Alzheimer's disease, Huntington's disease and prion diseases are part of a growing list of diseases associated with formation of beta-sheet containing fibrils. In a previous publication, we demonstrated that the self-association of the Alzheimer's beta-amyloid (Abeta) peptide is inhibited by
David J Gordon et al.
Biochemistry, 42(2), 475-485 (2003-01-15)
Protein-protein interactions are frequently mediated by stable, intermolecular beta-sheets. A number of cytokines and the HIV Protease, for example, dimerize through beta-sheet motifs. Evidence also suggests that the macromolecular assemblies of peptides and proteins in amyloid fibrils are stabilized by
