Rapidly reversible manipulation of molecular activity with dual chemical dimerizers.

The rapid, inducible, reversible modulation of molecular activities by dual CID systems. Rapamycin (Rapa) treatment induces relocation of FRB-POI to the GAIs-FKBP-C2(LACT)-labeled plasma membrane and activates POI-dependent signaling event. A subsequent GA3-AM treatment induces second relocation of a whole GAIs-FKBP-C2(LACT)/rapamycin/FRB-POI complex from the plasma membrane to the Tom20-GID1-labeled mitochondria and leads to termination of POI-dependent signaling.
