[HTML][HTML] Lost in translation: ribosome-associated mRNA and protein quality controls

AL Karamyshev, ZN Karamysheva - Frontiers in genetics, 2018 - frontiersin.org
Aberrant, misfolded, and mislocalized proteins are often toxic to cells and result in many
human diseases. All proteins and their mRNA templates are subject to quality control. There …

Upf proteins: highly conserved factors involved in nonsense mRNA mediated decay

P Gupta, YR Li - Molecular biology reports, 2018 - Springer
Over 10% of genetic diseases are caused by mutations that introduce a premature
termination codon in protein-coding mRNA. Nonsense-mediated mRNA decay (NMD) is an …

[HTML][HTML] Exon junction complex shapes the transcriptome by repressing recursive splicing

L Blazquez, W Emmett, R Faraway, JMB Pineda… - Molecular cell, 2018 - cell.com
Recursive splicing (RS) starts by defining an" RS-exon," which is then spliced to the
preceding exon, thus creating a recursive 5′ splice site (RS-5ss). Previous studies focused …

[HTML][HTML] The exon junction complex undergoes a compositional switch that alters mRNP structure and nonsense-mediated mRNA decay activity

JW Mabin, LA Woodward, RD Patton, Z Yi, M Jia… - Cell reports, 2018 - cell.com
The exon junction complex (EJC) deposited upstream of mRNA exon junctions shapes
structure, composition, and fate of spliced mRNA ribonucleoprotein particles (mRNPs). To …

[HTML][HTML] Mechanism of nonsense-mediated mRNA decay stimulation by splicing factor SRSF1

I Aznarez, TT Nomakuchi, J Tetenbaum-Novatt… - Cell reports, 2018 - cell.com
The splicing factor SRSF1 promotes nonsense-mediated mRNA decay (NMD), a quality
control mechanism that degrades mRNAs with premature termination codons (PTCs). Here …

[HTML][HTML] Exon junction complexes suppress spurious splice sites to safeguard transcriptome integrity

V Boehm, T Britto-Borges, AL Steckelberg, KK Singh… - Molecular cell, 2018 - cell.com
Productive splicing of human precursor messenger RNAs (pre-mRNAs) requires the correct
selection of authentic splice sites (SS) from the large pool of potential SS. Although SS …

[HTML][HTML] ICE1 promotes the link between splicing and nonsense-mediated mRNA decay

TD Baird, KCC Cheng, YC Chen, E Buehler, SE Martin… - Elife, 2018 - elifesciences.org
The nonsense-mediated mRNA decay (NMD) pathway detects aberrant transcripts
containing premature termination codons (PTCs) and regulates expression of 5–10% of non …

[HTML][HTML] Multispecies reconstructions uncover widespread conservation, and lineage-specific elaborations in eukaryotic mRNA metabolism

BP Bannerman, S Kramer, RG Dorrell, M Carrington - PLoS One, 2018 - journals.plos.org
The degree of conservation and evolution of cytoplasmic mRNA metabolism pathways
across the eukaryotes remains incompletely resolved. In this study, we describe a …

The exon junction complex: structural insights into a faithful companion of mammalian mRNPs

JV Gerbracht, NH Gehring - Biochemical Society Transactions, 2018 - portlandpress.com
During splicing, the exon junction complex (EJC) is deposited upstream of exon-exon
boundaries. The EJC and its peripheral bound proteins play an essential role in mediating …
