The spliceosome as a transposon sensor [PDF]
The ability to distinguish self from non-self nucleic acids enables eukaryotes to suppress mobile elements and maintain genome integrity. In organisms from protist to human, this function is performed by RNA silencing pathways. There have been major advances in our understanding of the RNA silencing machinery, but the mechanisms by which these pathways

RNAtomy of the Spliceosome's heart [PDF]
In his 1543 monumental work De humanis corpori fabrica , Andreas Vesalius used rigorous dissection practices and a mechanistic view of the organ's function to provide the first accurate anatomical description of a human heart. Guided by similar principles of meticulous structural probing and mechanistic explanatory potential, Anokhina and colleagues in

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

Structural basis for dual roles of Aar2p in U5 snRNP assembly [PDF]
Yeast U5 small nuclear ribonucleoprotein particle (snRNP) is assembled via a cytoplasmic precursor that contains the U5-specific Prp8 protein but lacks the U5-specific Brr2 helicase.

The spliceosome inhibitors isoginkgetin and pladienolide B induce ATF3-dependent cell death.
The spliceosome assembles on pre-mRNA in a stepwise manner through five successive pre-spliceosome complexes. The spliceosome functions to remove introns from pre-mRNAs to generate mature mRNAs that encode functional proteins.

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 ...

RNA splicing: Unexpected spliceosome diversity [PDF]
A novel form of spliceosome, containing the minor snRNPs U11 and U12, splices a class of pre-mRNA introns with non-consensus splice sites. This unexpected spliceosome diversity has interesting implications for the evolution and expression of eukaryotic ...

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.
