Synonyms: amyloid β-peptide | beta-amyloid protein
Comment: We give the sequence for the 42 amino acid peptide here, but note that use of the name β-amyloid generally refers to the ensemble of peptides of 40 to 43 residues excised from the precursor APP protein by the combined action of β- and γ-secretases. These peptides may be soluble monomers or oligomers and contribute to the formation of fibrils and plaques that are associated with Alzheimer's disease.
The amino acid sequences of alternative forms are;
So far we have annotated three types of target relationships for β-amyloid:
1) antibodies directed against the peptide forms for depletion
2) aggregation antagonists
3) imaging reagents for detection
