In summary, the killswitch is a versatile tool that alters condensate material properties in live cells. It revealed that condensate composition and functions rely on their microenvironments, paving the way for new biology and therapeutic strategies

To analyze compositional changes, we developed NuFANCI, a FACS-based method to isolate nuclear condensates. Applied to killswitch-targeted nucleoli, mass spectrometry revealed selective depletion of ~20 RNA-binding proteins, demonstrating condensate-material-property–dependent partitioning.

Using the nanobody system, killswitch can be targeted to a wide range of endogenous condensates, including nucleoli, nuclear speckles, chromocenters, and disease-specific condensates.

Killswitch (KS) is a non-natural, self-associating micropeptide that can be genetically fused to condensate proteins or recruited via GFP-nanobody. It immobilizes scaffold proteins without affecting soluble pools—letting us perturb condensates selectively in live cells.
