Webb25 feb. 2024 · Human tau exists as six isoforms, all produced mainly by neurons. A range of post-translational modifications, as well as fragmentation by a variety of proteases, together determine the aggregation and propagation potential of tau ( Quinn et al., 2024 ). Webb15 nov. 2004 · In adult human brain, there are six major isoforms of tau generated by alternative mRNA splicing. Tau has 0, 1 or 2 N-terminal inserts (resulting from the splicing in or out of exons 2 and 3) and either 3 or 4 microtubule-binding domains (resulting from the splicing in or out of exon 10) (reviewed in Johnson and Jenkins, 1999) .
