With the intent of achieving greater spatiotemporal control of PROTAC-induced protein degradation, a light-activated degrader was designed by photocaging an essential E3 ligase binding motif in a BRD4 targeting PROTAC. Proteolysis was triggered only after a short irradiation time, the kinetics of which could be monitored by live-cell video microscopy.
为了实现 PROTAC 诱导的蛋白质降解在更大时空范围内的控制，通过光笼蔽 BRD4 靶向 PROTAC 中必需的 E3 连接酶结合基序来设计光激活降解剂。只有在短时间的辐照后才会触发蛋白水解，其动力学可以通过活细胞视频显微镜进行监测。
