Differential distribution of factors involved in pre-mRNA processing in the yeast cell nucleus [PDF]
The yeast cell nucleus has previously been shown to be divided into two regions by a variety of microscopic approaches. We used antibodies specific for the 2,2,7-trimethylguanosine cap structure of small nuclear ribonucleic acids (snRNAs) and for a ...

HCETSR, derived from tRNA‐Glu/TTC, binds to SPTBN1, promoting the dissociation of SPTBN1 from the catenin complex and facilitating the translocation of the catenin complex from the cell membrane to the nucleus. Meanwhile, HCETSR reduces proteasomal degradation of β‐catenin and synthesis of nascent β‐catenin.

Evolution of alternative RNA-splicing [PDF]
Pojava alternativnog prekrajanja nesumnjivo predstavlja iznimno važan korak u evoluciji eukariota. Iako nije poznato kada se točno pojavilo, zasigurno je od tada snažno povećalo kodirajući potencijal genoma.

In Vitro Studies of the Prp9·Prp11·Prp21 Complex Indicate a Pathway for U2 Small Nuclear Ribonucleoprotein Activation [PDF]
Pre-mRNA splicing takes place on a large ribonucleoprotein particle, the spliceosome which contains the five small nuclear ribonucleoproteins (snRNPs), U1, U2, U4, U5, and U6. In Saccharomyces cerevisiae the mRNA splicing factors, Prp9, Prp11, and Prp21,

Mud2 functions in transcription by recruiting the Prp19 and TREX complexes to transcribed genes [PDF]
The different steps of gene expression are intimately linked to coordinate and regulate this complex process. During transcription, numerous RNA-binding proteins are already loaded onto the nascent mRNA and package the mRNA into a messenger ...

SmD3 regulates intronic noncoding RNA biogenesis [PDF]
Accumulation of excess lipid in nonadipose tissues is associated with oxidative stress and organ dysfunction and plays an important role in diabetic complications.

Biomolecular condensates segregate nuclei into discrete regions, facilitating the execution of distinct biological functions. Here, it is identified that the WW domain containing adaptor with coiled‐coil (WAC) is localized to nuclear speckles via its WW ...

Common lines modeling for reference free ab-initio reconstruction in cryo-EM
We consider the problem of estimating an unbiased and reference-free ab-inito model for non-symmetric molecules from images generated by single-particle cryo-electron microscopy.

Purification and characterization of pre-mRNA splicing factor SF2 from HeLa cells [PDF]
SF2, an activity necessary for 5' splice site cleavage and lariat formation during pre-mRNA splicing in vitro, has been purified to near homogeneity from HeLa cells. The purest fraction contains only two related polypeptides of 33 kD.
