Biochem/physiol Actions

Amyloid plaques characteristic of the Alzheimer brain contain fibrils composed of amyloid beta aggregates. Short peptides containing the sequence KLVFF have been shown to bind specifically to the homologous region in Aβ and are used to prevent full length amyloid fibril formation.

Polymerization of amyloid beta-peptide (Abeta) into amyloid fibrils is a critical step in the pathogenesis of Alzheimer's disease. Here, we show that peptides incorporating a short Abeta fragment (KLVFF; Abeta16-20) can bind full-length Abeta and prevent its assembly into amyloid
L O Tjernberg et al.
The Journal of biological chemistry, 272(19), 12601-12605 (1997-05-09)
We have previously shown that short peptides incorporating the sequence KLVFF can bind to the approximately 40amino acid residue Alzheimer amyloid beta-peptide (Abeta) and disrupt amyloid fibril formation (Tjernberg, L. O., Näslund, J., Lindqvist, F., Johansson, J., Karlström, A. R.
