Oligomeric
amyloid-β is currently of interest in amyloid-β mediated toxicity and
the pathogenesis of Alzheimer’s disease. Mapping the amyloid-β
interaction partners could help to discover novel pathways in disease
pathogenesis. To discover the amyloid-β interaction partners, we applied
a protein array with more than 8100 unique recombinantly expressed
human proteins. We identified 324 proteins as potential interactors of
oligomeric amyloid-β. The Gene Ontology functional analysis of these
proteins showed that oligomeric amyloid-β bound to multiple proteins
with diverse functions both from extra and intracellular localizations.
This undiscriminating binding phenotype indicates that multiple protein
interactions mediate the toxicity of the oligomeric amyloid-β. The most
highly impacted cellular system was the protein translation machinery.
Oligomeric amyloid-β could bind to altogether 24 proteins involved in
translation initiation and elongation. The binding of amyloid-β to
purified rat hippocampal ribosomes validated the protein array results.
More importantly, in vitro translation assays showed that the
oligomeric amyloid-β had a concentration dependent inhibitory activity
on translation. Our results indicate that the inhibited protein
synthesis is one of the pathways that can be involved in the
amyloid-beta induced neurotoxicity.
