Electron tomography reveals posttranscriptional binding of pre-mRNPs to specific fibers in the nucleoplasm [PDF]

open access: yes, 2000
International audienceUsing electron tomography, we have analyzed whether the Balbiani ring (BR) pre-mRNP particles in transit from the gene to the nuclear pore complex (NPC) are bound to any structure that could impair free diffusion through the ...

Retroelement origins of pre‐mRNA splicing [PDF]

open access: yesWIREs RNA, 2020
AbstractRecent cryo‐EM structures of a group II intron caught in the process of invading DNA have given new insight into the mechanisms of both splicing and retrotransposition. Conformational dynamics involving the branch‐site helix domain VI are responsible for substrate exchange between the two steps of splicing.

Unraveling the mechanism of recognition of the 3' splice site of the adenovirus major late promoter intron by the alternative splicing factor PUF60.

open access: yesPLoS ONE, 2020
Pre-mRNA splicing is critical for achieving required amounts of a transcript at a given time and for regulating production of encoded protein. A given pre-mRNA may be spliced in many ways, or not at all, giving rise to multiple gene products.

Regulation of age-dependent expression patterns of five transcription factors in Larix kaempferi

open access: yesForestry Research, 2023
To reveal the regulatory mechanisms underlying age-dependent expression patterns, we characterized seven age-related genes, LaDAL1, LaAGL2-2, LaAGL2-3, LaAGL11, LaSOC1-1, LaAP2-1, and LaAP2-2 in terms of transcription and intron splicing in Larix ...

Pre-mRNA splicing in disease and therapeutics [PDF]

open access: yesTrends in Molecular Medicine, 2012
In metazoans, alternative splicing of genes is essential for regulating gene expression and contributing to functional complexity. Computational predictions, comparative genomics, and transcriptome profiling of normal and diseased tissues indicate that an unexpectedly high fraction of diseases are caused by mutations that alter splicing.

Mutations in the U5 snRNA result in altered splicing of subsets of pre-mRNAs and reduced stability of Prp8

open access: yes, 2009
The U5 snRNA loop 1 aligns the 5' and 3' exons for ligation during the second step of pre-mRNA splicing. U5 is intimately associated with Prp8, which mediates pre-mRNA repositioning within the catalytic core of the spliceosome and interacts directly with

Defective splicing of the background K+ channel K2P5.1 by the pre-mRNA splicing inhibitor, pladienolide B in lectin-activated mouse splenic CD4+ T cells

open access: yesJournal of Pharmacological Sciences, 2016
The two-pore domain K+ channel K2P5.1 has been implicated in the pathogenesis of autoimmune diseases. We investigated the changes in K2P5.1 activity caused by a defect in normal pre-mRNA splicing in concanavalin A-activated mouse splenic CD4+ T cells ...

Post-transcriptional regulation of 5-lipoxygenase mRNA expression via alternative splicing and nonsense-mediated mRNA decay

open access: yes, 2012
5-Lipoxygenase (5-LO) catalyzes the two initial steps in the biosynthesis of leukotrienes (LT), a group of inflammatory lipid mediators derived from arachidonic acid.

Abnormal splicing of ABCA1 pre-mRNA in Tangier disease due to a IVS2 +5G>C mutation in ABCA1 gene

open access: yesJournal of Lipid Research, 2003
Two point mutations of ABCA1 gene were found in a patient with Tangier disease (TD): i) G>C in intron 2 (IVS2 +5G>C) and ii) c.844 C>T in exon 9 (R282X).

Interaction of yeast eIF4G with spliceosome components Implications in pre-mRNA processing events

open access: yes, 2009
As evidenced from mammalian cells the eukaryotic translation initiation factor eIF4G has a putative role in nuclear RNA metabolism. Here we investigate whether this role is conserved in the yeast Saccharomyces cerevisiae.
