LYTAC Building Blocks

LYTAC Building Blocks provide an advanced starting point for LYTAC development. LYTAC (LYsosome TArgeting Chimera) molecules are a new approach to Targeted Protein Degradation, which direct an extracellular protein of interest to the lysosome for degradation. LYTACs are heterobifunctional molecules comprising a recruiting molecule for a target protein (e.g. an antibody) joined by a linker to a ligand for a cell surface receptor, such as the cation-independent mannose-6-phosphate receptor (CI-M6PR) or the asialoglycoprotein receptor (ASGPR). The LYTAC forms a ternary complex with the protein of interest and the receptor, triggering internalization of the target protein via endocytosis and its subsequent lysosomal degradation.

Targeted Protein Degradation Poster

Targeted Protein Degradation Poster

Degraders (e.g. PROTACs) are bifunctional small molecules, that harness the Ubiquitin Proteasome System (UPS) to selectively degrade target proteins within cells. They consist of three covalently linked components: an E3 ubiquitin ligase ligand, a linker and a ligand for the target protein of interest. Authored in-house, this poster outlines the generation of a toolbox of building blocks for the development of Degraders. The characteristics and selection of each of these components are discussed.
