The 35S U5 snRNP is generated from the activated spliceosome during In vitro splicing [PDF]
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

Spliceosomal snRNA Epitranscriptomics [PDF]
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 nucleus. snRNPs participate in pre-mRNA splicing by recognizing the critical sequence elements present

RNA splicing: a split consensus reveals two major 5' splice site classes. [PDF]
The established consensus sequence for human 5’ splice sites masks the presence of two major splice site classes defined by preferential base-pairing potentials with either U5 snRNA loop 1 or the U6 snRNA ACAGA box.

Spliceosome assembly and regulation: insights from analysis of highly reduced spliceosomes. [PDF]
Premessenger RNA splicing is catalyzed by the spliceosome, a multimegadalton RNA–protein complex that assembles in a highly regulated process on each intronic substrate. Most studies of splicing and spliceosomes have been carried out in human orS. cerevisiaemodel systems.

Spliceosomal immunophilins [PDF]
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.

Turning on the Spliceosome [PDF]
The spliceosome is the complex macromolecular machine responsible for removing introns from pre-mRNAs. The processes of spliceosome assembly and activation rely on the coordinated interactions of many dozens of spliceosome components to identify splice sites in a pre-mRNA, build a spliceosome, and activate the spliceosome for catalysis by formation of ...

Spliceosomal intronogenesis [PDF]
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.

Which Kind of Causal Specificity Matters Biologically? [PDF]
Griffiths et al. (2015) have proposed a quantitative measure of causal specificity and used it to assess various attempts to single out genetic causes as being causally more specific than other cellular mechanisms, for example, alternative splicing ...

Spliceosome Database: a tool for tracking components of the spliceosome [PDF]
The spliceosome is the extremely complex macromolecular machine responsible for pre-mRNA splicing. It assembles from five U-rich small nuclear RNAs (snRNAs) and over 200 proteins in a highly dynamic fashion. One important challenge to studying the spliceosome is simply keeping track of all these proteins, a situation further complicated by the variety ...

Localized inhibition of protein phosphatase 1 by NUAK1 promotes spliceosome activity and reveals a MYC-sensitive feedback control of transcription. [PDF]
Deregulated expression of MYC induces a dependence on the NUAK1 kinase, but the molecular mechanisms underlying this dependence have not been fully clarified.
