Spliceosomes are large and dynamic RNA-protein complexes. The major spliceosome consists of five subunits, U1, U2, U4, U6, and U5 small nuclear ribonucleoprotein particles (snRNPs, read "snurps ...

Their findings reveal that spliceosome subunits U4, U5 and U6 are normally stabilized as a complex by a protein called USP39. However, when subunits are mutated or USP39 is absent, the stability ...

This process is controlled by a large protein-RNA complex called the spliceosome. MIT biologists have now discovered a new layer of regulation that helps to determine which sites on the messenger ...

The spliceosome then converts them into mature, functional mRNA. To do this, this large protein-RNA complex, which is located in the cell nucleus, removes non-coding sections (introns) from mRNA ...

Then the RNA binding protein communicates to the splicing machinery to include or not include the exon into the mRNA,” Cooper explained. The fit between a splice site and the spliceosome components ...

Plants survive cold by adjusting at cellular level. Scientists discovered that the PORCUPINE protein helps plants adapt to ...

Spliceosome structures have been investigated extensively in the past decade, but most of the studies have been restricted to ...

Researchers from the German Diabetes Center (DDZ) and the Heinrich Heine University Dusseldorf (HHU) have studied the ...

Discovery of a novel nuclear protein complex with interaction via the WW domain ... including type II membrane proteins, a spliceosome component, as well as RNA helicase, and ...

Biologists have discovered a new type of RNA-splicing regulation that helps to determine which protein-coding exons will be included in messenger RNA transcripts. RNA splicing is a cellular ...
