NMD resulting from encephalomyocarditis virus IRES-directed translation initiation seems to be restricted to CBP80/20-bound mRNA.
Nonsense-mediated messenger RNA decay (NMD) generally degrades mRNAs that prematurely terminate translation as a means of quality control. NMD in mammalian cells targets newly spliced mRNA that is bound by the cap-binding protein heterodimer CBP80/20 and one or more post-splicing exon junction complexes during a pioneer round of translation. NMD targets mRNA that initiates translation using the...
متن کاملEvidence for a Pioneer Round of mRNA Translation mRNAs Subject to Nonsense-Mediated Decay in Mammalian Cells Are Bound by CBP80 and CBP20
Nonsense-mediated decay (NMD) eliminates mRNAs that prematurely terminate translation. We used antibody to the nuclear cap binding protein CBP80 or its cytoplasmic counterpart eIF4E to immunopurify RNP containing nonsense-free or nonsense-containing transcripts. Data indicate that NMD takes place in association with CBP80. We defined other components of NMD-susceptible mRNP as CBP20, PABP2, eIF...
متن کاملReinvestigation of the Two-Step Synthesis of Sevoflurane
Improvements in the two-step synthesis of 1,1,1,3,3,3-hexafluoro-2- (fluoromehoxy)propane (Sevoflurane) that result in the product cost reduction, safety level enhancement and positive environmental impacts are described. This process consists of chloromethylation reaction of 1,1,1,3,3,3-hexafluoro-2-propanol (HFIP) followed by a halogen-exchange fluorination. This is the first synthesis of Sev...

متن کاملBoron choreographs a double reaction
sciencemag.org SCIENCE is a long-standing question in geology. Sarafian et al. present a clever set of experiments to determine the impact of small amounts of water on the melting temperature of mantle rock (see the Perspective by Asimow). This allowed them to reinterpret geophysical observations of melting in the mantle and revise estimates of mantle temperature upward. A hotter mantle has a m...
