Six tau isoforms
Webb15 dec. 2024 · The Tau isoforms ( Fig. 1) are named 0N3R, 0N4R, 1N3R, 1N4R, 2N3R, and 2N4R, based on the number of amino-terminal exon inserts (0N, 1N, and 2N) or carboxyl-terminal microtubule-binding domain repeats (3R and 4R). These isoforms are normally expressed in the central nervous system. WebbTau occurs in six isoforms due to alternate splicing of exons 2, 3 and 10; the isoforms are named according to the presence of either three or four microtubule-binding domains as the 3R or 4R isoforms, respectively 61. The tau species that occurs in AD is a mixture of 3R and 4R tau. The main function of tau is microtubule stabilization 59 , 60.
