USP39 stabilizes the spliceosome (green), which cuts out unneeded parts (grey and purple) of the mRNA. If USP39 is missing, some of the mRNA is poorly processed. This results in misfolded proteins, ...

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 ...

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 ...
