Mapping Amyloid Regions in Gad m 1 with Peptide Arrays

Methods Mol Biol. 2018:1779:197-207. doi: 10.1007/978-1-4939-7816-8_13.

Abstract

Amyloid formation is basically featured by a protein-protein interaction in which the reacting regions are the segments assembling into cross β-sheets. To identify these segments both theoretical and experimental tools have been developed. Here, we focus on the use of peptide arrays to probe the binding of several amyloid-specific probes such as the OC and A11 anti-amyloid conformation-selective antibodies and of monomers and preformed fibrils. These arrays use libraries containing partly overlapping peptides derived from the sequence of Gad m 1, the major allergen from Atlantic cod, which forms amyloids under gastrointestinal relevant conditions.

Keywords: Amyloids; Anti-amyloid antibodies; Food allergens; Gad m 1; Peptide arrays.
