Abstract
Provided are bifunctional molecules that include a first moiety that specifically binds a cell surface molecule or extracellular molecule, and a second moiety that specifically binds a lysosomal targeting molecule. The bifunctional molecules find use, e.g., for targeted degradation of cell surface and extracellular molecules (e.g., proteins) via the endosomal/lysosomal pathway. Also provided are compositions and kits that include the bifunctional molecules, as well as methods of using the bifunctional molecules. Methods of making bifunctional molecules are also provided.
Claims21
A bifunctional molecule comprising:
- a first moiety comprising a protein that specifically binds a cell surface molecule or extracellular molecule;
- and a second moiety comprising a polymer scaffold that displays one or more ligands that specifically bind an asialoglycoprotein receptor (ASGPR), wherein the one or more ligands are selected from N-acetylgalactosamines (GalNAc), galactose, and glucose, and wherein the first moiety and the second moiety are conjugated via a linker.
