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.
