Description

Tau 2N4R (1–441), P301S is a 441-amino-acid protein corresponding to the complete human tau 2N4R isoform. All residue numbers refer to the 441-residue 2N4R isoform, UniProt P10636-8. The designation 2N4R identifies two N-terminal inserts and four microtubule-binding repeats in the parent protein. Sequence reference: UniProt P10636-8.

Research context

The complete chain includes the N-terminal region, the proline-rich region, all four repeat regions, and the C-terminal extension. This full-sequence context allows comparisons with isolated repeat segments and terminal fragments. The sequence includes PHF6* (VQIINK, residues 275–280) and PHF6 (VQIVYK, residues 306–311), motifs examined in research on tau amyloid assembly. The P301S substitution replaces proline with serine at 2N4R position 301, providing a defined variant for comparison with the unmodified 2N4R sequence.

Tau is a microtubule-associated protein encoded by MAPT. The parent protein contributes to microtubule assembly and stability, while tau self-association and amyloid formation are studied in Alzheimer’s disease and other tauopathies. Sequence-defined proteins and fragments help distinguish the roles of individual regions from the behavior of the complete isoform. Research reference.
