TLKIVW 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

TLKIVW is a hexapeptide designed using Rosetta software and obtained by phage display to bind to VQIVYK (BBa_K4165204) steric zipper motif of tau fibers, which is from the main reasons of the Alzheimer’s disease and other dementia related diseases, this peptide can also prevent further accumulation of tau fibrils.
