Molecular basis for the activation of human spliceosome
The spliceosome executes pre-mRNA splicing through four sequential stages: assembly, activation, catalysis, and disassembly. Activation of the spliceosome, namely remodeling of the pre-catalytic spliceosome (B complex) into the activated spliceosome ...

The spliceosome is a large ribonucleoprotein complex that catalyzes the removal of introns from RNA polymerase II-transcribed RNAs. Spliceosome assembly occurs in a stepwise manner through specific intermediates referred to as pre-spliceosome complexes E,

PRP4: a protein of the yeast U4/U6 small nuclear ribonucleoprotein particle [PDF]
The Saccharomyces cerevisiae prp mutants (prp2 through prp11) are known to be defective in pre-mRNA splicing at nonpermissive temperatures. We have sequenced the PRP4 gene and shown that it encodes a 52-kilodalton protein.

SNUPN‐Related Muscular Dystrophy: Novel Phenotypic, Pathological and Functional Protein Insights
ABSTRACT Objective SNUPN‐related muscular dystrophy or LGMDR29 is a new entity that covers from a congenital or childhood onset pure muscular dystrophy to more complex phenotypes combining neurodevelopmental features, cataracts, or spinocerebellar ataxia. So far, 12 different variants have been described.

The DEAH-box NTPase Prp43 and its cofactors Ntr1 and Ntr2 form the NTR complex and are required for disassembling intron-lariat spliceosomes (ILS) and defective earlier spliceosomes.

Introns: the “dark matter” of the eukaryotic genome
The emergence of introns was a significant evolutionary leap that is a major distinguishing feature between prokaryotic and eukaryotic genomes. While historically introns were regarded merely as the sequences that are removed to produce spliced ...

A Quantitative Approach to Investigating the Hypothesis of Prokaryotic Intron Loss [PDF]
Using a novel method, we show that ordered triplets of motifs usually associated with spliceosomal intron recognition are underrepresented in the protein coding sequence of complete Thermotogae, archaeal and bacterial genomes.

Identification of Five Putative Yeast RNA Helicase Genes [PDF]
The RNA helicase gene family encodes a group of eight homologous proteins that share regions of sequence similarity. This group of evolutionarily conserved proteins presumably all utilize ATP (or some other nucleoside triphosphate) as an energy source ...

This study reports that SBNO1 protein is upregulated in several cancer entities. SBNO1 protein interacts with the basal transcription factor TFIID via TAF4, enabling its recruitment to transcription start sites and the modulation of target gene expression.

Small molecule inhibitors of pre-mRNA splicing are important tools for identifying new spliceosome assembly intermediates, allowing a finer dissection of spliceosome dynamics and function. Here, we identified a small molecule that inhibits human pre-mRNA
