WebOct 26, 2024 · Introduction. Tau protein is an intrinsically disordered large protein consisting of 441 amino acids including 12 histidyl residues as potential metal binding sites. 1 The biological role of tau protein is associated with its interaction with tubulins to promote their assembly into microtubules and to stabilize the microtubules. 2, 3 Many recent … Six tau isoforms exist in human brain tissue, and they are distinguished by their number of binding domains. Three isoforms have three binding domains and the other three have four binding domains. The binding domains are located in the carboxy-terminus of the protein and are positively charged (allowing it to bind to the negatively charged microtubule). The isoforms with four binding domains are better at stabilizing microtubules than those with three binding domains. Tau is a p…

WebJun 5, 2024 · Overview of tau structure and function. Tau protein is encoded in the microtubule associated protein tau (MAPT) gene on chromosome 17.In the human brain, alternative RNA splicing of exons 2, 3, and 10 lead to the expression of six major tau isoforms: 0N3R, 1N3R, 2N3R, 0N4R, 1N4R, and 2N4R (Fig. 1) [6,7,8].Exon 2 and 3 … WebToxic Aβ species stimulate formation of pathological tau by modulating protein kinases and phosphatases that regulate tau phosphorylation and by inducing tau misfolding. Toxic forms of tau mediate the synaptic dysfunction and neuron death that underlie memory and cognitive impairment in AD, so the signature adverse effects of Aβ require tau. Table.
