Structures of aberrant spliceosome intermediates on their way to disassembly. Nature Structural & Molecular Biology , 2025; DOI: 10.1038/s41594-024-01480-7 Cite This Page : ...

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 ...

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 ...

Think of the spliceosome as an old Transformers robot — it has individual pieces that operate independently but can also come together to form a larger structure. Sometimes, such as in the case of ...

After a decade of work, scientists have completed a molecular model of the human spliceosome, an incredibly complex cellular machine. When an active gene is expressed in a cell, it is transcribed into ...

In human cells, only a small proportion of the information written in genes is used to produce proteins. How does the cell select this information? A large molecular machine called the spliceosome ...

Researchers at the Centre for Genomic Regulation (CRG) have created the first blueprint of the human spliceosome, the complex molecular machine that edits genetic messages transcribed from DNA ...

A complex molecular machine, the spliceosome, ensures that the genetic information from the genome, after being transcribed into mRNA precursors, is correctly assembled into mature mRNA. Splicing ...
