Bidirectional coupling of splicing and ATM signaling in response to transcription-blocking DNA damage [PDF]
In response to DNA damage cells activate intricate protein networks to ensure genomic fidelity and tissue homeostasis. DNA damage response signaling pathways coordinate these networks and determine cellular fates, in part, by modulating RNA metabolism ...

Structure of spliceosomal ribonucleoproteins [PDF]
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.

Srsf10 and the minor spliceosome control tissue-specific and dynamic SR protein expression
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
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 ...

Pseudouridines in spliceosomal snRNAs [PDF]
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.

Brr2p-mediated conformational rearrangements in the spliceosome during activation and substrate repositioning [PDF]
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
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.
