WINK Peptide

Tau binding peptide targeting the PHF* seed of Tau

Usage and Biology

WINK is a peptide with amino acid sequence of DVQWINKKRK, it is designed to inhibit the fibrilization of tau which is one of the main drivers of Alzheimer’s disease and other dementia diseases. PHF* (VQIINK) is the site that derive tau aggregation. WINK can bind to PHF* in a mean that can disrupt the interface between each PHF* and consequently reduce the aggregates. Its IC₅₀ for inhibition of tau aggregates were 28.9 μM.
