Toolkit/lysosome-targeting chimeras
lysosome-targeting chimeras
Also known as: LYTACs
Taxonomy: Mechanism Branch / Architecture. Workflows sit above the mechanism and technique branches rather than replacing them.
Summary
Between 2020 and 2025, major progress has been achieved across five modalities: ... lysosome-targeting chimeras (LYTACs)... Each exploits endogenous degradation or regulatory pathways using chemically engineered bifunctional or monofunctional small molecules.
Usefulness & Problems
Why this is useful
LYTACs are described as a major induced-proximity modality that routes targets into endogenous degradation pathways associated with lysosomal targeting. The review analyzes their chemistry and design principles alongside other degrader classes.; targeted degradation using lysosomal pathways; induced-proximity therapeutic design

Induced-proximity degrader modalities expand the druggable proteome and transcriptome.
These induced-proximity modalities exploit endogenous degradation or regulatory pathways using chemically engineered bifunctional or monofunctional small molecules.
The review identifies five major induced-proximity modalities: PROTACs, molecular glues, LYTACs, AUTACs and related tethering strategies, and RIBOTACs.
