A hPrp28 mutant stalls spliceosome assembly before complex B. To dissect the role of the DEAD-box protein hPrp28 during human spliceosomal B complex formation, we first assayed the effect of an ...

Post-transcriptional maturation of pre-mRNAs involves a number of processes that are now known to interact with transcription itself. Mutations affecting early spliceosome assembly, but not a drug ...

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 ...

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 ...

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 : ...

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 ...

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 ...
