3-Mercaptopropionic acid NHS ester(CAT: I015251) operates as an alkyl/ether-based linker for constructing PROTACs (PROteolysis Targeting Chimeras). Within the architecture of PROTACs, this linker enables the coupling of two distinct ligands—one designed for an E3 ubiquitin ligase, and the other tailored for the target protein. This strategic connection capitalizes on the intracellular ubiquitin-proteasome system, orchestrating the targeted degradation of specific proteins.
