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 ...

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.

bioRxiv, 2022 The spliceosome is a staggeringly complex machine comprising, in humans, 5 snRNAs and >150 proteins. We scaled haploid CRISPR-Cas9 base editing to target the entire human spliceosome and interrogated the mutants using the U2 snRNP/SF3b inhibitor ...

Structural basis of branch site recognition by the human spliceosome
Science, 2021 Description Intron recognition in the spotlight Excision of noncoding introns from pre–messenger RNAs is catalyzed by the spliceosome, a large RNA-protein complex that recognizes specific sequences at the exon-intron boundaries (splice sites).

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.

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.

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 ...

Nature Communications, 2020 The role of dysregulation of mRNA alternative splicing (AS) in the development and progression of solid tumors remains to be defined. Here we describe the first comprehensive AS landscape in the spectrum of human prostate cancer (PCa) evolution.

Human spliceosomal snRNA sequence variants generate variant spliceosomes
RNA, 2021 Human pre-mRNA splicing is primarily catalyzed by the major spliceosome, comprising five small nuclear ribonucleoprotein complexes, U1, U2, U4, U5, and U6 snRNPs, each of which contains the corresponding U-rich snRNA. These snRNAs are encoded by large gene families exhibiting significant sequence variation, but it remains unknown if most human snRNA ...
