Structure-guided engineering of an aptamer–PROTAC for targeted degradation of vaccinia-related kinase 1
Vaccinia-related kinase 1 (VRK1) is an oncogenic serine/threonine kinase implicated in tumor progression, yet it remains an intractable target for catalytic degradation. Herein, we report the structure-guided design of a first aptamer–PROTAC chimera for potent and selective degradation of VRK1. Through structure-guided...
