Target Data

Function Promotes microtubule assembly and stability, and might be involved in the establishment and maintenance of neuronal polarity. The C-terminus binds axonal microtubules while the N-terminus binds neural plasma membrane components, suggesting that tau functions as a linker protein between both. Axonal polarity is predetermined by TAU/MAPT localization (in the neuronal cell) in the domain of the cell body defined by the centrosome. The short isoforms allow plasticity of the cytoskeleton whereas the longer isoforms may preferentially play a role in its stabilization.

  14. Report that the interaction of Tau with vesicles results in the formation of highly stable protein/phospholipid complexes.

  17. Because neurofibrillary tangles are aberrant intracellular inclusions formed in the AD patients by hyperphosphorylated tau, it was initially proposed that phosphorylated and/or aggregated intracellular tau protein was causative of neuronal death. However, recent studies suggest a toxic role for non-phosphorylated and non-aggregated tau when it is located in the brain extracellular space. [review] PMID: 29584657

  34. Comparison of the distributions of tau pTyr18 and double-phosphorylated Syk in the transgenic mouse brain and human hippocampus showed that the phosphorylation of tyrosine 18 in tau already occurs at an early stage of tauopathy and increases with the progression of neurodegeneration.
