photo-caged PROTACs
Also known as: pc-PROTACs
Taxonomy: Mechanism Branch / Architecture. Workflows sit above the mechanism and technique branches rather than replacing them.
Summary
Photo-caged PROTACs (pc-PROTACs) are light-activated proteolysis-targeting chimeras designed to trigger targeted protein degradation only after irradiation. The reported study presented pc-PROTACs as a general strategy for inducing degradation activity with light and showed that pc-PROTAC1 was potently active in live cells only after light exposure.
Usefulness & Problems
Why this is useful
pc-PROTACs are useful for imposing optical control over PROTAC-mediated protein degradation, enabling degradation activity to be switched on with light rather than being constitutively active. This addresses the need for conditional activation of targeted protein degradation in live-cell settings.

Implementation requires a PROTAC rendered inactive by a photocaging strategy and subsequent light irradiation to activate degradation. The provided evidence confirms live-cell use but does not provide construct chemistry, illumination parameters, or delivery details.
The supplied evidence does not specify the photocaging group, irradiation wavelength, E3 ligase ligand, target protein panel, or quantitative degradation performance. Independent replication and validation breadth beyond the originating study are not documented in the provided material.
