Human tau protein
Tau is a negative regulator of mRNA translation in both Drosophila [13], mouse, [19] and human [20] brains, through its binding to ribosomes, which results in impaired ribosomal function, [21] reduction of protein synthesis and altered synaptic function. [13] [20] Tau interacts specifically with several ribosomal … See more The tau proteins (abbreviated from tubulin associated unit ) are a group of six highly soluble protein isoforms produced by alternative splicing from the gene MAPT (microtubule-associated protein tau). They have roles primarily … See more Microtubule stabilization Tau proteins are found more often in neurons than in non-neuronal cells in humans. One of tau's main functions is to modulate the stability of axonal microtubules. Other nervous system microtubule-associated proteins See more Six tau isoforms exist in human brain tissue, and they are distinguished by their number of binding domains. Three isoforms have three binding … See more Hyperphosphorylation of the tau protein (tau inclusions, pTau) can result in the self-assembly of tangles of paired helical filaments and straight filaments, which are involved in the pathogenesis of Alzheimer's disease, frontotemporal dementia and other tauopathies. … See more In humans, the MAPT gene for encoding tau protein is located on chromosome 17q21, containing 16 exons. The major tau protein in the human brain is encoded by 11 exons. Exons 2, 3 and 10 are alternatively spliced, which leads to the formation of six tau isoforms. In the … See more The accumulation of hyperphosphorylated tau in neurons is associated with neurofibrillary degeneration.
