Structure of spliceosomal ribonucleoproteins [PDF]
F1000 Biology Reports, 2010 Splicing of the precursors of eukaryotic mRNA and some non-coding RNAs is catalyzed by the 'spliceosome', which comprises five RNA-protein complexes (small nuclear ribonucleoproteins, or snRNPs) that assemble in an ordered manner onto precursor-mRNAs. Much progress has been made in determining the gross morphology of spliceosomal assembly intermediates.

Pseudouridines in spliceosomal snRNAs [PDF]
Protein & Cell, 2011 Spliceosomal RNAs are a family of small nuclear RNAs (snRNAs) that are essential for pre-mRNA splicing. All vertebrate spliceosomal snRNAs are extensively pseudouridylated after transcription. Pseudouridines in spliceosomal snRNAs are generally clustered in regions that are functionally important during splicing.

Srsf10 and the minor spliceosome control tissue-specific and dynamic SR protein expression
eLife, 2020 Minor and major spliceosomes control splicing of distinct intron types and are thought to act largely independent of one another. SR proteins are essential splicing regulators mostly connected to the major spliceosome.

SF3b4: A Versatile Player in Eukaryotic Cells
Frontiers 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 ...

The MUC1 extracellular domain subunit is found in nuclear speckles and associates with spliceosomes. [PDF]
PLoS ONE, 2012 MUC1 is a large transmembrane glycoprotein and oncogene expressed by epithelial cells and overexpressed and underglycosylated in cancer cells. The MUC1 cytoplasmic subunit (MUC1-C) can translocate to the nucleus and regulate gene expression.

Brr2p-mediated conformational rearrangements in the spliceosome during activation and substrate repositioning [PDF]
, 2012 Brr2p is one of eight RNA helicases involved in pre-mRNA splicing. Detailed understanding of the functions of Brr2p and other spliceosomal helicases has been limited by lack of knowledge of their in vivo substrates. To address this, sites of direct Brr2p–

Splicing diversity revealed by reduced spliceosomes in C. merolae and other organisms
RNA Biology, 2015 Pre-mRNA splicing has been considered one of the hallmarks of eukaryotes, yet its diversity is astonishing: the number of substrate introns for splicing ranges from hundreds of thousands in humans to a mere handful in certain parasites.

Cellular bases of the RNA metabolism dysfunction in motor neurons of a murine model of spinal muscular atrophy: Role of Cajal bodies and the nucleolus [PDF]
, 2017 Spinal muscular atrophy (SMA) is caused by a homozygous deletion or mutation in the survival motor neuron 1 (SMN1) gene that leads to reduced levels of SMN protein resulting in degeneration of motor neurons (MNs).
