RNA splicing is an essential, precisely regulated process that occurs after gene transcription and before mRNA translation. A gene is first transcribed into a pre-mRNA, which is a copy of the genomic DNA containing intronic regions destined to be removed during pre-mRNA processing (RNA splicing)...
The spliceosome must assemble onto each intron to catalyse its excision, and this assembly is controlled by a large number of pre-mRNA-binding proteins. Alternative splicing can produce many different kinds of insertions and deletions in the final mature mRNA, and these changes can drastically alter...
SARS-CoV-2 RNA-protein interactions NSP1 NSP8 NSP9 NSP16 interferon mRNA splicing translation protein trafficking Introduction Coronaviruses are a family of viruses with notably large single-stranded RNA genomes and broad species tropism among mammals (Graham and Baric, 2010). Recently, a coronavirus...
Nonsense-mediated mRNA decay (NMD) is a translation-dependent mechanism of RNA decay that probably evolved to eliminate abnormal transcripts that are a consequence of routine abnormalities in gene expression. However, NMD also targets naturally occurring transcripts, such as certain alternatively spliced ...
Transcribe the DNA - What would be the mRNA? Can mRNA be changed after transcription? What is mRNA processing? Explain how small RNA (sRNAs) molecules can regulate the translation of a piece of mRNA. Explain how a eukaryotic gene with a single promoter and one intron would have its pre-mR...

Alternative pre-mRNA splicing is a critical mechanism that generates multiple mRNA from a single gene, thereby increasing the diversity of the proteome. Recent research has highlighted the significance of specific splicing isoforms in cellular processes,

(r2<0.6 for 57% of genes, <0.1 for 24% of genes, Fig.2b). Thus, in most genes that harbored both eQTLs and sQTLs, these were driven by independent signals. This is illustrated byRGS1, encoding a regulator of G-protein signaling, which has independent variants affecting either mRNA ...
Expression of mRNA is often regulated by the binding of a small RNA (miRNA, snoRNA, siRNA). While the pairing contribution to the net free energy is well parameterized and can be computed in O(N) time, the cost of removing pre-existing mRNA secondary structure has not received sufficient ...
