Light-sensitive proteins are useful tools to control protein localization and gene expression, but are currently limited to excitation with red or blue light. Here Crefcoeur et al. present a novel optogenetic system to induce protein–protein interactions with ultraviolet-B light that does not require exogenous chromophores.
