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.
