Now, Hiten Madhani of the University of California, San Francisco, and colleagues have implicated the spliceosome, a molecular complex that excises introns from pre-messenger RNAs (pre-mRNAs), in ...

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 ...

For many eukaryotic introns, splicing is done in a series of reactions which are catalyzed by the spliceosome, a complex of small nuclear ribonucleoproteins (snRNPs) and associated proteins ...

The vast majority of introns are removed by the major spliceosome, a 60 S complex containing five small nuclear RNAs (snRNAs: U1, U2, U4, U5 and U6) and well over 50 different polypeptides (Fig.

This so-called splicing process is catalysed in the cell's nucleus by the spliceosome, a highly complex and dynamic molecular machine. It is composed of numerous protein and RNA components and it is ...

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 ...
