Regulation of protein stability is a fundamental process in eukaryotic cells and pivotal to, e.g., cell cycle progression, faithful chromosome segregation, or protein quality control. Synthetic regulation of protein stability requires conditional degradation sequences (degrons) that induce a stability switch upon a specific signal. Fusion to a selected target protein permits to influence virtually every process in a cell. Light as signal is advantageous due to its precise applicability in time, space, quality, and quantity. Light control of protein stability was achieved by fusing the LOV2 photoreceptor domain ofArabidopsis thalianaphototropin1 with a synthetic degron (cODC1) derived from the carboxy-terminal degron of ornithine decarboxylase to obtain the photosensitive degron (psd) module. The psd module can be attached to the carboxy terminus of target proteins that are localized to the cytosol or nucleus to obtain light control over their stability. Blue light induces structural changes in the LOV2 domain, which in turn lead to activation of the degron and thus proteasomal degradation of the whole fusion protein. Variants of the psd module with diverse characteristics are useful to fine-tune the stability of a selected target at permissive (darkness) and restrictive conditions (blue light).
