Co-factor-free aggregation of tau into seeding-competent RNA-sequestering amyloid fibrils
The authors present a method for the conversion of full-length tau protein into seeding-competent amyloid fibrils without heparin or other negatively charged co-factors, which could be useful for studying the effects of post-translational modifications on Tau aggregation as well as to identify poten...

| Sumario: | The authors present a method for the conversion of full-length tau protein into seeding-competent amyloid fibrils without heparin or other negatively charged co-factors, which could be useful for studying the effects of post-translational modifications on Tau aggregation as well as to identify potential inhibitors of tau aggregation. Biochemical experiments and solid-state NMR spectroscopy measurements show that these co-factor-free tau fibrils have similar properties as amyloid fibrils isolated from brain tissue but differ from those of commonly used heparin-induced tau fibrils. |
