MINK 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

MINK is a peptide with amino acid sequence of DVQMINKKRK, it is acquired by mirror phage display to inhibit the fibrillization of tau which is one of the main drivers of Alzheimer’s disease and other dementia types. PHF* (VQIINK) is one of the sites that derives tau aggregation. MINK can bind to PHF* in a way that can disrupt the interaction between the fibrils and consequently reduce the aggregates. Its IC50 for inhibition of tau aggregates were 22.6 μM.
