MMD3 Peptide

Tau binding peptide targeting the PHF seed of Tau

Usage and Biology

MMD3 peptide sequence is DPLKARHTSVWY, it is the D-enantiomeric peptide of MM3 (BBa_K4165154). It binds to 275-VQIINK-280 (PHF*) and 306-VQIVYK-311 (PHF) motifs of tau that are reported to drive tau paired helical filament aggregates. it inhibits formation of PHF6* and full‐length Tau aggregates, but not PHF driven aggregates, and prevents the formation of tau β‐sheet‐rich fibrils.
