Structure and Pathology of Tau Protein in Alzheimer Disease
Figure 1
Amino acid sequence of the longest tau isoform (441 amino acids). N1 and N2: the polypeptide sequences encoded by exons 2 and 3; P1 and P2: proline-rich regions; R1–R4: microtubule-binding domains encoded by exons 9–12; 275VQIINK280 and 306VQIVYK311: sequences with β-structure (modified by [13]).
