Extended Data Fig. 4: Schematics of tau filament folds.

a–d, Schematics of the tau folds for PSP (a), GGT (b), GPT (c) and AGD (d). Negatively charged residues are shown in red, positively charged residues in blue, polar residues in green, apolar residues in white, sulfur-containing residues in yellow, prolines in purple and glycines in pink. Thick connecting lines with arrow heads are used to indicate β-strands; additional densities are shown in grey.
