TD28rev (Tau binding peptide)

A synthetic peptide that is used for targeting misfolded tau protein (BBa_K4165009) as it binds to PHF6 of tau fibrils.

Usage and Biology

A short synthetic peptide acquired by mirror image phage display for binding to tau fibrils at its seed sequence ‘VQIVYK’ called the PHF6. The aggregation of microtubule-associated tau protein starts at this seed to form neurofibrillary tangles inside the brain, which are the main cause of Alzheimer’s disease (AD). Accordingly, this peptide would be suitable to act as our targeting domain for the aggregations.

Dry Lab characterization

Modeling

We modeled the peptide with (Robetta-Itasser-Alphafold-Modeller-TrRosetta)
