Perlman syndrome nuclease DIS3L2 controls cytoplasmic non-coding RNAs and provides surveillance pathway for maturing snRNAs [PDF]
The exosome-independent exoribonuclease DIS3L2 is mutated in Perlman syndrome. Here, we used extensive global transcriptomic and targeted biochemical analyses to identify novel DIS3L2 substrates in human cells.

Disruption of pre-mRNA splicing in vivo results in reorganization of splicing factors [PDF]
We have examined the functional significance of the organization of pre-mRNA splicing factors in a speckled distribution in the mammalian cell nucleus. Upon microinjection into living cells of oligonucleotides or antibodies that inhibit pre-mRNA splicing

A role for the Cajal-body-associated SUMO isopeptidase USPL1 in snRNA transcription mediated by RNA polymerase II [PDF]
Cajal bodies are nuclear structures that are involved in biogenesis of snRNPs and snoRNPs, maintenance of telomeres and processing of histone mRNA. Recently, the SUMO isopeptidase USPL1 was identified as a component of Cajal bodies that is essential for ...

Multiple splicing factors are released from endogenous complexes during in vitro pre-mRNA splicing [PDF]
Pre-mRNA splicing occurs in a macromolecular complex called the spliceosome. Efforts to isolate spliceosomes from in vitro splicing reactions have been hampered by the presence of endogenous complexes that copurify with de novo spliceosomes formed on ...

Interactome analysis brings splicing into focus [PDF]
The spliceosome is a huge molecular machine that assembles dynamically onto its pre-mRNA substrates. A new study based on interactome analysis provides clues about how splicing-regulatory proteins modulate assembly of the spliceosome to either activate ...

We have studied by electron microscopy the structures of native small nuclear ribonucleoprotein (snRNP) particles U2 and U5 from HeLa cells. The structure of native U2 snRNP is characterized by a main body 8 nm in diameter with one additional domain about 4 nm long and 6 nm wide.

The transcriptome of the invasive eel swimbladder nematode parasite Anguillicola crassus [PDF]
BACKGROUND: Anguillicola crassus is an economically and ecologically important parasitic nematode of eels. The native range of A. crassus is in East Asia, where it infects Anguilla japonica, the Japanese eel. A. crassus was introduced into European eels,

Trimethylguanosine nucleoside inhibits cross-linking between snurportin 1 and m3G-capped U1 snRNA [PDF]
Macromolecular nuclear import is an energy-and signal-dependent process. The best characterized type of nuclear import consists of proteins carrying the classical NLS that is mediated by the heterodimeric receptor importin α/β. Spliceosomal snRNPs U1, U2,
