== Publication Abstract from PubMed == | |||
Structural studies of amyloidogenic segments by X-ray crystallography have revealed a novel packing motif, consisting of out-of-register beta sheets, that may constitute one of the toxic species in aggregation related diseases. Here we sought to determine the presence of such a motif in Islet amyloid polypeptide (IAPP), whose amyloidogenic properties are associated with Type 2 Diabetes. We determined four new crystal structures of segments within IAPP all forming steric zippers. Most interestingly, one of the segments in the fibril core of IAPP forms an out-of-register steric zipper. Analysis of this structure reveals several commonalities with previously solved out-of-register fibrils. Our results provide evidence that out-of-register beta sheets may be a common structural motif in amyloid aggregates and may be associated with toxicity. | |||
