Amyloid beta peptide 14 (Aβ 33-42)

This part encodes a part of the Amyloid 𝛽 fragment (33-42) which has the ability to bind to A𝛽 plaques inside the brain.

Usage and Biology

Segments of amyloid beta fibrils are widely used as a recognition sequence for amyloid beta plaques inside the brain, this is due to the homotypic interactions in the C-terminus of fibrils. This peptide starts from amino acid 33 to 42 of the fibril.

Modeling

The peptide was modeled by several software (Alphafold-Apptest-Pepfold) and the best model was obtained from Apptest.
