Spliceosome Structure and Function [PDF]
Pre-mRNA splicing is catalyzed by the spliceosome, a multimegadalton ribonucleoprotein (RNP) complex comprised of five snRNPs and numerous proteins. Intricate RNA-RNA and RNP networks, which serve to align the reactive groups of the pre-mRNA for catalysis, are formed and repeatedly rearranged during spliceosome assembly and catalysis.

SnapShot: Spliceosome Dynamics I
Spliceosomes are multi-megadalton RNA-protein molecular machines that carry out pre-mRNA splicing, that is, the removal of non-coding intervening sequences (introns) from eukaryotic pre-mRNAs and the ligation of neighboring coding regions (exons) to produce mature mRNA for protein biosynthesis on the ribosome.

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 ...

U12 type introns were lost at multiple occasions during evolution
Background Two categories of introns are known, a common U2 type and a rare U12 type. These two types of introns are removed by distinct spliceosomes. The phylogenetic distribution of spliceosomal RNAs that are characteristic of the U12 spliceosome, i.e.

The Natural Product N-Palmitoyl-l-leucine Selectively Inhibits Late Assembly of Human Spliceosomes*
Background: Compounds that inhibit spliceosomes are of very limited availability. Results: A high-throughput screen of a marine bacteria natural products library identified a promising lead compound that inhibits pre-mRNA splicing in vitro. Conclusion: N-

Endogenous U2·U5·U6 snRNA complexes in S. pombe are intron lariat spliceosomes
During logarithmic growth, Schizosaccharomyces pombe cells contain abundant, high-molecular-weight complexes harboring U2, U5, and U6 snRNAs. Chen et al.

Identifying RNA splicing factors using IFT genes in Chlamydomonas reinhardtii [PDF]
Intraflagellar transport moves proteins in and out of flagella/cilia and it is essential for the assembly of these organelles. Using whole-genome sequencing, we identified splice site mutations in two IFT genes,
