Selective degradation of protein assemblies, while sparing monomeric forms, is required for interrogation of biological mechanisms and assembly-specific therapeutic intervention. We have exploited the requirement of intermolecular clustering for activation of the E3 ligase TRIM21 to produce TRIM21-nanobody fusions capable of rapidly and selectively degrading assembled proteins. We demonstrate this approach against histone 2B-GFP and tau, a protein that undergoes pathological aggregation in Alzheimer's and other neurodegenerative diseases. Intracellular expression of TRIM21-nanobody degraders prevented or reversed tau aggregation in culture systems and in vivo, with minimal impact on soluble tau. Our results demonstrate that homotypic quaternary structure is a property of proteins that may be exploited for their selective degradation.</p><p>One-Sentence Summary: Redirecting a cytosolic immune pathway enables potent and aggregate-selective removal of pathological tau protein in cell and animal models.</p></div>Lire moins >
