Spliceosome machinery

Alterations or deregulated expression of genes involved in RNA splicing are recurrently associated to distinct cancer types and/or are linked to splicing events, which generate the pro-migratory proteins isoforms. Precursor messenger RNA splicing is orchestrated by the spliceosome machinery. All-atom simulations are used to unravel the fundamental mechanism underlying splicing in eukaryotes, to understand the molecular basis of constitutive and alternative splicing, the role of cancer associated mutations, and to develop small molecule inhibitors targeting relevant splicing factor.
