Phosphomimetic Tau compatible with pET29b vector

Study of several phosphopathies require specific phosphorylation of certain proteins, which is extremely hard to accomplish practically using random phosphorylation protocols. Study of Tauopathies had been highly restricted because of this shortcoming of the field. However, a much recent development has shown the use of phosphomimetics; replacement of phosphorylable aminoacids (Threonine, Tyrosine and Serine) by Glutamic acid or Aspartic acid, which resemble the charge distribution or structure of a phosphorylation.

The hyperphosphorylation of Tau causes misfolding, oligomerisation and aggreagation, being an unisolable factor in gradual loss of neuron. A few sites have credible statistical and clinical relevance in case of Tauopathies including Alzheimer's disease: 181T, 198S, 199S, 217T, 231T, 396S, 404S, 422S etc. Thus, we changed these particular sites correspondingly in hTau441 sequence which is compatible with pET29b vector plasmid vector.


Usage and Biology

Sites 181T, 198S, 217T, 231T, 396S, 404S and 422S are mutated to phosphomimetic equivalent. The key followed is Serine replaced with Aspartic acid and Threonine replaced with Glutamic acid. This can be used explicitly for studying Alzheimer's like condition in vitro, predicting thermodynamic properties of pTau (process of aggregation) etc, which can help to understand Tauopathy better in the coming future.
