SF3b4: A Versatile Player in Eukaryotic Cells

open access: yesFrontiers in Cell and Developmental Biology, 2020
Spliceosomes are large protein-RNA complexes regulating pre-mRNA processing in eukaryotes. SF3b4 encodes a core subunit of the U2-type spliceosome, loss- or gain-of-function of which often associates with abnormal cell growth, leading to tumorigenesis ...

Engineering Crystal Packing in RNA-Protein Complexes II: A Historical Perspective from the Structural Studies of the Spliceosome

open access: yesCrystals, 2021
Cryo-electron microscopy has greatly advanced our understanding of how the spliceosome cycles through different conformational states to conduct the chemical reactions that remove introns from pre-mRNA transcripts.

Structural basis for dual roles of Aar2p in U5 snRNP assembly [PDF]

open access: yes, 2013
Yeast U5 small nuclear ribonucleoprotein particle (snRNP) is assembled via a cytoplasmic precursor that contains the U5-specific Prp8 protein but lacks the U5-specific Brr2 helicase.

The Role of E6 Spliced Isoforms (E6*) in Human Papillomavirus-Induced Carcinogenesis

open access: yesViruses, 2018
Persistent infections with High Risk Human Papillomaviruses (HR-HPVs) are the main cause of cervical cancer development. The E6 and E7 oncoproteins of HR-HPVs are derived from a polycistronic pre-mRNA transcribed from an HPV early promoter.

Mutations in the splicing regulator Prp31 lead to retinal degeneration in Drosophila

open access: yesBiology Open, 2021
Retinitis pigmentosa (RP) is a clinically heterogeneous disease affecting 1.6 million people worldwide. The second-largest group of genes causing autosomal dominant RP in human encodes regulators of the splicing machinery.

Rapidly evolving protointrons in Saccharomyces genomes revealed by a hungry spliceosome. [PDF]

open access: yes, 2019
Introns are a prevalent feature of eukaryotic genomes, yet their origins and contributions to genome function and evolution remain mysterious. In budding yeast, repression of the highly transcribed intron-containing ribosomal protein genes (RPGs ...

SnapShot: Spliceosome Dynamics I

open access: yesCell, 2015
Spliceosomes are multi-megadalton RNA-protein molecular machines that carry out pre-mRNA splicing, that is, the removal of non-coding intervening sequences (introns) from eukaryotic pre-mRNAs and the ligation of neighboring coding regions (exons) to produce mature mRNA for protein biosynthesis on the ribosome.

RNA-Seq analysis of splicing in Plasmodium falciparum uncovers new splice junctions, alternative splicing and splicing of antisense transcripts. [PDF]

open access: yes, 2011
Over 50% of genes in Plasmodium falciparum, the deadliest human malaria parasite, contain predicted introns, yet experimental characterization of splicing in this organism remains incomplete.

Alternative splicing: transcriptional regulatory network in agroforestry

open access: yesFrontiers in Plant Science, 2023
Alternative splicing (AS) in plants plays a key role in regulating the expression of numerous transcripts from a single gene in a regulatory pathway. Variable concentrations of growth regulatory hormones and external stimuli trigger alternative splicing ...

A splicing-dependent transcriptional checkpoint associated with prespliceosome formation [PDF]

open access: yes, 2014
There is good evidence for functional interactions between splicing and transcription in eukaryotes, but how and why these processes are coupled remain unknown.
