M4W39 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

M4W39 is a peptide with amino acid sequence of DVWMINKKWK, it is acquired by mirror phage display 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. M4W39 can bind to PHF* in a mean that can disrupt the interaction between fibrils and consequently reduce the aggregates.

IC50 = 2.9 μM
