TROP2‐Targeting Chimeras (TRTACs) for Tumor Cell‐Selective Membrane Protein Degradation and Enhanced Drug Delivery

Extracellular targeted protein degradation (eTPD) systems typically utilize lysosome-targeting receptors (LTRs) to mediate internalization and lysosomal degradation of extracellular and membrane proteins. While multiple LTRs have been discovered, there remains a compelling need to seek for new LTRs, particularly those...

Molecular design and delivery of extracellular and membrane protein degradation chimeras.

This Review provides a framework for selecting disease-matched degradation routes and advancing meTPDs from platform-specific demonstrations towards predictable therapeutic modalities by integrating molecular design, receptor biology, intracellular trafficking, delivery and pharmacodynamic considerations.

Caged Glycan-Antibody Conjugates for Tumor-Selective Activation of Lysosome-Targeting Chimeras.

A chemically activatable LYTAC platform that leverages tumor microenvironment-specific cues to achieve precise and safe protein degradation in vivo is reported, significantly enhancing the safety and therapeutic window of lysosome-targeted degradation strategies in cancer therapy.

Expanding the Repertoire of Lysosomal Degradation of Membrane Proteins: A Generalizable Strategy Using Multivalent Antibody−Polymer Chimeras

It is posited here that multivalent noncovalent interactions can trigger endosomal uptake and lysosomal degradation of specific membrane proteins in combination with an ancillary membrane protein, where the ancillary protein does not need to possess endogenous lysosome-directing characteristics.

Modular Lysosome-Targeting Platform Based on a Multivalent DNA Framework for Programmable Protein Degradation.

Targeted degradation of extracellular and membrane-bound proteins holds immense therapeutic potential but remains technically challenging. Lysosome-targeting chimeras (LYTACs) have emerged to bridge this gap, yet platforms built on monomeric aptamers suffer from inadequate stability, inefficient cellular uptake, and a...

Dissecting PROTAB-mediated degradation of cell surface proteins.

It is shown that PROTAB induces rapid ternary complex formation, followed by receptor internalization and degradation, resulting in ~ 85% target depletion within 24 h, and mechanistically, ubiquitination enhances but is not strictly required for internalization, and degradation proceeds predominantly through the lysoso...
