Introduction of Linker Design and Optimization
The essence of PROTAC technology lies in its ability to induce the degradation of target proteins by leveraging the cellular ubiquitin-proteasome system. This revolutionary approach offers advantages over traditional inhibition strategies by enabling the selective removal of disease-causing proteins. Central to the efficacy of PROTACs is the design and optimization of the linker connecting the binding moieties, dictating the proximity and orientation crucial for productive protein degradation.
