Taxonomy: Mechanism Branch / Architecture. Workflows sit above the mechanism and technique branches rather than replacing them.
Summary
pc-PROTAC1 is a photocaged PROTAC construct designed for light-dependent targeted protein degradation in live cells. In the cited study, it exhibited potent degradation activity only after light irradiation, establishing a light-activated degradation strategy.
Usefulness & Problems
Why this is useful
pc-PROTAC1 is useful as a chemical tool for imposing optical control over PROTAC-mediated protein degradation in live cells. The cited work supports its value for experiments requiring degradation activity to be switched on by light rather than being constitutively active.

Source-backed strengths
The key demonstrated strength is potent degradation activity in live cells after light irradiation. The evidence also supports that the inactive-to-active transition is light dependent, consistent with successful photocaging of PROTAC function.
