Structural and Functional Insights into Human Nuclear Cyclophilins
The peptidyl prolyl isomerases (PPI) of the cyclophilin type are distributed throughout human cells, including eight found solely in the nucleus. Nuclear cyclophilins are involved in complexes that regulate chromatin modification, transcription, and pre ...

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

Spliceosomes are the core host of pre-mRNA splicing, allowing multiple protein isoforms to be produced from a single gene. Herein, we reveal that spliceosomes are more abundant in human pluripotent stem cells (hPSs), including human embryonic stem cells (

In this issue of Molecular Cell, Stevens et al. purify a large particle from yeast extracts that contains all five of the U snRNPs required for pre-mRNA splicing. The existence of this "penta-snRNP" suggests the provocative possibility that spliceosome assembly does not depend upon a pre-mRNA substrate.

Inhibición parcial de dos genes que codifican para proteínas del empalmosoma en Giardia intestinalis
Introducción. Giardia intestinalis es un organismo tempranamente divergente en el que recientemente se demostró la presencia de intrones. La maquinaria responsable de la remoción de intrones en organismos eucariotas superiores es el empalmosoma, el cual ...

The DEAH-box NTPase Prp43 and its cofactors Ntr1 and Ntr2 form the NTR complex and are required for disassembling intron-lariat spliceosomes (ILS) and defective earlier spliceosomes.

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

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.
