Structural insights into spliceosome fidelity: DHX35-GPATCH1 mediated rejection of aberrant splicing substrates
In this project, we investigated how the spliceosome bound to an excised intron-lariat is remodeled and how the associated intron-lariat is debranched during the process collectively known as spliceosome termination. We used a native pulldown from a C. elegans strain carrying an endogenous tag on th...

The spliceosome, a highly dynamic macromolecular assembly, catalyzes the precise removal of introns from pre-mRNAs. Recent studies have provided comprehensive structural insights in the step-wise assembly, catalytic splicing and final disassembly of the spliceosome. However, the molecular details of...

After removing an intron from pre-mRNA, the spliceosome becomes trapped in a non productive complex bound to the excised intron. The termination of this complex is critical for spliceosome recycling and intron decay, but the underlying mechanism remains unknown. Here, we present cryo-electron micros...

We determined that over 60 spliceosomal proteins are conserved between many fungal species and humans but were lost during the evolution of S. cerevisiae, an intron-poor yeast with unusually rigid splicing signals. We analyzed null mutations in a subset of these factors, most of which had not been i...
