Part:BBa_K4165154

MM3

Tau binding peptide targeting the PHF seed of Tau

Usage and Biology

The amino acid sequence of the MM3 peptide is DPLKARHTSVWY. It is the L-enantiomeric peptide of MMD3 (BBa_K4165141). Its charge is +1, hydrophobicity is 41 %, molecular weight is 1472.65 Da. MM3 can reduce aggregates of full-length tau when mixed in ratio 1:10 and 1:5 and PHF* (VQIINK) but not PHF (VQIVYK).
