A switching system regulating subcellular localization of nuclear proteins using a viral protease.


We explored a novel approach to the functional regulation of nuclear proteins; altering their subcellular localization. To anchor a nuclear protein, beta-galactosidase with the nuclear localization signal of SV40 (nbeta-gal), within the cytoplasm, nbeta-gal was fused to the transmembrane domain of granulocyte colony-stimulating factor receptor (G-CSFR), a… (More)
