Biomolecular condensates are membrane-less organelles enriched in specific proteins and nucleic acids, compartmentalized to perform biochemical functions. Such condensates are formed by the process of phase separation enabled by protein domains that allow for multivalent interactions. Chromosomal translocation-derived in-frame gene-fusions often result in proteins with non-native domain combinations and re-wire protein-protein interaction networks. Several recent studies have shown that for a subset of the fusion proteins, pathogenesis can be driven by the fusion protein’s ability to undergo phase transitions at non-physiologic cellular locations to form ectopic condensates. Here, we highlight how such ectopic phase transitions can alter biological processes and posit that dysfunction via protein phase separation at non-physiologic locations represents a generic route to oncogenic transformation.
