m-PEG4-CH2-alcohol is PEG-based based PROTAC linker can be used in the synthesis of PROTACs.
PROTACs contain two different ligands connected by a linker; one is a ligand for an E3 ubiquitin ligase and the other is for the target protein. PROTACs exploit the intracellular ubiquitin-proteasome system to selectively degrade target proteins.
