Background: Tau

Tau is a microtubule-associated protein expressed primarily in neurons.  Carboxy-terminal domains of Tau associate with and stabilize microtubule structure, while other domains bind to the plasma membrane.  Abnormal Tau phosphorylation may result in the self-assembly of tangles of paired helical and/or straight filaments, which are involved in the pathogenesis of Alzheimer's disease and other neurodegenerative diseases.  Properly folded Tau is highly soluble, but when the protein becomes misfolded it forms insoluble aggregates that can damage cytoplasmic functions, interfere with axonal transport and ultimately lead to cell death.
