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 ...

A complex molecular machine, the spliceosome, ensures that the genetic information from the genome, after being transcribed ...

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 ...

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 ...

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 : ...

Spliceosome mutations represent a new generation of acquired genetic alterations that affect both myeloid and lymphoid malignancies. A substantial proportion of patients with myelodysplastic ...

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 ...

Malfunctions in the spliceosome lead to diseases known as spliceosomopathies, which may affect many different tissues, and manifest as retinal degeneration or myelodysplastic syndrome, a group of ...

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 ...
