Microtubule related protein (MAP) tau is anomalous hyperphosphorylated in Alzheimer's malady (AD) and related tauopathies; in this structure it is the significant protein subunit of combined helical fibers (PHF)/neurofibrillary tangles. Tau protein plays a role in microtubule assembly and dynamics that may regulate neuron morphology. This gene is transcribed into a nuclear RNA that yields six different isoforms, lacking or containing exons 2, 3, and 10 by alternative splicing. 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. Mechanisms involved in hyperphosphorylation of tau are reduced level of protein O-GlcNAcylation, which reciprocally regulates phosphorylation , reduced activity of PP-2A in AD brain, increase in the activities of CaMKII, PKA and MAP kinases, inherited FTDP-17, tau mutations G272V, P301L, V337M and R406W, alterations in PP2A and PP2A regulatory proteins.

Tau, hyperphosphorylation, hexosamine, O-GlcNAcylation, CaMKII, PKA and MAP kinases, FTDP-17, PP2A and PP2A regulatory proteins.
