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.

psiCLIP reveals dynamic RNA binding by DEAH-box helicases before and after exon ligation
Nature Communications, 2021 ATP-dependent helicases remodel the spliceosome and proofread splice site recognition. A new method – Purified Spliceosome iCLIP (psiCLIP) – probes protein-RNA interactions in defined spliceosome complexes to reveal how the helicases Prp16 and Prp22 ...

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.

Localized inhibition of protein phosphatase 1 by NUAK1 promotes spliceosome activity and reveals a MYC-sensitive feedback control of transcription. [PDF]
, 2020 Deregulated expression of MYC induces a dependence on the NUAK1 kinase, but the molecular mechanisms underlying this dependence have not been fully clarified.

Therapeutic potential of CDK11 in cancer
Clinical and Translational Medicine, 2023 Human cyclin‐dependent kinases (CDKs) direct the progression of the cell cycle and transcription. They are deregulated in tumours, and despite their involvement in the regulation of basic cellular processes, many CDKs are promising targets for cancer ...

Transcriptome Analysis of the Cerebellum of Mice Fed a Manganese-Deficient Diet
Frontiers in Genetics, 2020 Manganese (Mn), primarily acquired through diet, is required for brain function and development. Epidemiological studies have found an association between both low and high levels of Mn and impaired neurodevelopment in children.

Pre-mRNA splicing-associated diseases and therapies
RNA Biology, 2023 Precursor mRNA (pre-mRNA) splicing is an essential step in human gene expression and is carried out by a large macromolecular machine called the spliceosome.

Viruses, 2022 The spliceosome is a massive ribonucleoprotein structure composed of five small nuclear ribonucleoprotein (snRNP) complexes that catalyze the removal of introns from pre-mature RNA during constitutive and alternative splicing. EFTUD2, PRPF8, and SNRNP200

The spliceosome inhibitors isoginkgetin and pladienolide B induce ATF3-dependent cell death.
PLoS ONE, 2020 The spliceosome assembles on pre-mRNA in a stepwise manner through five successive pre-spliceosome complexes. The spliceosome functions to remove introns from pre-mRNAs to generate mature mRNAs that encode functional proteins.

USP15 regulates dynamic protein-protein interactions of the spliceosome through deubiquitination of PRP31. [PDF]
, 2017 Post-translational modifications contribute to the spliceosome dynamics by facilitating the physical rearrangements of the spliceosome. Here, we report USP15, a deubiquitinating enzyme, as a regulator of protein-protein interactions for the spliceosome ...
