Tau degradation
WebNov 20, 2024 · The tau aggregation assay is highly reproducible between different wells, experimental runs and batches of the protein. The aggregation leads to tau PHF-like morphology which is very efficient in seeding the formation of de novo fibrillar structures. WebBoth ribosomal-defective tau and tau targeted for turnover are subject to immediate degradation. The exact mechanisms of tau degradation in the human brain are unknown, but have been demonstrated in vitro using the 20S proteasome core [ 12] and non-proteasomal proteases (proteases), such as cathepsin-D [ 13 ], caspases [ 14] and …
