The combination of an F-box domain with a single-domain antibody that recognizes green fluorescent protein (GFP) now allows controlled depletion of GFP fusions in mammalian cells and in flies. This system, called deGradFP, should be widely useful, as GFP fusions are available for many proteins in model organisms.
