Trypanosomatidae is a family of early branching eukaryotes harbouring a distinctive repertoire of gene expression strategies. Functional mature messenger RNA is generated via the trans-splicing and polyadenylation processing of constitutively transcribed

In Vitro Studies of the Prp9·Prp11·Prp21 Complex Indicate a Pathway for U2 Small Nuclear Ribonucleoprotein Activation [PDF]
Pre-mRNA splicing takes place on a large ribonucleoprotein particle, the spliceosome which contains the five small nuclear ribonucleoproteins (snRNPs), U1, U2, U4, U5, and U6. In Saccharomyces cerevisiae the mRNA splicing factors, Prp9, Prp11, and Prp21,

αCP binding to a cytosine-rich subset of polypyrimidine tracts drives a novel pathway of cassette exon splicing in the mammalian transcriptome. [PDF]
Alternative splicing (AS) is a robust generator of mammalian transcriptome complexity. Splice site specification is controlled by interactions of cis-acting determinants on a transcript with specific RNA binding proteins.

Interaction of yeast eIF4G with spliceosome components Implications in pre-mRNA processing events [PDF]
International audienceAs 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.

Challenging the spliceosome machine [PDF]
Abstract Background Using cDNA copies of transcripts and corresponding genomic sequences from the Berkeley Drosophila Genome Project, a set of 24,753 donor and acceptor splice sites were computed with a scanning algorithm that tested for single nucleotide insertion, deletion and substitution ...

Circadian rhythms and post-transcriptional regulation in higher plants [PDF]
The circadian clock of plants allows them to cope with daily changes in their environment. This is accomplished by the rhythmic regulation of gene expression, in a process that involves many regulatory steps.

Targeting the Spliceosomal Protein USP39 Through Allosteric Ligands and PROTAC-Induced Degradation. [PDF]
Proteolysis‐targeting chimeras (PROTACs) enable degradation of proteins previously considered undruggable by harnessing the cellular ubiquitin–proteasome system. In this study, Schäfer et al. identify thiazole‐based small molecules that allosterically bind the zinc finger domain of ubiquitin‐specific protease 39 (USP39), a non‐enzymatic scaffold ...

Characterization of a disease-associated mutation affecting a putative splicing regulatory element in intron 6b of the cystic fibrosis transmembrane conductance regulator (CFTR) gene [PDF]
Cystic fibrosis (CF) is a common recessive disorder caused by >1600 mutations in the CF transmembrane conductance regulator (CFTR) gene. About 13% of CFTR mutations are classified as “splicing mutations,” but for almost 40% of these, their role in ...

Spliceosome Mutations in Uveal Melanoma [PDF]
Uveal melanoma (UM) is the most common primary intraocular malignancy of the eye. It has a high metastatic potential and mainly spreads to the liver. Genetics play a vital role in tumor classification and prognostication of UM metastatic disease. One of the driver genes mutated in metastasized UM is subunit 1 of splicing factor 3b (SF3B1), a component ...

The 35S U5 snRNP is generated from the activated spliceosome during In vitro splicing [PDF]
Primary gene transcripts of eukaryotes contain introns, which are removed during processing by splicing machinery. Biochemical studies In vitro have identified a specific pathway in which introns are recognised and spliced out. This occurs by progressive
