Dimerizers allowing inducible control of protein-protein interactions are powerful tools for manipulating biological processes. Here we describe genetically encoded light-inducible protein interaction modules based on Arabidopsis thaliana cryptochrome 2 and CIB1 that require no exogenous ligands and dimerize on blue light exposure with sub-second time resolution and subcellular spatial resolution. We demonstrate the general utility of this system by inducing protein translocation, transcription, and Cre-mediated DNA recombination using light.
