Homomeric self-assembly of peptides into amyloid fibers is a feature of many
diseases. A central role has been suggested for the lateral fiber surface
affecting gains of toxic function. To investigate this, a protein scaffold that
presents a discrete, parallel ?-sheet surface for amyloid subdomains up to eight
residues in length has been designed. Scaffolds that present the fiber surface of
islet amyloid polypeptide (IAPP) were prepared. The designs show
sequence-specific surface effects apparent in that they gain the capacity to
attenuate rates of IAPP self-assembly in solution and affect IAPP-induced
toxicity in insulin-secreting cells.
