AB - Amyloidogenic proteins share a propensity to convert to the b-structure-rich amyloid state that is associated with the progression of several protein-misfolding disorders. Here we show that a single engineered b-hairpin-binding protein, the bwrapin AS10, binds monomers of three different amyloidogenic proteins, that is, amyloid-b peptide, a-synuclein, and islet amyloid polypeptide, with sub-micromolar affinity. AS10 binding inhibits the aggregation and toxicity of all three proteins. The results demonstrate common conformational preferences and related binding sites in a subset of the amyloidogenic proteins. These commonalities enable the generation of multispecific monomer-binding agents.
