Regulation of alternative pre-mRNA splicing [PDF]

Briefings in Functional Genomics and Proteomics, 2002
The first wave of bioinformatic studies that followed genome and complementary DNA sequencing projects revealed that alternative splicing of messenger RNA precursors (pre-mRNAs) contributes substantially to transcriptome complexity in higher eukaryotes.

H3K36 Methylation and the Chromodomain Protein Eaf3 Are Required for Proper Cotranscriptional Spliceosome Assembly

Cell Reports, 2019
Summary: In the eukaryotic cell, spliceosomes assemble onto pre-mRNA cotranscriptionally. Spliceosome assembly takes place in the context of the chromatin environment, suggesting that the state of the chromatin may affect splicing.

Perturbation of chromatin structure globally affects localization and recruitment of splicing factors [PDF]

, 2012
Chromatin structure is an important factor in the functional coupling between transcription and mRNA processing, not only by regulating alternative splicing events, but also by contributing to exon recognition during constitutive splicing.

Environmental Stress and Pre-mRNA Splicing [PDF]

Molecular Plant, 2015
Pre-mRNA splicing is an important step for gene expression regulation in plants in response to abiotic stress. In recent years, RNA sequencing (RNA-seq) based on various next-generation sequencing technologies has been used to study dynamic changes of pre-mRNA splicing under conditions of diverse abiotic stress in several plant species.

Interconnections Between RNA-Processing Pathways Revealed by a Sequencing-Based Genetic Screen for Pre-mRNA Splicing Mutants in Fission Yeast

G3: Genes, Genomes, Genetics, 2016
Pre-mRNA splicing is an essential component of eukaryotic gene expression and is highly conserved from unicellular yeasts to humans. Here, we present the development and implementation of a sequencing-based reverse genetic screen designed to identify ...

Characterization of factors involved in the coupling of 3' end processing and splicing and in the 3' end formation of mRNA precursors [PDF]

, 2006
Eukaryotic mRNA precursors are processed at their 5’ and 3’ ends and are spliced prior to their export from the nucleus to the cytoplasm. Although all three processing reactions can be studied separately in vitro, they are coupled in vivo.

Retroelement origins of pre‐mRNA splicing [PDF]

WIREs 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.

SNEV is an evolutionarily conserved splicing factor whose oligomerization is necessary for spliceosome assembly [PDF]

, 2005
We have isolated the human protein SNEV as downregulated in replicatively senescent cells. Sequence homology to the yeast splicing factor Prp19 suggested that SNEV might be the orthologue of Prp19 and therefore might also be involved in pre-mRNA splicing.

Alterations of Alternative Splicing Patterns of Ser/Arg-Rich (SR) Genes in Response to Hormones and Stresses Treatments in Different Ecotypes of Rice (Oryza sativa)

Journal of Integrative Agriculture, 2013
Ser/Arg-rich (SR) genes encode proteins that play pivotal roles in both constitutive and alternative splicing of pre-mRNA. However, not much effort has been made to investigate the alternative splicing of their own pre-mRNA.

Pre-mRNA splicing in disease and therapeutics [PDF]

Trends 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.
