Part:BBa_K4165194
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.
