Schematic representation of tau and α-synuclein proteins. A- Alternative splicing of the N1, N1 + N2 and R2 regions (white) yields in 6 different tau isoforms referred to as 0N3R (=tau23 or tau-352), 0N4R (=tau24 or tau-383), 1N3R (=tau37 or tau-381), 1N4R (=tau46 or tau-412), 2N3R (=tau39 or tau-410) and 2N4R (=tau40 or tau-441). Tau has an acidic N-terminus and a tubulin binding region where the vast majority of the exonic (▽) and intronic (not depicted here) disease-associated mutations are found. B- αSyn is a 14.5 kDa protein divided into 3 major regions; the amphipathic N-terminus, the hydrophobic Non-Amyloid Component (NAC) domain, and the acidic C-terminus. Pathogenic missense mutations described to date (▽) are located in the N-terminal region, whereas most disease-related phosphorylation sites (▲) are localized to the C-terminal region of the protein.
