Spliceosomal snRNA Epitranscriptomics [PDF]
Frontiers in Genetics, 2021 Small nuclear RNAs (snRNAs) are critical components of the spliceosome that catalyze the splicing of pre-mRNA. snRNAs are each complexed with many proteins to form RNA-protein complexes, termed as small nuclear ribonucleoproteins (snRNPs), in the cell ...

A model for DHX15 mediated disassembly of A-complex spliceosomes
bioRxiv, 2021 A critical step of pre-mRNA splicing is the recruitment of U2 snRNP to the branch point sequence of an intron. U2 snRNP conformation changes extensively during branch helix formation and several RNA-dependent-ATPases are implicated in the process ...

Spliceosomal immunophilins [PDF]
FEBS Letters, 2008 The spliceosome is a dynamic, macromolecular complex, which removes non‐protein‐coding introns from pre‐mRNA to form mature mRNA in a process known as splicing. This ribonucleoprotein assembly is comprised of five uridine‐rich small nuclear RNAs (snRNAs) as well as over 300 proteins.

Spliceosomal intronogenesis [PDF]
Proceedings of the National Academy of Sciences, 2016 Significance Eukaryotic transcripts contain spliceosomal introns that need to be removed by pre-mRNA splicing. Although several models have been proposed to identify the mechanism of intron gain over the evolution of eukaryotes, they remain models due to a lack of experimental validation.

The 35S U5 snRNP Is Generated from the Activated Spliceosome during In vitro Splicing. [PDF]
PLoS ONE, 2015 Primary gene transcripts of eukaryotes contain introns, which are removed during processing by splicing machinery. Biochemical studies In vitro have identified a specific pathway in which introns are recognised and spliced out. This occurs by progressive

Frontiers in Genetics, 2020 Splicing and alternative splicing of pre-mRNA are key sources in the formation of diversity in the human proteome. These processes have a central role in the regulation of the gene expression pathway.

The minor spliceosomal protein U11/U12-31K is an RNA chaperone crucial for U12 intron splicing and the development of dicot and monocot plants. [PDF]
PLoS ONE, 2012 U12 intron-specific spliceosomes contain U11 and U12 small nuclear ribonucleoproteins and mediate the removal of U12 introns from precursor-mRNAs. Among the several proteins unique to the U12-type spliceosomes, an Arabidopsis thaliana AtU11/U12-31K ...
