ABSTRACT

Light inducible protein-protein interactions are powerful tools to manipulate biological processes. Genetically encoded light-gated proteins for controlling precise cellular behavior are a new and promising technology, called optogenetics. Here we exploited the blue light-induced transcription system in yeast and zebrafish, based on the blue light dependent interaction between two plant proteins, blue light photoreceptor Cryptochrome 2 (CRY2) and the bHLH transcription factor CIB1 (CRY-interacting bHLH 1). We demonstrate the utility of this system by inducing rapid transcription suppression and activation in zebrafish.
