to reflect multiple determinants on a target mRNA. We have previously reported that mRNAs containing PTCs in close proximity to the translation initiation codon (AUG-proximal PTCs) can substantially evade NMD. Here, we exp...
