FKF1/GIGANTEA light-inducible transcription system
Multi-Component SwitchThe FKF1/GIGANTEA light-inducible transcription system is an optogenetic multi-component switch for mammalian cells built from the Arabidopsis photoreceptor FKF1 and its binding partner GIGANTEA. In an optimized split FKF1/GI dimerized Gal4-VP16 configuration, light induces transcriptional activation by reconstituting a functional transcriptional regulator.
