Toolkit/autophagy-targeting chimeras
autophagy-targeting chimeras
Also known as: AUTACs
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: ... autophagy-targeting chimeras (AUTACs) and related tethering strategies...
Usefulness & Problems
Why this is useful
AUTACs are presented as an induced-proximity degrader class linked to autophagy-targeting and related tethering strategies. The review compares their chemistry and mechanism with other modalities.; autophagy-linked targeted degradation; induced-proximity therapeutic design

Ranked Claims
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.
